| 1 | 华南地区中生代以来岩石圈伸展及其与铀成矿关系研究的若干问题显示文摘华南地区中生代以来存在大规模的岩石圈伸展作用,与伸展作用相对应,形成了大量花岗岩型、火山岩型和碳硅泥岩型铀矿床。文章详细总结了华南中生代以来岩石圈伸展作用和铀成矿作用的研究进展。通过系统分析,认为要深刻揭示岩石圈伸展与区域铀成矿的关系,至少尚有两大重要科学问题未解决:其一是华南白垩纪—第三纪岩石圈伸展和铀成矿的准确期次及其空间迁移规律;其二为岩石圈伸展期铀成矿的必然性或铀为什么会集中在岩石圈伸展期成矿。要解决第一个问题,需要对铀矿床和岩石圈伸展期形成的基性脉岩开展系统的高精度定年工作;要解决第二个问题,则需要系统研究成矿流体中CO2等气体组分在铀成矿中的作用及其成因。 | 胡瑞忠 毕献武 彭建堂 刘燊 钟宏 赵军红 蒋国豪 | 2007 | 矿床地质2007，26，2： | 178 |
| 2 | On the timing and duration of the destruction of the North China Craton显示文摘The timing and duration of the destruction of the North China Craton, which is pivotal to understanding the destruction mechanism and its geodynamic controlling factors, still remain controversial. On the basis of the principles of magma genesis and evolution, first we outline magmatic expressions that can be related to cratonic destruction, then use magmatic and basin evolution trends to constrain the timescale of the lithospheric thinning in North China. The main conclusions include: (1) the thinning of the lithosphere beneath the North China Craton might have started, at least locally, since late Carboniferous-late Triassic, attained its climax during the late Jurassic-early Cretaceous, and continued till the end of late Cretaceous-early Cenozoic. The destruction of the North China Craton was a relatively slow, rather than a dramatic process. (2) The weakened lithospheric zones along the margins and interiors of the craton played an important role in cratonic destruction, partly accounting for the heterogeneous pattern of cratonic destruction. (3) The tectonic factors that controlled the destruction of the North China Craton may be multiple. The late Carboniferous southward subduction of the Paleo-Asian plate and the late Triassic collision between North China and South China may have re-activated the craton by influencing the thermal and integral structure of the craton. The Pacific subduction underneath the eastern Asian continent played a determinant role in the cratonic destruction, governing the distribution patterns of post-Mesozoic basins and major tectonic configuration, temporal change of magmatism and formation of the North-South gravity lineament. | XU YiGang LI HongYan PANG ChongJin HE Bin | 2009 | Chinese Science Bulletin2009，54，19： | 70 |
| 3 | 东海盆地中、新生代盆架结构与构造演化显示文摘基于地貌、钻井、岩石测年和地震等资料,分析盆地地层分布、盆架结构、构造单元划分和裂陷迁移规律,结果表明东海盆地由台北坳陷、舟山隆起、浙东坳陷、钓鱼岛隆褶带和冲绳坳陷构成,是以新生代沉积为主、中生代沉积为辅的大型中、新生代叠合含油气盆地;古元古代变质岩系构成了盆地的基底。该盆地不仅是印度-太平洋前后相继的动力体系作用下形成的西太平洋沟-弧-盆构造体系域一部分,而且也是古亚洲洋动力体系作用下形成的古亚洲洋构造域和特提斯洋动力体系作用下形成的特提斯洋构造域一部分,晚侏罗世至早白垩世经历了构造体制转换,盆地格局发生重大变革,早白垩世以前主要受古亚洲-特提斯洋构造体制影响的强烈挤压造山和地壳增厚作用演变为早白垩世以来主要受太平洋构造体制控制的陆缘伸展裂陷和岩石圈减薄作用,经历侏罗纪古亚洲-特提斯构造体制大陆边缘拗陷和白垩纪以来太平洋构造体制弧后裂陷两大演化阶段。白垩纪以来太平洋构造体制的弧后裂陷演化阶段可细分为早白垩世至始新世裂陷期、渐新世至晚中新世拗陷期和中新世末至全新世裂陷期。 | 刘金水 许怀智 蒋一鸣 王军 何新建 | 2020 | 地质学报2020，94，3： | 26 |
| 4 | 合肥盆地中生代地层时代与源区的碎屑锆石证据显示文摘合肥盆地位于大别造山带北侧、郯庐断裂带西侧,其发育过程与这两大构造带演化密切相关。本次工作对合肥盆地南部与东部出露的中生代砂岩与火山岩进行了锆石年代学研究,从而限定了各组地层的沉积时代,确定了火山岩喷发时间,指示了沉积物的源区。这些年代学数据表明,合肥盆地南部的中生代碎屑岩自下而上分别为下侏罗统防虎山组、中侏罗统圆筒山组或三尖铺组、下白垩统凤凰台组与周公山组(或黑石渡组)与上白垩统戚家桥组,其间缺失上侏罗统。盆地东部白垩系自下而上为下白垩统朱巷组与响导铺组和上白垩统张桥组。该盆地出露的毛坦厂组或白大畈组火山岩喷发时代皆为早白垩世(130~120 Ma)。盆地南部的下——中侏罗统及白垩系源区皆为大别造山带,分别对应该造山带的后造山隆升与造山后伸展隆升。而盆地东部白垩系的源区始终为东侧的张八岭隆起带,后者属于郯庐断裂带伸展活动中的上升盘。 | 王薇 朱光 张帅 刘程 顾承串 | 2017 | 地质论评2017，63，4： | 23 |
| 5 | The Yanshan orogeny and late Mesozoic multi-plate convergence in East Asia—Commemorating 90th years of the “Yanshan Orogeny”显示文摘The Yanshan movement/orogeny has been proposed for 90 years, which is of special significance in the history of geological research in China. This study conducted a review by synthesizing major achievements regarding episodic deformation features, sedimentary and magmatic records of the Yanshan orogeny in China, and clarified the episodic tectono-magmatism and its geodynamic origins. The tectonic implications of the Yanshan orogeny are discussed in the context of global plate tectonics and supercontinent reconstruction. Lines of evidence from structural, sedimentary and magmatic data suggest that the Yanshan orogeny represents a regional-scale tectonic event that affected the entire China continent in late Mesozoic period. Numerous age and structural constraints consistently indicate that the Yanshan orogeny was initiated in the Jurassic(at ~170±5 Ma). and was characterized by alternating stages of crustal shortening at ~170–136 Ma, crustal extension at ~135–90 Ma, and weak shortening at ~80 Ma. The 170–136 Ma crustal shortening was reflected in the generation of two regional stratigraphic unconformities(the Tiaojishan and Zhangjiakou unconformities), which were initially named the A and B episodes of 'the Yanshan Orogeny' by Mr.Wong Wenhao in 1928. Geodynamically, the Yanshan orogeny in East Asia was associated with nearly coeval oceanic subduction and continental convergence in the Paleo-Pacific, Neo-Tethys, and Mongol-Okhotsk tectonic domains. As a consequence, three giant accretionary-collisional tectonic systems were formed along the continental margins of East Asia, i.e., the Mongol-Okhotsk, Bangonghu-Nujiang, and SE China subduction-and collision-related accretionary systems. The Yanshan orogeny induced widespread crustal-scale folding and thrusting, tectonic reactivation of long-lived zones of crustal weakness,and extensive magmatism and mineralization in intraplate regions. Based on the time principle of supercontinent assembly and break-up, we propose that the mid-Late Jurassic multi-plate convergence in East Asia might represent the initiation of the assembly of the Amasia supercontinent, and the Yanshan orogeny might be the first 'stirrings' that is a prerequisite for the birth of the Amasia supercontinent. | Shuwen DONG Yueqiao ZHANG Hailong LI Wei SHI Huaimin XUE Jianhua LI Shiqi HUANG Yongchao WANG | 2018 | Science China Earth Sciences2018，61，12： | 21 |
| 6 | Subduction and retreating of the western Pacific plate resulted in lithospheric mantle replacement and coupled basin-mountain respond in the North China Craton显示文摘The North China Craton(NCC) witnessed Mesozoic vigorous tectono-thermal activities and transition in the nature of deep lithosphere. These processes took place in three periods:(1) Late Paleozoic to Early Jurassic(~170 Ma);(2) Middle Jurassic to Early Cretaceous(160-140 Ma);(3) Early Cretaceous to Cenozoic(140 Ma to present). The last two stages saw the lithospheric mantle replacement and coupled basin-mountain response within the North China Craton due to subduction and retreating of the Paleo-Pacific plate, and is the emphasis in this paper. In the first period,the subduction and closure of the PaleoAsian Ocean triggered the back-arc extension, syn-collisional compression and then post-collisional extension accompanied by ubiquitous magmatism along the northern margin of the NCC. Similar processes happened in the southern margin of the craton as the subduction of the Paleo-Tethys ocean and collision with the South China Block. These processes had caused the chemical modification and mechanical destruction of the cratonic margins. The margins could serve as conduits for the asthenosphere upwelling and had the priority for magmatism and deformation. The second period saw the closure of the Mongol-Okhotsk ocean and the shear deformation and magmatism induced by the drifting of the Paleo-Pacific slab. The former led to two pulse of N-S trending compression(Episodes A and B of the Yanshan Movement) and thus the pre-existing continental marginal basins were disintegrated into sporadically basin and range pro vince by the Mesozoic magmatic plutons and NE-SW trending faults.With the anticlockwise rotation of the Paleo-Pacific moving direction, the subduction-related magmatism migrated into the inner part of the craton and the Tanlu fault became normal fault from a sinistral one. The NCC thus turned into a back-arc extension setting at the end of this period. In the third period, the refractory subcontinental lithospheric mantle(SCLM) was firstly remarkably eroded and thinned by the subduction-induced asthenospheric upwelling, especially those beneath the weakzones(i.e.,cratonic margins and the lithospheric Tanlu fault zone). Then a slightly lithospheric thickening occurred when the upwelled asthenosphere got cool and transformed to be lithospheric mantle accreted(~125 Ma) beneath the thinned SCLM. Besides, the magmatism continuously moved southeastward and the extensional deformations preferentially developed in weak zones, which include the Early Cenozoic normal fault transformed from the Jurassic thrust in the Trans-North Orogenic Belt, the crustal detachment and the subsidence of Bohai basin caused by the continuous normal strike slip of the Tanlu fault, the Cenozoic graben basins originated from the fault depression in the Trans-North Orogenic Belt, the Bohai Basin and the Sulu Orogenic belt. With small block size, inner lithospheric weak zones and the surrounding subductions/collisions, the Mesozoic NCC was characterized by(1) lithospheric thinning and crustal detachment triggered by the subduction-induced asthenospheric upwelling.Local crustal contraction and orogenesis appeared in the Trans-North Orogenic Belt coupled with the crustal detachment;(2)then upwelled asthenosphere got cool to be newly-accreted lithospheric mantle and crustal grabens and basin subsidence happened, as a result of the subduction zone retreating. Therefore, the subduction and retreating of the western Pacific plate is the outside dynamics which resulted in mantle replacement and coupled basin-mountain respond within the North China Craton. We consider that the Mesozoic decratonization of the North China Craton,or the Yanshan Movement, is a comprehensive consequence of complex geological processes proceeding surrounding and within craton, involving both the deep lithospheric mantle and shallow continental crust. | Jianping ZHENG Hongkun DAI | 2018 | Science China Earth Sciences2018，61，4： | 20 |
| 7 | 燕山褶断带下板城盆地杏石口组沉积特征及其构造意义显示文摘本文通过对燕山褶断带下板城盆地杏石口组沉积物的成分、古水流及其底部砾岩的砂质充填物中碎屑锆石和砾岩中部出露的花岗岩、花岗片麻岩砾石中锆石LA-ICP-MS U-Pb测年分析结果,并结合来源区的构造与岩浆作用的调查,揭示了杏石口组沉积时环境的剧变。三叠纪时期刘家沟组至二马营组均为河流相沉积,其古流向自东向西,而杏石口组沉积期变为快速堆积的山麓冲积扇相砾岩,古流向自北-北西向南-南东。杏石口组一段至二段的沉积特征记录了该时期内蒙古隆起的构造抬升及剥露过程。杏石口组中碎屑锆石和花岗岩、花岗片麻岩砾石中锆石U-Pb年龄范围可分为3组:2025~2565Ma、1659~1888Ma和193~691Ma。其中,最年轻的碎屑锆石的加权平均年龄为197±6Ma,表明杏石口组的砂砾岩沉积时代应晚于197±6Ma,即其沉积时代应为早侏罗世。笔者曾获得下板城盆地北侧王土房杂岩体中不同单元花岗岩的锆石U-Pb年龄为191±1Ma和207±1Ma,其与本文获得杏石口组中最年轻的碎屑锆石及两枚花岗岩砾石中锆石的加权平均年龄197±6Ma和206±2Ma、207±2Ma在误差范围内一致,表明与王土房杂岩体同期侵位的岩体在杏石口期发生了快速抬升剥露。暗示了内蒙古隆起在早侏罗世发生了快速抬升及剥露的构造过程。结合前人研究,燕山褶断带前180Ma构造幕发生时代应在197~180Ma期间。 | 刘健 赵越 柳小明 刘晓文 | 2007 | 岩石学报2007，23，3： | 17 |
| 8 | 冀西北尚义盆地对晚侏罗世构造活动的沉积响应显示文摘尚义盆地位于走向近东西的中生代燕山冲断带前缘盆地群的西段,在晚侏罗世土城子时期堆积了大量的粗碎屑。盆地中土城子组沉积相变明显,自北向南从粗砾质变为粉砂质沉积,具比较典型的非对称相带分布特征。土城子早一中期,从北向南总体上形成砾质冲积扇(包括泥石流)-辫状河流-洪泛平原或干化湖泊等古环境布局。晚期则以砂砾质辫状河流沉积为主,可能夹有发育大型风成交错层理的砂质沙丘沉积。土城子组碎屑成分以变质岩和花岗质岩石为主.物源主要来自盆地北侧的'内蒙地轴',沉积充填具有同构造砾岩的性质。尚义盆地北缘发育一系列呈叠瓦状排列的逆冲断裂。断裂与盆地耦合关系的初步分析显示.北缘逆冲断裂的构造载荷是控制尚义盆地形成和演化的主要因素。靠近北部冲断带一侧沉积相序的中—下部具有向上变粗的特点.可能指示了土城子组沉积受前进式的冲断载荷和岩石圈挠曲控制的过程。根据尚义盆地与其北侧相关断裂的空间配置、沉积碎屑北粗南细的变化、盆地横断面北厚南薄的楔状体特征等分析.盆地属于陆内的前陆式盆地,推测是在自北向南的近水平挤压构造背景下形成的. | 和政军 牛宝贵 张新元 | 2008 | 中国地质2008，35，2： | 16 |
| 9 | 燕山构造带滦平早白垩世盆地沉积过程和演化显示文摘滦平盆地是燕山构造带内一个具有代表性的早白垩世伸展盆地。对盆地内沉积岩相和相组合的详细分析结果显示,盆地内部发育不同的沉积相带并显示明显的空间变化。盆地北部和西部边缘以冲积扇砾岩和扇三角洲砂岩、砾岩沉积为主,盆地中心为湖泊细粒沉积。河流相砂岩和砾岩主要分布于盆地的东南部。古流向和物源恢复结果证明,盆地沉积物主体来自于北部和西部老变质岩基底,仅少部分沉积物来自盆地的东南缘。盆地构造沉降和沉积充填过程主要受北缘和西缘张性断层的控制,断层下盘基底岩石的抬升与盆地边界正断层活动相关,从而成为盆地主要的物源区。滦平盆地的演化可划分为三个阶段:即早期火山喷发阶段、中期强烈断陷阶段和晚期填平阶段。滦平盆地代表了早白垩世燕山构造带其它同类盆地的发展过程,它们皆以小型独立的盆地发育为特征。 | 张英利 渠洪杰 孟庆任 | 2007 | 岩石学报2007，23，3： | 15 |
| 10 | Discussion on the relationship between the Yanshanian Movement and cratonic destruction in North China显示文摘The relationship between the Yanshanian Movement, destruction of the North China Craton(NCC), and subduction of the western Pacific plate is crucial to reconstructing the middle-late Mesozoic tectonic evolution of the eastern Asian continent and margin. The Yanshanian Movement was a globally important change in crustal tectonics during the Middle-Late Jurassic.Previous research has systematically studied the formation and evolution of the Yanshanian Movement, focusing on the timing and location of tectonic movements, and the sedimentary and volcanic strata. However, the question of whether the tectonic activity occurred globally, and the characteristics of the Yanshanian Movement remain debated. The main argument is that if a tectonic movement can only be characterized by a regional or local disconformity, and if the tectonic movement occurred in an intracontinental setting, with extensive deformation but with no disconformity despite volcanic eruptions and magmatic intrusions, accompanied by changes in crustal structure and composition, should it be defined as a tectonic event or process? This question requires further analysis. The main aim of this study is to distinguish whether the Yanshanian Movement is a local feature of the eastern Asian continent, or a global tectonic event related to subduction of the Pacific Plate. In this paper, based on previous research, we discuss the spatial and temporal evolution of the Yanshanian Movement, the controlling tectonic mechanisms, and its relationship to the reactivation and destruction of the NCC and the subduction of the western Paleo-Pacific slab.We emphasize that the Yanshanian Movement in the Middle-Late Jurassic is distinct from the lithospheric thinning responsible for Early Cretaceous extension and magmatism related to the destruction of the NCC. The various tectonic stages were constrained by different dynamics and tectonic settings, or by different tectonic events and processes. Therefore, it is possible that the deformation and reactivation of the NCC contributed to its destruction, in addition to lithospheric thinning. Finally, we discuss whether the Yanshanian Movement was associated with the destruction of the NCC. | Yu WANG Lixin SUN Liyun ZHOU Yueting XIE | 2018 | Science China Earth Sciences2018，61，5： | 13 |
| 11 | Destruction of North China Craton:Insights from temporal and spatial evolution of the proto-basins and magmatism显示文摘Temporal and spatial evolution of proto-basins and magmatism in the North China Craton might provide information of its destruction.Overall,the destruction of the North China Craton is a heterogeneous process of bottom upward and from margin toward interior,related to multiple interactions between the craton and its surrounding plates.The interior of craton would be initially destructed during the Early-Middle Jurassic.Subduction of the Paleo-Asian Ocean Plate may have destructed the northern margin of the North China Craton.Collision of the Yangtze Plate with the North China Craton is significant for the magmatic and tectonic activities during the Late Triassic-Middle Jurassic.Subductions of the Izanagi and Paleo-Pacific plates lead to the ultimate destruction of the North China Craton.Temporal and spatial evolution of the proto-basins and related magmatism in the North China Craton indicate that the dominant mechanism of the cratonic destruction may be thermal mechanical-chemical erosion. | LI HongYan | 2013 | Science China Earth Sciences2013，56，3： | 12 |
| 12 | 华北晚中生代构造演化过程——根据太行山北部盆地沉积记录显示文摘太行山北部地区处于燕山山脉和太行山山脉的交汇处,其侏罗纪—白垩纪叠加盆地发育过程记录了东西向盆地向北东向盆地转化过程,对刻画华北晚中生代陆内变形过程及其动力学背景具有重要意义。本文以太行山北部草沟堡盆地和招柏盆地为例,在盆地基本构造格架分析的基础上,通过详细的沉积物物源分析、盆地原型再造等沉积学方法,结合岩浆岩同位素年代学数据,提出太行山北部晚中生代构造演化过程,主要经历四个发展演化阶段,包括中侏罗世晚期近南北向构造挤压与挠曲盆地发育、晚侏罗世近南北向弱伸展作用与壳源火山喷发、晚侏罗世末期—早白垩世早期北西—南东向构造挤压与前陆盆地形成、早白垩世北西—南东向伸展作用与幔源火山作用。构造体制转变本质上是动力学体系的转变,在中晚侏罗世东亚大陆多向汇聚体系之下,太行山北部经历的多期构造叠加和盆地叠置过程折射了蒙古—鄂霍茨克构造体系向滨太平洋构造体系的转化过程。 | 王永超 董树文 施炜 岑敏 李江瑜 | 2016 | 地球学报2016，37，1： | 11 |
| 13 | 燕山构造带中段早白垩世盆地特征显示文摘燕山构造带中段主要包含3个早白垩世盆地,即滦平盆地、凤山盆地、石人沟盆地。通过对盆地的沉积相分析、古水流的恢复以及盆地构造-沉积演化研究,认为燕山构造带中段早白垩世盆地发育分为三个阶段,即早期火山喷发阶段、中期强烈断陷阶段和晚期填平阶段。早期发育强烈的火山作用,形成以酸性火山岩为主的张家口组;中期盆地主体呈半地堑状,受单一边界主断层控制,盆地相互独立,盆地边缘以冲积扇砾岩和扇三角洲砂岩、砾岩沉积为主,盆地中心为湖泊细粒沉积。古流向和物源恢复结果证明,盆地沉积物主体来自于北部和/或西部的变质岩基底。盆地构造沉降和沉积充填过程主要受边界正断层的控制,断层下盘基底岩石的抬升与盆地边界正断层活动相关,从而成为盆地主要的物源区。 | 张英利 孟庆任 | 2008 | 吉林大学学报(地球科学版)2008，38，4： | 7 |
| 14 | Syn-tectonic sedimentation and its linkage to fold-thrusting in the region of Zhangjiakou, North Hebei, China显示文摘The timing of the 'Yanshanian Movement' and the tectonic setting that controlled the Yanshan fold-and-thrust belt during Jurassic time in China are still matters of controversy. Sediments that filled the intramontane basins in the Yanshan belt perfectly record the history of 'Yanshanian Movement' and the tectonic background of these basins. Recognizing syn-tectonic sedimentation, clarifying its relationship with structures, and accurately defining strata ages to build up a correct chronostratigraphic framework are the key points to further reveal the timing and kinematics of tectonic deformation in the Yanshan belt from the Jurassic to the Early Cretaceous. This paper applies both tectonic and sedimentary methods on the fold-and-thrust belt and intramontane basins in the Zhangjiakou area, which is located at the intersection between the western Yanshan and northern Taihangshan. Our work suggests that the pre-defined 'Jurassic strata' should be re-dated and sub-divided into three strata units: a Late Triassic to Early Jurassic unit, a Middle Jurassic unit, and a Late Jurassic to early Early Cretaceous unit. Under the control of growth fold-and-thrust structures, five types of growth strata developed in different growth structures: fold-belt foredeep type,thrust-belt foredeep type, fault-propagation fold-thrust structure type, fault-bend fold-thrust structure type, and fault-bend foldthrust plus fault-propagation fold composite type. The reconstructed 'source-to-sink' systems of Late Triassic to Early Jurassic,Middle Jurassic and Late Jurassic to early Early Cretaceous times, which are composed of a fold-and-thrust belt and flexure basins, imply that the 'Yanshanian Movement' in our study area started in the Middle Jurassic. During Middle Jurassic to early Early Cretaceous times, there have been at least three stages of fold-thrust events that developed 'Laramide-type' basementinvolved fold-thrust structures and small-scale intramontane broken 'axial basins'. The westward migration of a 'pair' of basement-involved fold-thrust belt and flexure basins might have been controlled by flat subduction of the western Paleo-Pacific slab from the Jurassic to the Early Cretaceous. | Shaofeng LIU Chengfa LIN Xiaobo LIU Qitian ZHUANG | 2018 | Science China Earth Sciences2018，61，6： | 6 |
| 15 | 中国东部大陆岩石圈地幔置换作用的内外原因显示文摘克拉通大陆通常有古老、巨厚且难熔的岩石圈地幔。这种地幔高度亏损玄武质组分,有密度低、刚性程度高的特点,能长期漂浮于软流圈之上而稳定存在。中国东部大陆主要由华北和华南两个古老地块在古生代—早中生代沿中央造山带拼合形成,在晚中生代时强烈活化,表现为构造变形、盆地形成、岩浆活动、巨量成矿等,其深部原因是什么?在分析东部大陆形成过程和岩石圈地幔属性基础上发现:块体初始规模小且发育薄弱带,后期容易受改造;特别是显生宙以来中国大陆受周边多个构造域夹持,板块俯冲作用会引起软流圈物质扰动和上涌并沿薄弱带侵蚀和改造上覆岩石圈,使之发生有效减薄、明显再富集和最终地幔置换。改造和置换后的岩石圈地幔富含玄武质组分,有较高密度和较低刚性程度,容易发生变形和部分熔融,使克拉通大陆活化。因此,块体规模大小并发育薄弱带以及周边构造环境是大陆稳定性控制重要的内、外在因素;中国东部大陆岩石圈显生宙强烈活化和地幔置换是由于块体规模较小而且周边多体系俯冲作用等内、外在有利因素协同作用下的结果。 | 郑建平 | 2020 | 地质力学学报2020，26，5： | 5 |
| 16 | 燕山构造带凤山盆地早白垩世的沉积过程显示文摘凤山盆地是燕山构造带内的一个早白垩世伸展盆地。盆地内沉积岩相和相组合的详细分析结果显示,盆地内部发育不同的沉积相带,并显示明显的空间变化。盆地北部和西部边缘以冲积扇砾岩和扇三角洲砂岩、砾岩沉积为主,盆地中心为湖泊细粒沉积。古流向和物源恢复结果证明,盆地沉积物主体来自北部和西部变质岩基底。盆地构造沉降和沉积过程主要受北缘和西缘张性断层的控制。断层下盘基底岩石的抬升与盆地边界正断层活动相关,从而成为盆地主要的物源区。凤山盆地的演化可划分为3个阶段,即早期火山喷发阶段、中期强烈断陷阶段和晚期填平阶段。 | 张英利 孟庆任 渠洪杰 | 2008 | 地质学报2008，82，6： | 5 |
| 17 | 冀西北赤城—宣化盆地土城子组沉积特征及盆缘构造分析显示文摘为了揭示华北北部晚侏罗世沉积盆地性质,对赤城—宣化盆地中土城子组沉积特征及盆缘构造进行了研究。通过对土城子组沉积特征研究表明,土城子组中—下部为一套河湖相沉积,上部为一套冲积扇粗碎屑沉积;土城子组砾岩成分系统统计分析显示,赤城盆地与宣化—下花园盆地具有相似岩屑岩性相旋回,反映源区具有相同或相近的蚀顶过程。研究区晚侏罗世盆地中土城子组充填特征及盆缘构造特征表明,土城子组形成于挤压构造背景,土城子组沉积时期盆地受控于盆缘逆冲断层。大地构造背景暗示,赤城—宣化盆地晚侏罗世—早白垩世期间,古太平洋板块向NW方向的俯冲作用与尚义—赤城断裂向南逆冲并伴随右旋走滑作用是土城子组沉积时期盆地格局形成的重要控制因素。 | 刘晓波 刘少峰 林成发 | 2016 | 吉林大学学报(地球科学版)2016，46，5： | 4 |
| 18 | Growth structures and growth strata of the Qianjiadian Basin in the western Yanshan fold and thrust belt, North China显示文摘The northwestward subduction of the Izanagi Plate beneath the eastern Eurasian Plate during the Late Mesozoic caused a series of compressional deformation events in the Yanshan fold and thrust belt(YFTB), but the tectonic deformation timing, tectonic properties and relationship between tectonic uplift and sediment accumulation in the intermontane basins continue to be debated. For this reason, the sedimentology, sediment provenance, and basin structure of the Qianjiadian Basin(QJB) in the northern Beijing region during the Late Jurassic and Early Cretaceous were studied in detail. The results suggest that a fault-propagation fold-type(FPFT) growth structure and growth strata developed on the western edge of the QJB and that the top part of Member 2 and Member 3 of the Tuchengzi Formation are growth strata controlled by the limb rotation mechanism. In two small thrust faults in the QJB, the Mesoproterozoic Xiamaling Formation is thrust over the Tuchengzi Formation, and these faults may have controlled the development of the fault-bend fold-type growth strata. An analysis of the 'source-to-sink' process suggests that the hanging wall succession of the Shangyi-Pingquan fault(SPF) was the main source area of the Late Jurassic to early Early Cretaceous strata in the QJB. A zircon206 Pb/238 U age of 140.8±2.4 Ma for the volcanic rocks at the bottom of the FPFT growth strata represents the timing of the initiation of FPFT growth structure development. The discovery of the FPFT growth structure and growth strata in the QJB indicate that the QJB was an intermontane flexural basin controlled by fold and thrust structures during the early Early Cretaceous. Near the E-W-trending SPF, the NE-SW-trending Qianjiadian thrust fault(QJTF) and two small intrabasinal thrust faults may constitute a unified right-lateral strike-slip system that formed in response to the northwestward flat subduction of the Izanagi Plate beneath the East Asian continent during the Jurassic-Early Cretaceous. | Xiaofei SHI Shaofeng LIU Chengfa LIN | 2019 | Science China Earth Sciences2019，62，7： | 4 |
| 19 | 宝坻断层的几何学与运动学特征:兼论燕山褶皱带与渤海湾盆地的构造关系显示文摘宝坻断层是渤海湾盆地西北缘的边界正断层,地处燕山褶皱带与渤海湾盆地耦合的关键部位。宝坻断层处在古亚洲构造域与太平洋构造域的交叠部位,经历了复杂的构造演化过程,其在中生代-新近纪的构造活动控制了武清凹陷的沉积和构造演化。宝坻断层整体走向近EW向,延伸长度约68km,最大位移达14. 2km,滑脱面深度约10~15km。横向上其主体断面及滑脱面均存在较明显的分段性,通过3个垂向转折轴面可划分为4段。剖面上该断层大部分呈上陡下缓的犁式正断层特征,中段部分区域为'坡坪式'结构。宝坻断层整体位移在横向上的变化与其几何学上的分段有着较好的相关性,表明其现今多次转折的结构与其生长过程密切相关。古近系底面、东营组底面及新近纪底面位移-距离曲线特征表明,沙河街组沉积期,各个断层在相对独立发育后,因横向生长而逐渐发生硬连接,至东营组沉积期之前形成整体断面,其活动于新近纪逐渐减弱,所控断陷规模萎缩。中生代以来,武清凹陷-燕山褶皱带主要受三叠纪、早中侏罗世、中晚侏罗世、白垩纪、古近纪和新近纪-第四纪6个构造演化阶段的影响,其中,三叠纪-侏罗纪末期,武清凹陷与燕山褶皱带经历了相似的构造演化过程,而自白垩纪以来,两者的构造-沉积响应出现了明显的分异。因此对宝坻断层及武清凹陷的构造解析对厘定燕山构造带陆内变形的时空范围及其与渤海湾盆地的耦合关系有着重要意义。 | 张煜颖 何登发 单帅强 崔永谦 | 2019 | 岩石学报2019，35，4： | 4 |
| 20 | 伸展构造与华北克拉通破坏——花岗岩磁组构和变质核杂岩的构造分析显示文摘中生代以来,华北克拉通岩石圈发生大规模减薄,岩石圈地幔的物理、化学性质发生显著改变,这一过程通常被称为华北克拉通破坏.目前在华北克拉通东部大规模发育的岩浆岩是岩石圈深部减薄过程在浅部的重要响应,也是克拉通破坏在浅部的直接表现.岩体侵位机制和侵位过程与大地构造背景密切相关,并记录同期区域大地构造信息.15年来,通过对华北克拉通东部不同岩浆发育阶段(晚三叠世、早侏罗世、晚侏罗世、早白垩世早期及早白垩世晚期)22个花岗岩体开展磁化率各向异性(AMS)的研究,反演岩体的就位过程;结合早白垩世早期广泛发育的变质核杂岩,探讨岩体侵位的构造背景,进一步约束华北克拉通在不同阶段的构造背景及其与克拉通破坏的相关性.其中,晚三叠世、早侏罗世和晚侏罗世岩体均具有一致的N(E)-S(W)向的磁线理,早白垩世早期岩体和变质核杂岩以NW-SE向(磁)线理为主,早白垩世晚期岩体的磁线理则比较分散.结合区域构造,我们推断晚三叠世、早侏罗世和晚侏罗世岩体侵位受区域N(E)-S(W)向弱伸展构造体系的控制,早白垩世早期岩体侵位则受区域NW-SE向伸展构造体系的控制,而早白垩世晚期岩体就位与先期浅表弱伸展已经产生空间相关.总而言之,华北克拉通中生代伸展构造经历了从N(E)-S(W)向NW-SE的转变,并体现出阶段性由弱渐强的表现.上述伸展构造发育方向的转变可能代表蒙古-鄂霍茨克带和古太平洋板块与欧亚大陆东部相互作用过程. | 林伟 曾纪培 孟令通 邱华标 卫巍 任志恒 褚杨 李双建 宋超 王清晨 | 2021 | 中国科学:地球科学2021，51，9： | 3 |
