1西宁黄土堆积记录的最近13万年高原季风气候变化显示文摘青藏高原对于大气的热力和动力作用形成了高原季风气候现象。青藏高原东北部西宁盆地位于高原季风控制区 ,末次间冰期以来的黄土堆积记录了高原季风气候变化过程。对西宁盆地湟水阶地上的黄土堆积进行了地貌观查、地层对比和探槽及探井采样 ,完成了热释光和光释光测年 ,测量了古地磁定向样品以及磁化率、频率磁化率、CaCO3含量和粒度等古气候代用指标。结果表明 ,西宁黄土堆积记录的高原夏季风环流在相当于深海氧同位素阶段5e特别强 ,在 5a和 5c阶段接近于阶段 3。高原夏季风和冬季风变化存在位相差以及冬季风强的时候夏季风不一定弱 。鹿化煜 马海州 谭红兵 李珍 苗晓东 安芷生 王晓勇 曹广超 Jef Vandenberghe 2001第四纪研究2001,21,5:37
2青藏高原东北部地貌演化与隆升显示文摘揭示青藏高原生长过程和重建不同时期的古高度,是备受关注的科学问题。在青藏高原东北部,广泛分布的高大山系和盆地,是高原地貌演化的结果,也成为认识高原隆升过程的重要地质记录。对西宁盆地的沉积分析表明,这里的山盆体系在距今~50 Ma就开始发育,并相对稳定地持续到了16~10 Ma,表明这段时间高原东北部已经基本形成。在16~10 Ma,盆地河湖相沉积停止,遭受侵蚀、河流开始下切,指示这时有一次重要的构造活动和地面抬升。在~2.0 Ma以来,广泛发育的河流阶地序列(高度差达400 m以上),指示了气候变化和构造活动对地貌的影响;存在的数百米的河流阶地高差、河流侵蚀速率近10倍的增加是地面构造抬升控制河流下切的证据,指示青藏高原东北部在~2.0 Ma以来的抬升。西宁盆地及其周边山系地貌发育过程,可能是高原东北部隆升对欧亚和印度板块碰撞和挤压响应的体现。鹿化煜 王先彦 VANDENBERGHE Jef 2014自然杂志2014,36,3:9
3Climatic and tectonic controls on the fluvial morphology of the Northeastern Tibetan Plateau (China)显示文摘The geomorphological evolution of the Northeastern Tibetan Plateau(NETP)could provide valuable information for reconstructing the tectonic movements of the region.And the considerable uplift and climatic changes at here,provide an opportunity for studying the impact of tectonic and monsoon climate on fluvial morphological development and sedimentary architecture of fluvial deposits.The development of peneplain-like surface and related landscape transition from basin filling to incision indicate an intense uplift event with morphological significance at around 10–17 Ma in the NETP.After that,incision into the peneplain was not continuous but a staircase of terraces,developed as a result of climatic influences.In spite of the generally persisting uplift of the whole region,the neighbouring tectonic blocks had different uplift rates,leading to a complicated fluvial response with accumulation terraces alternating with erosion terraces at a small spatial and temporal scale.The change in fluvial activity as a response to climatic impact is reflected in the general sedimentary sequence on the terraces from high-energy(braided)channel deposits(at full glacial)to lower-energy deposits of small channels(towards the end of the glacial),mostly separated by a rather sharp boundary from overlying flood-loams(at the glacial-interglacial transition)and overall soil formation(interglacial).Pronounced incision took place at the subsequent warm-cold transitions.In addition,it is hypothesized that in some strongly uplifted blocks energy thresholds could be crossed to allow terrace formation as a response to small climatic fluctuations(10~3–10~4 year timescale).Although studies of morpho-tectonic and geomorphological evolution of the NETP,improve understanding on the impacts of tectonic motions and monsoonal climate on fluvial processes,a number of aspects,such as the distribution and correlation of peneplain and the related morphological features,the extent and intensity of tectonic movements influencing the crossing of climatic thresholds,leading to terrace development,need to be studied further.WANG Xianyan Jef VANDENBERGHE LU Huayu Ronald VAN BALEN 2017Journal of Geographical Sciences2017,27,11:6
4Distribution and Forming Model of Fluvial Terrace in the Huangshui Catchment and its Tectonic Indication显示文摘黄水河,黄河的一条主要支流,穿过显示出梯田的不同模式的一系列构造地减退并且高举的区域形成。黄水河的河的梯田的分发被学习通过地志并且印射的 sedimentologic 梯田。在 Haiyan 盆的三个平台,在 Huangyuan 盆的四个平台,在 Xi'ning 盆的 19 个平台(四个高平台可以属于另一条河) ,在 Ping'an 盆,在 Ledu 盆的五个平台和在 Minhe 盆的 12 个平台的九个平台被认出。Sedimentology 研究证明黄水河的 geomorphologic 和 sedimentological 模式,在西藏的边缘被定位,与在另外的区域的河的不同。平台的形成过程在黄水集水是更复杂的:累积平台和侵蚀梯田在每盆被形成,当侵蚀平台在另外的盆被形成时,累积平台在一些盆被开发,显示河的沉积可以与在另外的盆的河切口同时发生在一些盆。在黄水集水的这些二种河的平台的形成过程的一个概念的模型在这篇论文向前被带。首先,因为气候的变化或构造运动,河的平衡状态被打破,并且河在整个集水在所有盆切入直到到达一个新平衡状态。然后,下游的盆快速减退并且平衡状态再被打破,并且当河快速在沉淀盆积累时,河在在上游的盆切入直到再走近一个新平衡州。最后,因为气候的变化或构造运动和累积平台,河在整个集水切入当侵蚀平台在另外的盆被形成时,在沉淀盆被形成。累积平台的存在在黄水集水在亚盆暗示了构造沉淀。这些构造沉淀运动逐渐地从下游的 Minhe 盆发展了到在上游的 Huangyuan 盆。标明日期平台顺序有潜力揭开在在集水的沉淀之间的关系并且地区性在东北西藏的高原构造。WANG Xianyan LU Huayu Jef VANDENBERGHE CHEN Zhongyan LI Langpin 2010Acta Geologica Sinica(English Edition)2010,84,2:3
5内蒙古鄂尔多斯高原古冰缘遗迹科学考察研究进展显示文摘冰缘遗迹(特别是冷生楔形构造及融冻褶皱)是重建古气候及第四纪晚期多年冻土环境的重要证据。内蒙古鄂尔多斯高原是我国北方地区冰缘现象最为发育的地区之一。为准确了解鄂尔多斯高原冰缘遗迹类型及其分布特征、区域冻土演化历史等,中国科学院西北生态环境资源研究院和荷兰自由大学共同组成科研小组,于2018年5—6月组织了'鄂尔多斯高原冰缘遗迹科学考察'。考察区域涉及靖边—城川—乌审旗—鄂尔多斯东胜区一带约12000km2的范围。考察内容主要包括鄂尔多斯高原冰缘遗迹类型及特征、分布区域、各类型冰缘遗迹所指示的气候条件的初步推断等。结果表明:冻融褶皱和冷生楔体构造是鄂尔多斯高原主要存在的两大类冰缘遗迹。基于本次考察中关于冰缘遗迹的分布与特征等新发现,并综合前人研究成果,初步推断:在气温极低、多年冻土非常发育的时段,有利于形成各类冷生楔状构造,如冰楔假形和大型原生砂楔等;在气候转暖、多年冻土退化,但还没有全部融化完阶段,可能形成融冻褶皱;区域性大面积分布和成群出现的融冻褶皱一般反映较暖气候环境下,多年冻土层上部已退化到一定程度。基于光释光(OSL)年代测试结果,结合冰缘遗迹的特征及其所指示的古气候环境,初步重建了鄂尔多斯5万年以来的冻土环境变化序列。区内多年冻土在多年冻土最大期(LPM,25~19ka BP)时最发育,以大面积连续多年冻土为主;之后,随气温转暖,总趋势呈退化状态,多年冻土分布逐渐变为片状→岛状→零星斑状,直至现今全部融完变为深季节冻土区。何瑞霞 金会军 蒋观利 张泽 陈雪梅 Raul David SERBAN Mihaela SERBAN Jef VANDENBERGHE Valentin V.SPEKTOR Hugh M.FRENCH 2021冰川冻土2021,43,1:2

13Possible controlling factors in the development of seasonal sand wedges on the Ordos Plateau,North China显示文摘Wedge-like structures filled with silty sand penetrate Quaternary fluvial and aeolian sediments and, in places, Tertiary bedrock on the Ordos Plateau, North China. The wedges reflect thermal contraction cracking of either permafrost or seasonal frost during the Late Pleistocene and early Holocene. Wedges of about 1 m in depth form polygonal nets of 2-3 m in diameter(type B). They contrast with wedges of 3-4 m in depth that form polygons of 10-15 m in diameter(type A).This review focuses upon the highly variable size of the inferred polygon nets and discusses the problem of differentiating between seasonally and perennially frozen ground, or between seasonal frost and permafrost.Hugh MFrenchψ Jef Vandenberghe HuiJun Jin RuiXia He 2021Research in Cold and Arid Regions2021,13,2:0
14Legacy: Hugh French and his significance for periglacial environment and permafrost studies显示文摘Hugh French passed away unexpectedly on May 11, 2019, at the age of 76. His influence on the research and teaching in the fields of periglacial environment, permafrost and civil engineering can hardly be overstated. Out of his numerous international contacts, impressive publication records, memberships of international organizations and committees, and awards(Guglielmin and Murton, 2019)。Jef Vandenberghe 2021Research in Cold and Arid Regions2021,13,2:0
15Distribution and Formation of Fluvial Terraces in Huangshui Catchment(Northeastern Tibetan Plateau) and Its Tectonic Implication显示文摘River evolution at margins of the Tibetan Plateau may provide valuable information for understanding climatic change and tectonic movement of the past. Here we focus on the Huangshui River,a tributary of the Yellow River,crossing a series of tectonically subsided and uplifted areas that show diversity patterns of terrace formation.The distribution of fluvial terrace is studied by mapping and dating.Three terraces in Haiyan basin,four terraces in Huangyuan basin,19 terraces in Xi’ning basin,nine terraces in Ping’an basin,five terraces in Ledu basin and 12 terraces in Minhe basin are recognized.Magne-Jef Vandenberghe 2009地学前缘2009,16,S1:0
