| 1 | LA-ICP-MS zircon U-Pb dating from granitoids in southern basement of Songliao basin:Constraints on ages of the basin basement显示文摘Seven LA-ICP-MS zircon U-Pb datings from granitoids in the southern basement of the Songliao basin were done in order to constrain the ages of the basin basement. The cathodoluminescence (CL) images of the zircons from seven granitoids indicate that they are euhedral-subhedral ones with striped ab-sorption and obvious oscillatory zoning rims. The dating results show that a weighted mean 206Pb/238U age is 236±3 Ma for quartz diorite (sample No.T6-1) located in the western slope of the basin,that weighted mean 206Pb/238U ages are 319±1 Ma (2126 m) and 361±2 Ma (1994 m) for diorite (sample No.YC1-1) and granite (sample No.YC1-2) located in northern part of southeastern uplift of the basin,respectively,and that weighted mean 206Pb/238U ages are 161±5 Ma,165±2 Ma,165±1 Ma and 161±4 Ma for samples Q2-1,SN121,SN122,and SN72 granitoids located in southern part of southeastern uplift of the basin,respectively. The statistical results of ages suggest that the middle Jurassic granitoids con-stitute the main part of basement granitoids,and that the Hercynian and Indo-Sino magmatisms also occur in the basin basement. It is implied that the Songliao basin should be a rift one formed in the intracontinent or active continental margin settings in the late Mesozoic after the Middle Jurassic orogeny took place. | GAO FuHong XU WenLiang YANG DeBin PEI FuPing LIU XiaoMing HU ZhaoChu | 2007 | Science China Earth Sciences2007，50，7： | 31 |
| 2 | The diversity effect of inductive reasoning under segment manipulation of complex cognition显示文摘The present study proposed the idea of segment manipulation of complex cognition (SMCC), and technically made it possible the quantitative treatment and systematical manipula-tion on the premise diversity. The segment manipulation of complex cognition divides the previ-ous inductive strengths judgment task into three distinct steps, attempting to particularly distin-guish the psychological processes and their rules. The results in Experiment 1 showed that compared with the traditional method, the quantitative treatment and systematical manipulation of SMCC on the diversity did not change the task’s nature, and remain rational and a good measurement of inductive strength judgment. The results in Experiment 2 showed that the par-ticipants’ response rules in the triple-step task were expected from our proposal, and that in Step 2 the “feeling of surprise” (FOS), which seems implausible but predicted from the diversity premises, was measured, and its component might be the critical part that produced the diversity effect. The “feeling of surprise” may reflect the impact of emotion on cognition, representing a strong revision to premise probability principle of pure rational hypothesis proposed by Lo et al., and its roles in the diversity effect are worthy of further research. In this regards were discussed the mistakes that the premise probability principle makes when it takes posterity probability as prior probability. | CHEN Antao LI Hong FENG Tingyong GAO Xuemei ZHANG Zhongming LI Fuhong YANG Dong | 2005 | Science China(Life Sciences)2005，48，6： | 5 |
| 3 | A Transgressive Depositional Setting for the Paleogene Shahejie Formation in the Qikou Depression, Eastern China: Inferences from the REE Geochemistry of Carbonates显示文摘Rare earth element(REE) and Y concentrations, and ^(87)Sr/^(86)Sr ratios were analyzed in 33 carbonate samples from the Paleogene Shahejie Formation in the Qikou depression, eastern China, with the goal of determining depositional environments and post-depositional conditions of carbonates in the region. The REE and Y concentrations were normalized to the post-Archean Australian shale(PAAS) standard. The La_(PAAS)~*/Yb_(PAAS)~* ratios of 0.35–1.52, where _(PAAS)~* indicates values for the PAAS standard, show light REE enrichment and heavy REE depletion in most samples. Values of La_(PAAS)~*(0.775–1.284) and Ce_(PAAS)~*(0.822–1.224), coupled with a relatively flat REE distribution, indicate that the Shahejie carbonates were deposited in lacustrine environments. Values of Y anomalies(1.009–1.527) and Y/Ho ratios(28.43–45.00) in the Shahejie Formation are greater than those of lacustrine carbonates and closer to those of marine carbonates, indicating that diagenetic fluids were probably influenced by seawater. In the carbonates from Well Kou-42, Eu anomalies(1.171–1.604), ^(87)Sr/^(86)Sr ratios(0.708 001–0.710 893), and high homogenization temperatures(104–151℃) suggest that the carbonates were affected by hydrothermal fluids. The REEs and Sr isotope ratios show that the carbonates from the Shahejie Formation in the Qikou depression were deposited in lacustrine environments, and were influenced by seawater and hydrothermal fluids. | Yang Yang Fuhong Gao Changwei Chen Xiugang Pu | 2018 | Journal of Earth Science2018，29，2： | 2 |

| 5 | Geochemical characteristics of Early Cretaceous source rocks in Boli Basin显示文摘The Early Cretaceous deposits are composed of important source rocks in Boli Basin. The types of the source rocks include black mudstones and coal (with carbonaceous mudstone). By the organic geochemical analysis methods, the authors discussed the organic petrological characters, abundance of organic matter, degree of maturity and the type of source rocks. The main micro-component of black mudstone is exinite or vitrinite, and the content of vitrinite is high in coal. The weathering of the outcrop is very serious. The abundance of organic matter in source rock reaches the poor to better rank. The major kerogens in mudstone are type-Ⅲ, type-Ⅱ 2 and some type-Ⅱ 1; the organic type of coal is type-Ⅲ. The thermal evolution of the source rocks in every structural unit is very different, from low-maturity to over-maturity. The depositional environment is reductive, which is good for the preservation of organic matter. The organic matter in source rocks is mainly from aquatic organisms and terrigenous input. | Hongmei Gao Fuhong Gao Fu Fan Yueqiao Zhang | 2006 | Global Geology2006，9，1： | 1 |
| 6 | Recognition and Significance of Volcanic Rocks of the Anda Depression of the Songliao Basin in Jurassic-Cretaceous显示文摘A series of volcanic rocks were developed in the deep part of Anda faulting depression. The reflection of the rocks are mainly stratiform and hummocky. Three kinds of volcanic facies, e.g. explosion facies, effusion facies and sub-volcanic facies,were recognized by different reflecting characteristics in the seismic profile. The volcanic rocks are formed during three episodes of volcanic activities from Shahezi Formation to Yingcheng Formation. The volcanisms have relation to the formation of Songliao Basin and regional tectonics of northeastern China. Some of the volcanic rocks are good oil and gas reservoirs. | Fuhong Gao Dongpo Wang Xinrong Zhang Guixia Ji Jian Zhao | 2003 | Global Geology2003，8，1： | 0 |
| 7 | Geochemistry of solvable organic matter from source rocks in Shangkuli Formation of Labudalin Basin显示文摘A suit of lacustrine source rocks are developed in volcanic deposits in the Shangkuli Formation of the Cretaceous. However, it is poor to understand the characteristics of source rocks due to the low degree of exploration, thus the exploration is severely constrained in this area. Based on the geochemical analysis, the analytic technique of GC and GC-MS, combined with the characteristics of solvable organic matter and biomarkers of the source rocks, the authors discussed the depositional environment, the derivation of the matrix and the maturity characteristics of the organic material of the Shangkuli Formation in Cretaceous. The results show that the organic matter mainly belongs to type Ⅱ1 kerogen, whose abundance is relatively high; it was formed in reductive surrounding where was deep-lake; the hydrocarbon is characterized by mixed-source of organic matter. The thermal evolution of source rocks had reached maturation stage. | GAO Fuhong GAO Hongmei FAN Fu YANG Yang | 2010 | Global Geology2010，13，2： | 0 |
| 8 | Genesis and significance of quartz cement in sandstones显示文摘Quartz cement as syntaxial overgrowths is one of the most abundant cements in sandstones. Distribution of quartz cement in time and space indicates that the more younger the stratigraphy is, the more smaller the amount of quartz cement, and the amount of quartz cement increases with increasing of depth and basin type also is a factor which controls the amount of quartz cement. The sources of silica for quartz cement have many different opinions, but there is one or more dominant sources. Temperature and pH of fluid are major factors which influence the precipitation of quartz cement. There exist three hypotheses on the flow of pore fluid and transport and precipitation of silica, that is, the hypothesis of cycle of shallow underground water, the hypothesis of high concentration of fluid driven by compaction and the hypothesis of diffusion and recycle of local fluid. The research of quartz cement is significant for the timing of paleotemperature, heterogeneity of reservoir, physical property of reservoir and the timing of oil immersion, etc. | Yu Junmin, Liu li, Gao Fuhong and Zou Haifeng (Changchun University of Science and Technology, Changchun 130026) Yang Yongchang, Sun Xiaoming and Zhang Liqin (Geology and Development Institute,Dagang Oil Field Group Ltd., Tianjin 300280) | 1999 | Global Geology1999，4，1： | 0 |
| 9 | Diagenesis characteristics and their influence on porosity and permeability of sandstone from Yingcheng Formation in Jinshan field显示文摘In order to understand the diagenesis and its influence on porosity and permeability of sandstones from Yingcheng Formation in Jinshan field,applying thin sections,casting and scanning electron microscope,the authors studied petrography,diagenesis,porosity and permeability of Yingcheng Formation sandstone reservoir. The results show that the reservoir of Yingcheng Formation is mainly composed of lithic arkoses. Sandstones experienced compaction,pressolution,cementation,metasomatism and dissolution. The primary pores of the sandstones are undeveloped; most of pores are the secondary pores,which are mainly intragranular dissolution pores in feldspar and debris. The compaction and cementation reduced the primary pores in sandstones,the porosity and permeability decreased; while the dissolution formed the secondary pores,resulting in the porosity and permeability increase. Due to compaction and cementation,the porosity and permeability are reduced with increasing of depth. There exists an abnormal enlargement of porosity and permeability within a depth range 2310--2450 m. In combination with analysis of petrology,the dissolution of feldspar and debris is most developed in the depth range. Therefore,compaction,cementation and dissolution are the important factors which affect the porosity and permeability of sandstones. | ZHANG Ruiyao GAO Fuhong ZHANG Zhongyue | 2014 | Global Geology2014，17，4： | 0 |
