1Depositional Model for Peat Swamp and Coal Facies Evolution Using Sedimentology, Coal Macerals, Geochemistry and Sequence Stratigraphy显示文摘As one of the most important source rocks and reservoirs of unconventional natural gas, the sedimentary environment and mode of peat swamp(the predecessor of coal seam) is important to the coal seam's spatial distribution, material composition, hydrocarbon generation potential, reservoir physical properties, etc. To reveal the depositional characteristics and history of environmental change in a terrestrial basin during a period of peat accumulation, the Middle Jurassic aged #7 coal from Gaoquan in the Qaidam Basin(NW China) was investigated using sedimentology, maceral composition, geochemistry and sequence stratigraphy. Based on identification of the sedimentary shoreline break belt, wave energy depletion point and position of wave base, the peat swamp system can be subdivided into(1) lakeside plain,(2) low energy lakeshore,(3) high energy lakeshore, and(4) shallow lake subfacies. A new method for determining coal facies is proposed based on the combination of environmental parameters including oxidation-reduction levels, energy conditions and the influence of terrigneous sediments. The evolution of the coal seam shows that peat was deposited mainly in the low energy lakeshore and lakeside plain subfacies. Five types of sequence stratigrpahic surface and two types of parasequence were identified. Forced lake regressions and normal lake regressions are attributed as the causes of sequence boundaries. The sequence stratigraphic framework comprises six sequences and corresponding system tracts, and the curve of base-level for each demonstrates a characteristic initial period of slow rising followed by fast rising and then returning to slow rising. A model indicating the relationship among base-level changes, coal facies evolution, and the environmental features in the swamp is proposed that shows the environmental features of the swamp were controlled by both base-level changes and coal facies. Accompanying depositional environment changes from a lakeside plain to lakeshore and shallow lake caused by increasing rate of base-level rise, water paleosalinity, acidity and the percentage of woody plants decrease, and the bog type alters from the low marsh to raised bog.Jing Lu Longyi Shao Minfang Yang Kai Zhou James R.Wheeley Hao Wang Jason Hilton 2017Journal of Earth Science2017,28,6:5

5Continental chemical weathering during the Early Cretaceous Oceanic Anoxic Event(OAE1b): a case study from the Fuxin fluvio-lacustrine basin, Liaoning Province,NE China显示文摘This study focuses on Early Cretaceous mudstones from the Shahai and Fuxin formations in the Fuxin continental basin. We analyse chemical weathering, land surface temperatures and palaeoclimates based on chemical weathering indices, and emphasize the implications of continental chemical weathering on nutrient fluxes into lakes and oceans.According to Cr and Ni abundance, Al2O3-TiO2, La/Sc-Th/Co and V-Ni-Th×10 plots, as well as rare earth element(REE)analysis, mudstone samples from the Shahai and Fuxin formations were derived from the same type of provenance comprising mainly felsic igneous rocks. Chemical weathering trends reflected by the Chemical Index of Alteration(CIA),Weathering Index of Parker(WIP) and the Mafic Index of Alteration for Oxidative weathering environments(MIA(O)) are consistent with each other and allow the geological succession to be divided into four stages. Land surface temperatures of the Shahai and Fuxin formations are estimated based on the linear relationship of CIA to temperature,and also can be divided into four stages consistent with those determined from chemical weathering trends. During Stage A(early part of the late Aptian) chemical weathering and land surface temperatures were relatively low and showed characteristic high fluctuations, while Stage B(latest Aptian) represented a transitional period where weathering rates and temperatures increased, and high amplitude fluctuations continued. Conditions changed markedly in Stage C(early Albian) with very high and stable weathering, and warm, humid climates, while in Stage D(middle and late Albian) conditions returned to low chemical weathering and land surface temperatures. These stages of chemical weathering and land surface temperature fluctuations represent responses to global climate fluctuations during the Early Cretaceous, with the early Albian high weathering intensities and warm, humid climates combining to create high nutrient levels that would have flushed through rivers into lakes and ultimately oceans. This correlates stratigraphically with the development of Early Cretaceous black shales during Ocean Anoxic Event 1 b, showing the importance of continental weathering regimes as a causal mechanism for lake and ocean anoxia.Xiao-Tao Xu Long-Yi Shao Bo Lan Shuai Wang Jason Hilton Jian-Yi Qin Hai-Hai Hou Jie Zhao 2020Journal of Palaeogeography2020,9,2:1
6Redefining the Age of the Cenozoic Shanwang Formation in Shanwang Basin显示文摘Objective The Shanwang Basin is a small Cenozoic sedimentary basin located in Linqu county,Shandong province.The Shanwang Formation,especially the diatomaceous shale member,contains diverse and finely preserved flora and fauna fossils(Fig.1).Previous paleontological study and radiometric dating show that it was formed in the Miocene.However,on the precise age of the formation,there are such different opinions as Late Miocene。YU Jifeng ZHAO Xiangguang PANG Xinlong JASON Hilton FU Wenzhao ZHAO Xiuli SONG Zhaojun HU Jialiang LU Lei ZHANG Hongjun YANG Ziqun QIAO Wenyan SHI Suo 2017Acta Geologica Sinica(English Edition)2017,91,4:1

10种子植物的起源及其早期演化显示文摘迄今为止世界上最早的种子植物发现于北美和欧洲西北部的晚泥盆纪地层。这些种子植物可能起源于前裸子植物,即解剖构造上较为进化的一类蕨类植物。然而,从目前的证据来看尚无法确切判断这些种子植物起源于前裸子植物中的某个特定类群,比如古羊齿目和戟枝木目。作者总结了种子植物祖先的有关证据,并对目前已知的最早的种子植物的形态进行了概述。由于种子植物自出现起即表现出丰富的形态多样性,因而尚无法对某个可能的祖先形态作出判断。目前的研究尚不能确切回答种子植物起源的全部问题,仍需寻找有关前裸子植物与种子植物过渡类型的新证据。Jason Hilton  (Department of Palaeobotany, Institute of Botany, The Chinese Academy of Sciences, Beijing 100093) 1998Acta Botanica Sinica1998,40,11:0
