REE Geochemistry in the Weathered Crust of Granites, Longnan Area, Jiangxi ProvinceAbstract Warm and humid climate and gentle hilly topography have provided favourable conditions for the development of the weathering crust of the granite intrusions in the Longnan area, Jiangxi Province. REE is mostly concentrated in an adsorption state in clay in the wholly weathered zone. The rare‐earth minerals enriched in the parent rocks provided the source mat...

Marine Geohazards: Review and Future PerspectiveAbstract With offshore resource exploration moving to the deep water, marine geohazards have been attracting attention from the academic and industry. Research achievements of marine geohazards were reviewed in this paper. We analyzed and discussed typical issues among marine geohazards, including coastal erosion, submarine slope failure, turbidity current and speci... ... hiện toàn bộ

U‐Pb Age and Hf Isotope Study of Detrital Zircons from the Wanzi Supracrustals: Constraints on the Tectonic Setting and Evolution of the Fuping Complex, Trans‐North China OrogenAbstract: Located in the middle segment of the Trans‐North China Orogen, the Fuping Complex is considered as a critical area in understanding the evolution history of the North China Craton (NCC). The complex is composed of various high‐grade and multiply deformed rocks, including gray gneiss, basic granulite, amphibolite, fine‐grained gneiss and marble, metamorphos...

Lower Triassic and Induan‐Olenekian Boundary in Chaohu, Anhui Province, South ChinaAbstract: Since the West Pingdingshan Section in Chaohu was proposed as the candidate of the Global Stratotype Section and Point of the Induan‐Olenekian boundary in 2003, the Lower Triassic of Chaohu has been extensively studied. Based on the studies on the Lower Triassic of Chaohu, (1) a continuous conodont zonation is established, which has become an important ref... ... hiện toàn bộ

Large Tetrapod Burrows from the Permian Naobaogou Formation of the Daqingshan Area, Nei Mongol, ChinaAbstract Two new tetrapod burrow casts from the Naobaogou Formation (Middle or Late Permian) of Nei Mongol, China are described. It marks the first pre‐Cenozoic tetrapod burrow from China, and one of the earliest records of tetrapod burrows. Comparison to other Permian and Triassic burrows suggests that these burrows were created by tetrapod slightly smaller than ... hiện toàn bộ

Late Jurassic–Early Cretaceous Plutonism in the Northern Part of the Precambrian North China Craton: SHRIMP Zircon U–Pb Dating of Diorites and Granites from the Yunmengshan Geopark, BeijingAbstract: The Yunmengshan Geopark in northern Beijing is located within the Yanshan range. It contains the Yunmengshan batholith, which is dominated by two plutons: the Yunmengshan gneissic granite and the Shicheng gneissic diorite. Four samples of the Yunmengshan gneissic granite give SHRIMP zircon U–Pb ages from 145 to 141 Ma, whereas four samples of the Shicheng ... ... hiện toàn bộ

New Approaches and Markers for Identifying Secondary Biogenic Coalbed GasAbstract: According to the adsorption‐desorption characteristics of coalbed gas and analysis of various experimental data, this paper proposes that the generation of secondary biogenic gas (SBG) and its mixing of with the residual thermogenic gas at an early stage inevitably lead to secondary changes of the thermogenic gas and various geochemical additive effects. E... ... hiện toàn bộ

The Occurrence of Oleananes in the Beibuwan Basin and Its Application to the Study of Maturity and Oil‐Source Rock CorrelationAbstract: The oleanane parameter, i.e., OP (oleananes/(oleananes+C30 hopanes)) in the two sedimentary columns of the Beibuwan Basin, South China Sea, can be used to delimit the top of oil generation window, with R o (/%) of 0.53 in Well M1 and 0.55 in Wells H1/Hd1/Hd2, respectively. Comparing with vit...
