Summary: The study focused on the relationship between the color of Cenozoic Himalayan foreland basin sediments and tectonics/climate, revealing specific connections between red and grey facies with tectonic pulses and climate cycles. Further investigations at various temporal and spatial scales are needed to utilize sediment color as an indicator of specific climate.

Summary: The origin and formation mechanism of crude oil and natural gas in the southern slope zone of the Kuqa foreland basin were studied by analyzing their compositions and geochemical characteristics. The crude oil in this region is mainly of continental origin, while the natural gas is predominantly derived from coal. The presence of updip pinch-out sand bodies and plugging secondary faults is important for the exploration and development of oil and gas resources in this area.

Summary: The Paleogene sedimentary successions of the Tarim Basin in western China are reconstructed to understand the palaeogeographic evolution and palaeoenvironmental changes. The study reveals the major regression of the proto-Paratethys Sea, the transition from marine to continental-lacustrine sedimentation, and the role of tectonic and eustatic forces in controlling the late Paleogene transgression regression. The findings provide insights into the sedimentary response to Paleogene sea-level change and tectonic events in Central Asia.

Summary: The Junggar Basin is a typical oil basin with a high potential for natural gas exploration. It has a proven ratio of natural gas and has developed effective reservoirs and thick caprocks in most areas. The research results and exploration practice show that the basin has a relatively large natural gas exploration potential.

Summary: This study evaluated the source rocks and reservoirs in the Ordovician lower assemblage in Ordos Basin through drilling cores, well logging and seismic data. The natural gas identified is high thermal evolution dry gas from marine source rock, characterized by specific isotopic features. The distribution of reservoirs is controlled by palaeo-uplift during the sedimentary period.

Summary: The preparation of all-silica SIT zeolite membranes on four-channel hollow fibers enables efficient separation of helium and nitrogen as well as helium and methane. These membranes operate at atmospheric temperature, exhibit high selectivity and significant enhancement of helium concentration, and demonstrate good stability in practical applications.

Summary: The study collected muddy water and gas samples from the most active mud volcanism region in China over the course of a year, analyzing them for major molecular compositions. The emitted gases primarily consist of CH4, with higher amounts of cations and anions in water during spring and summer compared to autumn and winter. Additionally, there is a clear seasonal trend in gas fluxes.

Summary: The paper investigates the volcanic rock suite in the Halahatang area of the northern Tarim Basin, including basalt and trachy-andesite. The results show that these rocks were formed approximately 290 million years ago, which is generally synchronous with the main episode of magmatism within the Permian Tarim large igneous province. The compositions of the rocks indicate that the basalt shares similarities with typical oceanic island basalts, while the trachy-andesite shows higher enrichments in incompatible elements. The study reveals close relationships between these rock components and interactions between the lithosphere and mantle during magma evolution.

Summary: This study investigates the gas dryness coefficients of different oil and gas reservoirs in the Cainan oil gas field in the Junggar Basin. The results show that the mixing of gases from multiple sources and the diffusion process during accumulation are the major constraints on dryness coefficients. These factors lead to both vertical and horizontal changes in the dryness coefficients. The study provides insights into the reasons for the changes in gas dryness coefficients and contributes to understanding the source and accumulation process of natural gas.

Summary: The majority of high quality clastic reservoirs in the foreland basins of northwest China have anomalously high primary porosity. The influence of intensive tectonic compression, overburden, and overpressure on deep reservoir quality in the foreland basins has been poorly researched. This study used a comprehensive numerical model to simulate various geological models of tectonic compression, overpressure, and porosity, and quantitatively discussed their influences on deep reservoir porosity. The results showed that the coupling of tectonic compression and overpressure in the early-middle slow burial and late rapid burial phases best preserved high porosity within reservoirs in a case study of the Junggar foreland basin. The late stage tectonic compression accompanied by overpressure had the largest influence on porosity.

Summary: The gas-rich northern Shuntuoguole area in the Tarim Basin has been a subject of debate regarding the origin of its natural gas. However, an analysis of the geological context, natural gas components, and isotope ratios provides evidence that methane is the main component of alkane gases in the region. The carbon isotope fractionation of alkane gases indicates that they are associated with oil and derive from I type kerogen. Additionally, the study reveals that the primary source of natural gas in the Shunbei area is the cracking of kerogen, with a contribution from oil cracking gas. Exploration and development of petroleum in this area are justified based on the Ordovician source rocks as the primary origin of natural gas.

Summary: Based on the analysis of Upper Paleozoic source rocks, source-reservoir-caprock assemblage, and gas accumulation characteristics in the Ordos Basin, a gas accumulation geological model for the total petroleum system is determined. The main controlling factors of gas accumulation and enrichment are discussed, and the gas enrichment models of the total petroleum system are established, showing the distribution and enrichment of gas in the basin. The results reveal that source rocks, faults, and tight reservoirs control the distribution and enrichment of gas, with inner-source tight gas and near-source tight gas being the focus of exploration in the Ordos Basin.

Summary: The interplay between late Paleozoic tectonics at the marginal and intraplate regions of southeastern Laurentia is a subject of debate. This study focuses on the analysis of the Southern Oklahoma Transpressional System (SOTS), a fault zone that extends from the southeastern Laurentian margin into the plate interior. The researchers utilize sedimentary thickness maps and seismic reflection data to reveal the kinematics and driving mechanisms behind the SOTS fault zones.
