Summary: Based on research methods for petroleum systems, this study analyzed the characteristics of source rocks, reservoir rocks, caprocks, and the process of hydrocarbon generation, trap evolution, and oil accumulation in the oil-bearing assemblage in the Shuangcheng area of the northern Songliao Basin, NE China. The source rocks are mainly found in the Cretaceous Yingcheng Formation (K1yc), with high-quality organic abundance originating from lower aquatic organisms and algae. The crude oil generated from the K1yc source rocks has low density, high freezing point, and high wax content. The reservoir rocks consist of K1d sandstones and K1yc glutenites, and the oil was accumulated during specific periods. The traps evolved in three stages, forming structural and structural-lithologic reservoirs. It is concluded that the favorable factors for oil reservoir formation include a good source-reservoir-caprock assemblage, late hydrocarbon charging, short migration distance, and stable tectonic setting.

Summary: The Songliao Basin in eastern China is the largest Mesozoic intracontinental nonmarine basin. It initiated as a backarc extensional basin in the latest Jurassic and experienced thermal cooling controlled subsidence in the early Late Cretaceous. The basin fill of the Coniacian-Maastrichtian period shows a retroforeland basin system, characterized by an increase in sediment thickness towards orogenic highlands, a shift in detrital provenance, and propagation of E-W shortened structures.

Summary: This study investigates the organic matter-rich intervals in the Cretaceous succession of the Songliao Basin in northeastern China and examines the influences of global and regional factors on organic matter accumulation. The analysis of well logs, drill cores, and geochemical data reveals higher salinity stratification and stronger anoxia in the Southeastern Uplift compared to the Central Depression. The research also suggests that two separate depocenters might have existed during the deposition of the lowermost and most organic-rich sub-unit. The study provides direct evidence that basin segmentation strongly controlled the distribution of organic matter-rich rocks in the Qingshankou Formation.

Summary: Alternative depositional models for the Early Cretaceous McMurray Formation are controversial. New detrital zircon U-Pb ages from 31 samples were analyzed to identify source terranes and estimate maximum depositional ages. The results indicate multiple source terranes within a paleodrainage basin and support the mixing of primary and recycled sources in the axial system of the McMurray Formation. The maximum depositional age of the McMurray Formation is estimated to be significantly younger than previously reported.

Summary: Stratabound base metal sulfide deposits in Fujian Province, China, are important Zn-Pb producers. The origin of the Pb-Zn mineralization has been debated, with conflicting ore genetic models proposed. In this study, U-Pb ages of hydrothermal titanite and C-O-S-Pb isotopes of gangue and ore minerals were analyzed to determine the timing and origin of the mineralization. The results suggest that the Shanhou deposit is a metasomatic skarn-like deposit associated with a possible hidden Early Cretaceous felsic intrusion at depth, rather than a metamorphosed VMS deposit.

Summary: There is a general relationship between the formation of terrestrial hydrocarbon source rocks and marine incursions during the Mesozoic-Cenozoic in China. This study focused on the little-studied Upper Cretaceous Qingshankou Formation in the Songliao Basin, China, and found that the formation contains mudstone and shale with high organic matter content, meeting the criterion of a very good-excellent source rock. Marine incursions triggered lake anoxia and increased primary productivity, improving the quality of the source rocks.

Summary: The evaluation of pore characteristics in lacustrine shales is important for shale oil and gas exploration. However, there have been limited reports on the quantitative evaluation of lacustrine pores due to complex depositional environments. In this study, experiments were conducted on lacustrine shale core samples to quantitatively characterize the pores. The results provide a reference for shale oil evaluation and complement studies on lacustrine pore characteristics.

Summary: Hybrid carbonates change with biological and environmental conditions throughout geological history. Organic reefs in the upper Moscovian-Kasimovian strata of Guizhou, South China, are composed of microbial carbonates, abiotic marine cements, and skeletal organisms, which are classified as triple hybrid carbonates. Petrographic features suggest that these reefs formed at a shelf margin or upper slope setting with active water circulation.

Summary: Recent studies focus on debates surrounding the involvement of northwestern China blocks, specifically the north Tarim block, south Tarim block (STB), Altyn Tagh block (ATB), and Qaidam-Qilian block (QQB), in the assembly of Rodinia. In this study, a combined paleomagnetic, geochronological, and geochemical investigation was conducted on 16 mafic dikes in the northern ATB. Three characteristic remanent magnetization components (CHs) were identified after removing recent viscous remanent magnetization. CH1, found in NW-trending diabase dikes, yielded a mean direction of 123.3°/-42.2° and a calculated paleopole of 40.9°S/184.6°E. CH2 and CH3 were isolated from E-W trending diabase dikes and lamprophyre dikes, respectively. However, precise mean poles could not be determined for CH2 or CH3 due to insufficient VGPs. Geochemical analyses also revealed petrogenetic discrepancies among the dikes with different CHs. Combining the new ~895 Ma pole of CH1 with the global paleomagnetic database and geological evidence, it is suggested that the STB-ATB-QQB and the north China craton were located northwest of Laurentia in Rodinia around ~895 Ma.

Summary: In this study, a cyclostratigraphic analysis of the Tieqiao section in South China was conducted to investigate the climatic and biological responses during the late Paleozoic icehouse-to-greenhouse transition. The results show that variations in gamma rays reflecting continental weathering strength are paced by Milankovitch cycles. It was found that increased marine speciation was associated with elevated climatic humidity when Gondwana land was minimally glaciated, but as the glaciation weakened and tropical aridification continued, arid conditions and marine transgression at obliquity nodes led to a decrease in marine biodiversity.

Summary: The SK01 sanidine was evaluated as a 40Ar/39Ar reference material through analysis in three different laboratories. The results showed that the heated samples from two laboratories yielded similar ages, with a weighted mean age of 27.58 Ma. Single-crystal step heating and single-crystal total fusion analyses were conducted in the third laboratory to test the intracrystalline homogeneity. This initial characterization of the SK01 sanidine provides valuable information for its potential use as a 40Ar/39Ar reference material, but further research is needed to evaluate its age dispersion.

Summary: Cyclostratigraphic analysis on magnetic susceptibility was conducted on geological sections in South China, revealing astronomically forced paleoclimate changes during the Middle-Late Ordovician transition. The thickness ratios of sedimentary cycles in the studied sections are consistent with Milankovitch cycles. Comparison of sedimentary successions between South China Block and Tarim Basin suggests a duration of approximately 1.38 million years for the Middle Ordovician gap in South China.

Summary: The Shin-Yan-Ny-Hu (SYNH) mud volcanoes in southwestern Taiwan are considered as typical subaerial mud volcanoes. The study investigated the lipid biomarkers and their stable carbon isotopes to understand the sources, depositional environments, thermal maturity, probable source strata, and migration framework of the volcanic fluid. The organic matter in the active SYNH mud volcanoes primarily originated from petroleum derivatives, bacteria, and terrigenous C3 plants. The results suggest a marine deltaic sedimentary environment with oxic conditions for the deposition of organic matter.

Summary: The Tuva-Mongolia collage system in the eastern Central Asian Orogenic Belt (CAOB) consists of the Tuva Block (TVB) and the Mongolia Block (MOB). The timing of their amalgamation was uncertain. By studying the andesitic Member 1 of the Baoligaomiao Formation, researchers found a U-Pb zircon age of 314.2 +/- 1.7 Ma and stable high-temperature components (HTCs) in paleomagnetic samples. The results, combined with previous studies, suggest that the TVB and MOB merged into a single entity around 315 Ma.

Summary: Establishing the temporal sequence of the Middle-Late Jurassic Yanliao Biota is crucial for understanding vertebrate evolution, but the lack of reliable and precise age data hinders progress. In this study, the authors propose a temporal sequence for the Yanliao Biota with precise age constraints, showing that the major vertebrate-bearing strata span from 164 Ma to 157 Ma in age. Incorporating this updated temporal framework into mammaliaform phylogeny reveals new insights into mammal evolution.

Summary: This study determines the Fe-Mn interdiffusion rates in natural Mn-bearing garnet crystals with 750 ppm H2O using an experimental approach. The results show that the Fe-Mn interdiffusion coefficient slightly decreases with increasing Fe content, and water significantly enhances the Fe-Mn interdiffusion in garnet. These findings suggest that the time required for homogenization of the compositional zoning of a garnet is much shorter than previously thought.

This study investigates the geochemical characteristics of Archean Mnformations in southern India and reveals the importance of these sedimentary deposits in understanding the ancient redox conditions and sedimentation patterns. The findings suggest that the sediments were deposited in shallow to deeper shelf environments in the Archean proto-ocean, and they provide evidence of regional episodes of ocean oxygenation prior to the Great Oxygenation Event.
