Summary: The Changning-Menglian Belt in the southeastern Tibetan Plateau is a major Paleo-Tethyan Suture that separates continental fragments from Gondwana and Eurasia. The volcanic rocks in this belt provide evidence of the tectonic processes during the evolution of the Paleo-Tethyan Ocean. New geochemical data for Early Carboniferous volcanics show that these rocks are magmatic cumulates with affinities to ocean island basalt.

Summary: This study proposed a new evaluation index for shale oil potential (SOPI) to assess the Permian Lucaogou shales in the southeastern Junggar basin, combining various methods including rock-eval pyrolysis, organic petrography, total organic carbon content, organic elements, vitrinite reflectance, and gas chromatography-mass spectrometry. The SOPI values were calculated using geochemometric methods and compared with previous evaluation parameters. The results showed consistency and revealed that the Qitai area has the highest shale oil exploration potential, followed by the Jimusaer, Miquan, and Mulei areas, while the Chaiwopu and Shiqiantan areas have the lowest shale oil potential.

Summary: This study assessed the potential of the Irati Formation shale layers in southeastern Brazil as sites for CO2 geological storage. Two potential shale gas reservoirs were identified based on organic geochemical parameters and petrography, and two locations were found to be more suitable for CO2 storage based on thermal maturity data. Therefore, a combination of organic chemistry and spatial analysis can be used as a guide to define reservoirs for CO2 storage in organic-rich shales within the Irati Formation.

Summary: Southeast Asia is affected by the superimposed effects of the Tethys and Pacific domains, resulting in complex deep structure, surface magma responses, and dynamic processes. This study reconstructs the dynamic processes of the Neo-Tethys Ocean closure and the formation of the curved subduction system in Southeast Asia. The remnants of the Neo-Tethys subducted slab and the Indo-Australian subducting slab in the mantle beneath Southeast Asia are coupled or decoupled depending on the specific subduction zone. The formation of the curved subduction system is the result of previous Neo-Tethys and current Indo-Australian Plate subductions and the westward subduction of the Pacific Plate. The opening of the North Australian Sea and the subsequent northward drifting of the Australian Block play a significant role in the geological history of Southeast Asia.

Summary: In December 2019, the Executive Committee of the International Union of Geological Sciences unanimously approved the proposal that the Global Stratotype Section and Point (GSSP) for the base of the Hauterivian Stage of the Lower Cretaceous be located at the base of bed no 189 of the La Charce section in Drome, southeast France. This level is identified by the first appearance of the ammonite genus Acanthodiscus, marking the base of the Acanthodiscus radiatus ammonite Zone, with additional data including 13 ammonite and nannofossil events, as well as magnetostratigraphic and carbon isotope events.

Summary: The study reconstructs the variations of water conditions in the Jafr Sub-basin resulting from climate changes by integrating data from geochemistry, clay mineralogy, and benthic foraminifera. Fluctuation of organic matter content and the response to nutrient fluxes are key factors, with indications of oxygen-depleted bottom waters and ecologically stressful surface waters. Warm-humid and warm-arid climatic conditions are linked to the preservation of organic matter and sulfur content.

Summary: This paper reports the first occurrence of the belemnite species Liobelus acrei in the Lower Cretaceous of the Vocontian Basin in southeast France. This finding revises the previously known spatial distribution pattern of boreal belemnites. The Valanginian belemnite assemblages in this area are dominated by genera of Tethyan ancestry, indicating an isolated immigration of boreal belemnites in the early Valanginian. The different distribution patterns shed new light on the ecology, migration patterns, and evolution of Early Cretaceous belemnites.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.
