Structural preservation conditions analysis of oil and gas in complex structural area: A case study of structural analysis in the Well Wanjingdi-1, Anhui, China

Dizhi lixue xuebao, 2021
The multi-stage tectonism of compression and extension occurred in the southern part of the Lower Yangtze region in the Mesozoic, which is one of the important factors restricting the breakthrough of oil and gas exploration in this area.

Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, Volume 12, Issue 1, February 2026.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.

Iron–Phosphorus–Carbon Coupled Cycling in Lacustrine System of Ordos Basin During the Middle Triassic

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Widespread organic‐rich shales are associated with perturbations in productivity or preservation conditions; however, the major controlling factors, especially the phosphorus (P) and iron (Fe) interactions and their impacts on organic carbon burial in the paleolake ecosystem remain poorly understood.

Mineralization Characteristics of the Li‐rich Muscovite Granite in the Mufushan Batholith, Central China: Insights into the Rare Metal Mineralization Models of Batholithic Complex

Acta Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.
Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Formation process and controlling factors of tight buried-basement hill reservoirs:a case study of Weixinan Depression, Northern Beibu Gulf Basin, South China

Frontiers in Earth Science
In relatively stable sedimentary basins, the formation of buried-basement hill reservoirs mainly occurs after the basin basement forms and before the overlying sedimentary cover layer is filled. Represented by the Beibu Gulf Basin in the South China Sea,
