Rock‐buffered versus fluid‐buffered geochemistry of structurally controlled, hydrothermal dolomite: Insights from the Sichuan Basin, China

Sedimentology, Volume 72, Issue 7, Page 2087-2120, December 2025.
ABSTRACT Structurally controlled hydrothermal dolomitization, commonly driven by high‐pressure, high‐temperature fluid–rock reactions, offers insights into the tectonic evolution of sedimentary basins and the geochemical composition of their diagenetic fluids.

Tracking Sediment Mixing Along the Lower Danube River From the Carpathians to the Black Sea

Terra Nova, Volume 37, Issue 6, Page 413-420, December 2025.
ABSTRACT We use detrital zircon U–Pb geochronology as a sediment provenance tracer in modern river sands to better understand how tectonic, climatic, and anthropogenic processes modulate sediment transport dynamics of the Carpathians to the Black Sea source to sink system.

Correlation characteristics and genetic mechanisms between lithofacies and mechanical properties of deep carbonate rocks

Shiyou shiyan dizhi
To deeply analyze the intrinsic relationship between lithofacies characteristics and the mechanical properties of deep carbonate rocks, the study focuses on the Ordovician Yingshan Formation in the Tahe area of the Tarim Basin.
