Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Mineralogical and Geochemical Characteristics of the Gudang Handak Vein Group in the Pongkor Au‐Ag Deposit, West Java, Indonesia

Resource Geology, Volume 76, Issue 1, January/December 2026.
The microtextural variations of quartz, which range from granular to feathery and microcrystalline forms, show a clear correlation between quartz geochemistry and gold grade, revealing that specific quartz textures are closely associated with higher gold concentrations in the Gudang Handak vein samples.

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.

Terrestrial Temperature Variability and Its Impact on Vegetation and Moisture Dynamics During Dansgaard‐Oeschger Event 22 in Northern Mexico

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Quantitative proxy records of past temperatures remain critically missing in northern Mexico. Here we present a new record of terrestrial temperature, hydroclimate, and vegetation variability during Dansgaard‐Oeschger (DO) Event 22, a millennial‐scale warming event, using a stalagmite from northern Mexico.
