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.

Hydrocarbon charge history of deeply buried clastic reservoirs in the Bozi area of the Kuqa Depression, western China: implications for deep and ultra-deep petroleum exploration

Frontiers in Earth Science
Significant progress has recently been made in deep and ultra-deep oil and gas exploration globally, demonstrating enormous exploration potential of the deep and ultra-deep strata. However, the accumulation and preservation pattern of deep and ultra-deep

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, Volume 11, Issue 4, Page 1029-1062, September 2025.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

Structural Architecture of the Cenozoic Kallianos (Post‐?)Orogenic Vein‐Hosted Au‐Ag‐Te Deposit and Its Relationship to the North Cycladic Detachment System, Greece

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal‐scale detachment, the ...

Application of 3D Raman Mapping on Complex Inclusions: A Case Study of the Styrian Basin Mantle Xenoliths (W‐Carpathian Pannonian Region)

Journal of Raman Spectroscopy, Volume 56, Issue 7, Page 577-589, July 2025.
Recent advancements in spectral and spatial resolutions for Raman spectroscopy allow the analysis of fluid and melt inclusions. To explore the applicability of 3D Raman mapping, we conducted 3D Raman mapping on inclusions hosted by orthopyroxene in modally metasomatized mantle xenoliths from the Styrian Basin (W‐Carpathian Pannonian Region).

Pulsed Injections of Metal‐Rich Magmatic Fluids: Key Drivers of Mineralization in a Back‐Arc Basin Hydrothermal System

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Submarine magmatic–hydrothermal systems, where magmatic volatiles and fluids possibly serve as major sources of mineralization elements, have been extensively documented in numerous felsic‐hosted hydrothermal fields. Previous studies have primarily focused on the contribution of magmatic volatiles in such hydrothermal systems.
