Modeling the Barite Deposition Process in the Jbel Irhoud Deposit, Western Jebilet, Morocco: Implications for Barite Exploration and Insights Into Mineralization Mechanisms

Geofluids, Volume 2025, Issue 1, 2025.
The barite of the Jbel Irhoud deposit in Western Jebilet, Morocco, is a Paleozoic massif known for its mineralization, which occurs mainly in shale, sandstone, and Middle Cambrian limestone. Three main types of barite deposits are known in the area: karst, vein fillings, and limestone replacement.

Application of Raman Spectroscopy in Oil and Gas Geological Research

Journal of GeoEnergy, Volume 2025, Issue 1, 2025.
Raman spectroscopy has shown considerable potential in the study of organic macerals in source rocks due to its significant benefits of accuracy, efficiency, and in situ nondestructive detection. This technology successfully applies to the reconstruction of paleotemperature and pressure environments, the quantitative evaluation of organic matter ...

Auriferous Fluid Evolution and the Role of Carbonaceous Matter in a Saddle‐Reef Gold Deposit: Dufferin Deposit, Meguma Terrane, Nova Scotia, Canada

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 12, December 2024.
Abstract The metaturbidite‐hosted, ∼380 Ma Dufferin gold deposit, Meguma terrane, northeastern Appalachian Orogen (Nova Scotia, Canada) is an orogenic gold deposit with mineralized saddle reef‐type quartz veins hosted by metasandstones and black slates in a tightly folded anticline. Together with native gold inclusions, genetically related hydrothermal

Tracing a Mantle Component in Both Paleo and Modern Fluids Along Seismogenic Faults of Southern Italy

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.
Abstract Aiming at understanding the source of the fluids that mineralizing within seismically active fault zones, we investigate the noble gas isotopes (i.e., helium (He), neon (Ne), and argon (Ar)) in the fluid inclusions (FIs) trapped in the calcite veins sampled along high‐angle fault zones of the Contursi hydrothermal basin, southern Italy.

Genesis of W Mineralization in the Caledonian Granite Porphyry of the Chuankou W Deposit, South China: Insights from Fluid Inclusions and C–H–O–S Isotopes

Applied Sciences
The Chuankou deposit is a super-large W deposit formed during the Indosinian collision event in South China, and its mineralization is suggested to be related to the Indosinian muscovite granite. However, two types of W mineralizations were discovered in
