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 ...

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
