Fluid Flow Origin and Evolution of the Callovian–Oxfordian Carbonate in the Fold‐Thrust Belt in the Right Bank of the Amu Darya River, Northeastern Turkmenistan

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Complex fluid flow patterns can be triggered by tectonic forces generated during thrust emplacement along active margins in fold‐thrust belts and foreland basins. Isotope data (δ13C, δ18O, and 87Sr/86Sr), fluid inclusions, rare earth elements and yttrium (REEY), and U‐Pb dating of the calcite and saddle (Sd) dolomite veins are used to reconstruct the ...

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

open access: yesGeofluids, 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.

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]

open access: yes, 2011
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.

Application of Raman Spectroscopy in Oil and Gas Geological Research

open access: yesJournal 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

open access: yesApplied 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
