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.

Structurally Controlled Silica Precipitation Within Multi‐Stage Fault Damage Zones During the Rifting of the Pannonian Basin

Basin Research, Volume 37, Issue 3, May/June 2025.
Evolution of deformation mechanism and associated silica precipitation with respect to stratigraphic and burial position during syn‐rift phases. ABSTRACT Development of brittle fracture zones as passages for fluid migration within the shallow crust results in substantial petrophysical and rheological changes that strongly influence deformation ...

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

Hydrothermal Fluid evolution in the Dalli porphyry Cu-Au Deposit: Fluid Inclusion microthermometry studies

Journal of Economic Geology, 2015
Introduction A wide variety of world-class porphyry Cu deposits occur in the Urumieh-Dohktar magmatic arc (UDMA) of Iran.The arc is composed of calc-alkaline granitoid rocks, and the ore-hosting porphyry intrusions are dominantly granodiorite to quartz ...

Fluid Inclusion and Oxygen Isotope Constraints on the Origin and Hydrothermal Evolution of the Haisugou Porphyry Mo Deposit in the Northern Xilamulun District, NE China

Geofluids, 2017
The Haisugou porphyry Mo deposit is located in the northern Xilamulun district, northeastern China. Based on alteration and mineralization styles and crosscutting relationships, the hydrothermal evolution in Haisugou can be divided into three stages: an ...
