Fluid Flow, Mineralization and Deformation in an Oceanic Detachment Fault: Microtextural, Geochemical and Isotopic Evidence From Pyrite at 13°30′N on the Mid‐Atlantic Ridge

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 1, January 2024.
Abstract Hydrothermal fluids in ultramafic‐hosted hydrothermal systems associated with oceanic detachment faults can be more oxidizing compared to mafic‐hosted vent sites. These fluids form a mineral assemblage of pyrite, magnetite and hematite. At 13°30′N on the Mid‐Atlantic Ridge, chlorite‐quartz breccias recovered from an exposed fault scarp contain

Sources of ore fluid components in IOCG deposits

, 2020
Many diverse hydrothermal copper deposits containing iron oxides are classified as IOCG deposits. Genetic models need to consider a number of different ore fluid components that may not all have the same source in an individual ore system, and also that ...
