T52. Origin and evolution of ophiolite suites and their mineralization: an interdisciplinary approach

Ophiolites are important sources of information on the genesis and evolution of the oceanic lithosphere, from active spreading centers to subduction zones.
They record igneous features essential to understand primary processes of the upper mantle and ocean crust, and are affected by fluid-rock interactions at multiple stages, contributing to the geochemical cycles of volatiles and other elements (CO₂, H₂O, CH₄, Mg, Ca, etc.). Additionally, their meso- to micro-structural features are essential for paleogeographic and paleostructural interpretations and are useful tools to understand similar active geodynamic settings. Several economic ore deposits are also associated to ophiolitic sequences, such as chromitites, Platinum Group Elements (PGE) mineralization, volcanogenic massive sulfides and magnesite deposits.
This session seeks contributions addressing petrology, geochemistry, mineralogy and geotectonic evolution of ophiolite suites, including studies with a focus on ore formation.
