Abstract This contribution provides insights into ocean-floor hydrothermal metamorphism of the fast-evolving Dinaridic Neotethys. Mineralogical, geochemical and Sr isotope data collected from altered ophiolites non-ophiolite basalts/andesites tuffs active continental margin are consistent with alteration trajectories that reflect host-rock composition. suggests fluxes were restricted within a s...

Ophiolites are widely studied to unravel how new subduction zones form. They may contain crustal and mantle rocks that formed during juvenile stages of intra-oceanic subduction, modifying the pre-existing oceanic lithosphere within which started, in a magmatic arc upon maturation. Previous geochemical work on Cretaceous Andaman Ophiolite its metamorphic sole, located forearc Sunda zone south-ea...

The Andaman and Nicobar ophiolites, in the forearc of western Sunda subduction zone, underwent enigmatic, rapid Cenozoic vertical motions: shallow-water sediments with abundant arc debris characterize middle Paleocene–middle Eocene are under- overlain by significantly deeper sediments. Recent paleomagnetic results revealed a near-equatorial paleolatitude West Burma Block associated at similar l...

Abstract New trace-element, radiogenic Sr-Nd-Pb isotopic and geochronological data from Middle-Late Cretaceous Zagros ophiolites of Iran give new insights into the tectono-magmatic history these supra-subduction zone (SSZ)-type ophiolites. The distribution SSZ-type in comprises two parallel belts: (1) outer ophiolitic belt (2) inner belt. These were generated by seafloor spreading what became f...
