Subduction is the main process that recycles surface material into mantle. Fluids and melts derived by dehydration partial melting reactions of subducted continental crust, a major reservoir volatiles (i.e., H 2 O CO ) incompatible elements, can substantially metasomatize refertilize Here, we investigate glassy inclusions silicate melt origin found in Variscan ultrahigh-pressure eclogites to assess crust contribution mantle metasomatism journey volatiles, carbon particular, deep roots...
Archean rocks of the tonalite-trondhjemite-granodiorite (TTG) suite are dominant constituents Earth’s earliest preserved silicic crust, while conversely rare in Phanerozoic continental crust. Their formation represents first critical step towards construction and preservation continents. Formation most TTG magmas involved partial melting hydrous, probably silicified, mafic at various depths (20–50 km, possibly up to 100 km). Many possible tectonic scenarios fit petrological geochemical...

Abstract The world-class San Rafael tin (-copper) deposit (central Andean belt, southeast Peru) is an exceptionally large and rich (>1 million metric tons Sn; grades typically >2% Sn) cassiterite-bearing hydrothermal vein system hosted by a late Oligocene (ca. 24 Ma) peraluminous K-feldspar-megacrystic granitic complex surrounding Ordovician shales affected deformation low-grade metamorphism. mineralization consists of NW-trending, quartz-cassiterite-sulfide veins...
Underexplored accessory minerals such as titanite and apatite have the potential to give insights into nature petrogenesis of their host rock.Their trace element REE-rich compositions carry a record crystallisation history chemical characteristics source.Moreover, and, certain extent, are resistant erosion during sedimentary cycles which makes them ideal reconstruct long-eroded continental landmasses.Here we report new data on from granitoids different Archean cratons comparative...
Abstract During its late‐stage evolution, the European Alpine orogen witnessed a northwest‐directed propagation of deformation front along an evaporitic basal décollement into foreland. This resulted in decoupling northern Molasse Basin from basement and formation Jura fold‐and‐thrust belt. Here, we present first absolute age temperature constraints on this using carbonate U‐Pb LA‐ICP‐MS dating clumped isotope thermometry. We analyzed calcite veins associated with thrust fault branching off...
Since the onset of plate tectonics, continents have evolved through a balance between crustal growth, reworking, and recycling at convergent margins. The term "reworking" involves re-insertion material into pre-existing volumes, while growth respectively represent gains from losses to mantle. Reworking that occurs in mantle wedge ("source" contamination slab material) or within upper ("path" contamination), will contrasting effects on evolution. However, due limited access deep rocks,...
