摘要:Abstract(#br)The recently discovered Çataldağ Metamorphic Core Complex (ÇMCC) of Eo-Oligocene age is situated in NW Turkey, which is a part of the Alpine collisional belt. The footwall of the ÇMCC consists of a granite-gneiss-migmatite complex (GGMC) with a domal structure. ...

摘要:Abstract(#br)Elucidating the composition of primary kimberlite melts is essential to understanding the nature of their source, petrogenesis, rheology, transport and ultimately the origin of diamonds. Kimberlite rocks are typically comprised of abundant olivine (~25–60 vol%),...

摘要:Abstract(#br)The large amount of geochemical variability in peridotitic and pyroxenitic xenoliths exhumed by Eocene to present-day magmas in Patagonia provides a unique opportunity to investigate the depletion and enrichment processes affecting the lithosphere in proximity o...

摘要:Abstract(#br)We have investigated the origin of garnet in garnet-spinel peridotite mantle xenoliths from two well-known localities, Pali-Aike (Patagonia) and Vitim (Siberia). We used micro-CT scanning to examine the textures of garnet-spinel clusters and the relationship between ...

摘要:Abstract(#br)Large quantities of continental lithosphere are known to enter the mantle during continental rifting, but their possible contribution in the generation of melts under a nascent ocean remains enigmatic. Here we report new in situ chemical and Sr Pb isotopic data ...

摘要:Abstract(#br)Late Cretaceous mantle peridotite of the Birjand ophiolite (eastern Iran) contains variably serpentinized and carbonated/listvenitized rocks. Transformation from harzburgite protolith to final listvenite (quartz + magnesite/± dolomite + relict Cr-spinel) reflect...

摘要:Abstract(#br)Iron formation-bearing sequences from the Guanhães Tectonic Block and Southern Espinhaço Belt of the Southeastern São Francisco Craton, were affected by the Ediacaran-Cambrian Brasilian Orogeny, when the Guanhães Block was upthrusted onto Statherian metasediment...

摘要:Abstract(#br)The Pacific plate since the Mesozoic is subducting into the mantle beneath the eastern Asia, and the involved recycled crustal material has greatly affected the mantle geochemistry. However, the initial timing of the subduction remains controversial, partly due ...
