The connection between the North China Craton (NCC) and contiguous cratons is important for the configuration of the Nuna supercontinent. Here we document a new Paleoproterozoic high-pressure (HP) complex dominated by garnet websterite on the northern margin of the NCC. The peak metamorphism of the garnet websterite was after ∼1.90 Ga when it was subducted to eclogite facies at ∼2.4 GPa, then e...

The high-pressure metamorphic Nevado-Filábride Complex (NFC) in the Betics mountain range of southeastern Spain exhibits continental and ocean-derived tectonic units, which are key for understanding geodynamic evolution Western Mediterranean. We address current debate definition emplacement (ultra)mafic rocks, timing burial metamorphism by conducting a structural study combined with single grai...

The high-pressure (HP) eclogites in the central Himalaya provide insights into metamorphism and exhumation history of crustal material beneath Tibetan plateau. Due to paucity exposure, nature timing protolith remain poorly known. Here we report zircon titanite U–Pb ages, bulk-rock mineral compositions Hf isotope data on from Thongmön Kharta areas Himalaya. record peak HP eclogite-facies at >1.6...

1. Introduction High-pressure minerals, produced by shock metamorphism, are common in and around melt veins in highly shocked chondrites [1-8]. These minerals either crystallized from silicate melt in the shock-vein or formed by solid-state transformed from host-rock fragments entrained in the melt or along shock-vein margins [3]. The study of these high pressure minerals can give us a better u...
