Abstract The eastern Himalayan syntaxis in southeastern Tibet consists of the Lhasa terrane, High rocks and Indus‐Tsangpo suture zone. terrane constitutes hangingwall a subduction zone, whereas represent subducted Indian continent. Our petrological geochronological data reveal that has undergone two stages medium‐ P metamorphism: an early granulite facies event at c. 90 Ma late amphibolite 36–33 Ma. However, experienced only single high‐ metamorphic 37–32 It is inferred Late Cretaceous ( c ....
The Nyingchi complex, forming the eastern segment of Gangdese magmatic arc, occurs within southern Lhasa terrane in south Tibet, and is composed dominantly plutons their metamorphosed equivalents. Together with some metasedimentary units these rocks record multiple Mesozoic Cenozoic metamorphic events during northward subduction Neo-Tethyan oceanic lithosphere beneath Eurasian continent. Petrological geochronological studies reveal that complex experienced intense Paleocene...
The Nyingtri Group of the Lhasa terrane in southern Tibet consists dominantly metasedimentary rocks and orthogneiss. These have a similar mineral paragenesis plagioclase + K-feldspar biotite quartz ± sillimanite garnet staurolite muscovite amphibole, indicating amphibolite-facies metamorphic conditions. Inherited detrital zircons from show magmatic features yield widely variable 206Pb/238U ages ranging 3300 to 50 Ma. data define two prominent age populations, 1200–1000 600–500 Ma, that...
The formation and evolution of the basement rocks in Tibetan Plateau remain poorly constrained. Here we report petrology, geochemistry, zircon U-Pb geochronology orthogneisses, metamafic intrusions, metasedimentary from Amdo central Tibet. oldest Neoproterozoic (∼820 Ma) orthogneisses show chemical affinity to a volcanic arc setting. These rocks, together with coeval arc-magmatic belong an Andean-type setting traced Seychelles, Madagascar, western India, Lhasa, South China blocks, following...
Abstract The Gangdese magmatic arc, southeastern Tibet, was built by mantle‐derived magma accretion and juvenile crustal growth during the Mesozoic to Early Cenozoic northward subduction of Neo‐Tethyan oceanic slab beneath Eurasian continent. petrological geochronological data reveal that lower crust arc experienced Oligocene reworking metamorphism, anatexis magmatism after India Asia collision. post‐collisional metamorphic migmatitic rocks formed at 34–26 Ma 28–26 respectively....
Slab windows represent regions within the mantle that are largely devoid of slab material, facilitating direct communication between above and below subducting slab. This unprecedented interaction disrupts conventional material-energy exchange mechanisms subducted wedge, giving rise to anomalous heat flow, distinct magmatism, metamorphism, geophysical features. Geochemical analyses samples collected from southern margin Parece-Vela Basin have illuminated magmatic processes associated with a...
Abstract. We present a building damage dataset following the 2024 Noto Peninsula Earthquake. The database was compiled from freely available, multi-source, remote sensing data, verified through opt-in crowd-sourced information. consists of geo-referenced vector polygons representing pre-event footprints 140,208 structures. Each classified visual inspection using pre-disaster and post disaster vertical, oblique, survey, verifiable news reporting imagery. Entries were validated...
The Jiangzhuang ultrahigh-pressure (UHP) metamorphic peridotite from south Sulu, eastern China occurs as a layer within gneiss with eclogite blocks, and consists of coarse-grained garnet porphyroblasts fine-grained matrix assemblage + forsterite enstatite diopside ± phlogopite Ti-clinohumite magnesite. Both types are characterized by high MgO content depletion light rare earth element (LREE) enrichment heavy element, but the has lower MgO, TiO2 higher Cr2O3 REE contents. Diopside displays...
