AbstractExposures of enclave-bearing granitoids can provide rare opportunities to directly evaluate the connection between compositional variability and the depth of origin of arc magmatic rocks. The ~1000 km long Gangdese batholith is a composite bath…
AbstractLong-lived collisional orogens that formed over tens to hundreds of millions of years are common in the geologic record. The Trans–North China orogen marks the collision between the Eastern and Western blocks of the North China craton, and it p…
AbstractFluvial-deltaic systems are subject to non-uniform backwater flow where rivers approach receiving basins. This hydrodynamic condition results in sediment aggradation on the channel bed and enhanced downstream fining. In turn, this impacts river…
AbstractThe formation of accretionary wedges with oversteepened slopes and uplifted axial zones has been demonstrated to be potentially associated with highly oblique plate convergence by numerical and analog studies. The direct role of this mechanism,…
AbstractThe timing of high-pressure (HP) metamorphism in the eastern Himalayan syntaxis is important for understanding the India-Asia collisional processes, but it remains elusive. To reveal the metamorphic history of the eastern Himalayan syntaxis, we…
AbstractAn immiscible two-phase model based on the incompressible Navier-Stokes (N-S) equations is used to simulate the air blast generated by an avalanche. For simplicity, the avalanche is treated as an assembly of monodisperse spherical grains and de…
AbstractThe origin of geological depressions abounding on Mars and other planetary bodies remains poorly understood, partially due to the limited variability in the geological settings of existing terrestrial analogs. Here, we present a new terrestrial…
AbstractJuxtaposition of different-grade metamorphic slices is a typical feature of Phanerozoic orogens but is relatively scarce in Precambrian orogens. Here, we focus on the Chengde Complex at the northern segment of the late Paleoproterozoic Trans-No…
AbstractThe India-Asia collision reactivated the early Paleozoic Qilian orogen with an intense metamorphic belt that promoted the release of metamorphism-generated radiogenic Sr into the drainage systems on the NE Tibetan Plateau. This metamorphic impa…
AbstractAccurate estimates of earthquake ground shaking rely on uncertain ground-motion models derived from limited instrumental recordings of historical earthquakes. A critical issue is that there is currently no method to empirically validate the res…
