Plain Language Summary The rarity of earthquakes despite strong deformation in the deep crust of mountain belts produced by continental collisions, such as the Himalayas, implies that the deep continental crust is rather weak, easily dissipating imposed stresses by ductile deformation. The major components of the orogenic lower crust are plagioclas...

The crust of southern Tibet shows strong azimuthal and radial seismic anisotropies. However, their origin has remained ambiguous. Here we characterized the composition, microstructure, and seismic properties of amphibole-rich deep-crust xenoliths and exhumed rocks from a deep-crust terrane in southern Tibet. The xenoliths show typical magmatic text...

The bulk composition of overthickened Tibetan deep crust has been generally believed to be mafic granulite with eclogite at the lowermost crust. However, a granulitic/eclogitic deep crust is in contradiction to geological and geophysical observations in southern Tibet. Here we present petrofabrics and seismic properties of amphibolites from exhumed...

Adakite‐like potassic rocks are widespread in postcollisional settings where they provide potential insights into deep crustal processes that include partial melting, lower crustal flow and thickening, plateau uplift, and the creation of porphyry metal deposits. Although substantial progress has been made in characterizing the geochemical and geoph...

Geophysical and geochemical data suggest that garnet amphibolite might be an important rock type in the lower crust of the Tibetan plateau. Previous results on the rheology and deformation mechanism of amphibolite have been controversy. We report here preliminary axial deformation experiments on the rheology and fabrics of a reconstituted fine-grai...

We have investigated the lattice preferred orientation (LPO), water content, and seismic properties of the jadeite-quartzite from the ShuangHe (SH) area, Dabie mountains, eastern China using electron backscatter diffraction (EBSD) and Fourier transform infrared spectroscopy (FTIR) techniques. In addition, jadeite-K-feldspar-phengite orthogneiss fro...

In order to find the relationship among a large (Ms≥7) earthquake, or a giant earthquake (Ms≥8) and the steepest gradient of gravity field and active fault, the free air gravity anomaly map by EIGEN-6C gravity model was calculated, the bouguer gravity anomaly and active fault of the region trends to occur large or giant earthquake is consulted. The...
