Abstract Granitoids are the main constituents of continental crust, and an understanding their petrogenesis is key to origin evolution continents. Whether crystal fractionation dominant way generate evolved magmas has long been debated, mostly because such processes would produce large volumes complementary cumulates, which remains elusive. Mafic magmatic enclaves (MMEs) ubiquitous in granitoid...

The deep boundary and contact relationship between the Yangtze Cathaysia Blocks (the major tectonic units of Southern China Block), as well attributes Jiangnan Orogenic Belt, have remained unknown or controversial. Using data recorded by 128 portable broadband stations 96 permanent stations, we obtained high-resolution images crustal thickness Poisson’s ratio in study area. influences anisotrop...

We have compiled data on textures, trace element contents, Hf isotope compositions and U-Pb ages of zircons from lower crustal xenoliths the central part Columbia supercontinent in Precambrian areas North America, Siberia Northern Europe to address question when host rocks became continental crust. The time crust reached its current state, a layer high-pressure granulite-facies rocks, is dated ...

Abstract Strike-slip faults are widely developed throughout the Central Asian Orogenic Belt (CAOB), one of largest Phanerozoic accretionary orogenic collages in world, and may have played a key role its evolution. Recent studies shown that large number Late Paleozoic–Early Mesozoic ductile shear zones along southern CAOB. This study reports discovery NW–SE striking, approximately 500 km long up...

The arid interior of Asia is the largest source dust deposited in North Pacific Ocean, and some even transported to Greenland. Investigating provenance history Asian can provide strong constraints on evolution topography climate interior. Eolian Nd isotopic records preserved Ocean sediments since ∼40 Ma a spatially integrated first-order constraint changes dust. However, lack similarly long fro...
