Findings of coesite and microdiamond in metamorphic rocks of supracrustal protolith led to the recognition of continental subduction to mantle depths. The crust-mantle interaction is expected to take place during subduction of the continental crust beneath the subcontinental lithospheric mantle wedge. This is recorded by postcollisional mafic igneous rocks in the Dabie-Sulu orogenic belt and it...

[1] Abstract: We present an integrated velocity field for the central Andes, derived from GPS observations collected between January 1993 and March 2001 that eliminates the velocity bias between the South America-Nazca Plate Project (SNAPP) and central Andes GPS Project (CAP) velocity fields published by Norabuena et al. [1998] and Bevis et al. [1999]. The reference frame is realized by minimiz...

The Central Asian Orogenic Belt (CAOB) is the world’s largest accretionary orogenic belt, and its formation related to closure of Paleo-Asian Ocean (PAO). However, time style PAO remain controversial. To address these issues, this paper presents zircon U-Pb dating, whole-rock geochemistry Lu-Hf isotope analyses volcanic rocks in Faku-Kaiyuan area on northern margin North China Craton. results s...
