Item description for The Proterozoic Glaucophane-schist Belt And Some Eclogites of North Yangtze Craton, Central China by Shenbao Dong...
This work deals mainly with the petrological, mineralogical and geochemical studies of the glaucophane-schist belts in the northern margin of the Yangtze Craton in Central China. It aims to highlight its petro-tectonic history through data thus far obtained. The glaucophane-schist belt extends about 2000 kilometres, and represents a bi-modal volcanism of Na-bearing volcanic series trapped within a sedimentary pile, showing a stratigraphic integrity, ranging from mid-late Proterozoic, with an ensialic crystalline basement and a superposed cover of the Sinian system. From the petrological evidence and geological context, it is suggested that the glaucophane-schist belt has originated as an intracontinental rifted mobile belt within the Yangtze Craton. Crustal rupture caused by rift-and-sag processes during the mid-late Proterozoic age led to the formation of high-pressure metamorphism which may be represented as a kind of intracontinental subduction during 600-800 Ma.
