TYPE AND ORIGIN OF THE CORE COMPLEXES AND THE DOMAL DEFORMATIONAL-METAMORPHIC BODIES IN THE WESTERN MARGIN OF YANGTZE CRATON

Hou Liwei(Sichuan institute of Geoloty and Mineral Resources,BGMS)  
According to the structure and origin, the domal deformational - mctamorphic bodies scattered in the western margin of Yangtze craton may be divided into four types:metamorphic core complex,magmatic core complex, gneiss dome and strucrual dome.Uplift in depth and extension near sruface, local magmatic activity and diapiric intrusion of syntectonic anatectic granite associated with local crustal uplift and extension were responsible for the magmatic and metamorphic core comlexes. The gnciss domes are attibutcd to partial melting and passive emplacement of bidirectional compressive setting.The structrual domes resulted from tectonic deformation and superposed deformation.They are different in space-time distribution and ore control. They were formed in different evolutionary stages and under conditions of different tectonic regime and setting during the orogenesis in the western margin of Yangtze craton.
