Abstract (229) HTML (110) PDF (1085KB)(11)
Abstract:
Caledonian movement is a very important tectonic deformation stage since the Early Paleozoic in Qilian. The most intense tectonic activity began to emerge between the late Silurian and Early Devonian. The granitic intrusive began to emerge in early Caledonian movement. To the late Caledonian movemen...
ESR AGES EVIDENCES OF MOHE OVERTHRUST STRUCTURE STAGE
LIU Xiao-jia, ZHAO Li-guo, TIAN Jun, YANG Xiao-ping, ZHANG Wen-long, GAO Xue-mi
2014, 20(3): 299-303.
Abstract (231) HTML (86) PDF (892KB)(12)
Abstract:
The 10 different structure quartz veins and calcite veins from Mohe basin overthrust structure root zone, the central belt and front belt has been dated by electron spin resonance (ESR). ESRS dating results show Mohe basin overthrust structure formed in (149.3±14.0) Ma~(118.7±11.0) Ma, which indicat...
