Zircon SHRIMP dating and its geological implications of the metamorphic rocks in Ailao Shan-Diancang Mountain Ranges, west Yunnan
滇西点苍山—哀牢山变质岩系锆石SHRIMP定年及其地质意义

Ailao Shan-Diancang Mountain Ranges,which are situated in the west part of Yunnan Province,are famous for their distinctive topography,geomorphology and geological structures.The principal part of Ailao Shan-Diancang Mountain Range is composed of high metamorphic rock series,which are considered as the Precambrian metamorphic basement of the Yangtze Plate. In this paper,U-Pb ages of zircons from granodioritic mylonite of Diancangshan Mountain (DCS-1) and biotite granodioritic gneiss of Ailaoshan Mountain (S...
