Abstract:
By using La-Mc-ICPMC method, accurate zircon U-Pb dating has been made for volcanic rock samples from the Naocangjiangou Formation in the Xiugou basin of the East Kunlun orogenic belt. The zircons from the rhyolitic tuff (sample DG25-4) showed oscillatory girdles in its cathodeluminescence image, in...
EVIDENCE OF ZIRCON U-Pb AGES FOR THE FORMATION TIME OF THE EAST KUNLUN LEFT-LATERAL DUCTILE SHEAR BELT

2010, 16(1): 51-58.
Abstract (323) HTML (144) PDF (680KB)(4)
Abstract:
The large-scale East Kunlun left-lateral ductile shear belt was formed by an oblique collision between the Bayan Har-Songpan-Ganzi terrain and the southern East Kunlun terrain during the Late Triassic. During the Cenozoic, this ductile shear belt was transformed into a brittle leftlateral strike-sli...
