对可可西里带西段卧龙岗二长花岗斑岩岩体进行锆石SHRIMPU-Pb年龄测定,获得212.5Ma±3.6Ma的岩体结晶年龄。认为黑石北湖-三道河子岩浆岩带经历了晚三叠世同碰撞造山作用。
SHRIMPU-Pb dating of zircons from the Wolong Kong granite porphyry in the western part of the Hoh Xil fault zone was carried out to obtain a rock age of 212.5 Ma ± 3.6 Ma. It is considered that the Beihu - Sandaohezi magmatic belt in Blackstone experienced the same orogenic collision during the Late Triassic.
