摘要: 本文对喀喇昆仑—昆仑山地区三十里营房一带花岗岩类进行了Rb-Sr黑云母等时年龄研究,三十里营房闪长岩,Rb-Sr黑云母等时年龄为539Ma,属于寒武纪。赛图拉西花岗闪长岩Rb-Sr黑云母等时年龄为215Ma,相当于晚三叠纪。结果还表明在晚古生代公格尔-阿克阿卡孜岩帝中,存在早古生代花岗岩类。

Abstract: This paper deals with the Rb-Sr biotite isochron ages of the granitoid in the Sanshiliying-fang area of the Karakoram and Kunlun Mts. region. It has peen found that the Rb-Sr biotite isochron age of the diorite is 539 Ma, belonging to the Cambrian period, and that the Rb-Sr biotite isochron age of the Saidulla granodiorite is 215 Ma, being equivalently of the late Trias-sic period. The results also show that there exists the granitoid of Early Paleozoic Era in the Gonggol-Akagazi petrographical belt.

Key words: Sanshiliyingfang, granitoid
