通过对叶城－狮泉河剖面花岗岩中黑云母４０Ａｒ－３９Ａｒ法年龄研究，获得西昆仑北岩带库地岩体海拔高度２９５０ｍ和２８５０ｍ黑云母的封闭年龄分别为３９６．９Ｍａ和３８８．９Ｍａ，西昆仑南岩带塔西土路克、三十里营房和奇台大坂岩体黑云母的封闭年龄为１９５．８～１８３．９Ｍａ，班公湖－喀喇昆仑北岩带日土岩体黑云母封闭年龄为８０．３～７９．６Ｍａ，其时代分别为加里东期、印支期和燕山晚期。年龄结果表明，同一岩体海拔高的黑云母封闭年龄大于海拔低的黑云母封闭年龄，根据海拔高程差和坪年龄差计算出岩体的抬升速率，表明青藏高原西部从加里东期到燕山晚期，隆起速度有增大的趋势，而且具脉动性。
By studying the age of 40Ar-39Ar dating of biotite in the Yecheng-Shiquanhe granite, the sealing ages of 2950m and 2850m biotite rock masses in the northern Kunlun North Rocky Belt are 396.9Ma and 388.9Ma respectively, The sealing age of Tashiurugu, Sanshili barracks and Qitai Dabanite biotite in the Kunlun Nanyan area is 195.8 ~ 183.9Ma. The sealing age of the biotite rock block in the Bangonghu-Karakorum northern belt, For the 80.3 ~ 79.6Ma, its era were Caledonian, Indosinian and late Yanshan. The age results show that the age of closure of biotite in the same rock mass is higher than the closure age of biotite in lower altitudes, and the rate of uplift of rock mass is calculated according to the difference of elevation and pitting ages. It indicates that the rock mass elevation rate is from western Caledonia to late Yanshan , The rising speed has an increasing trend, but also pulsatile.
