摘要

摘要: 作者在广泛收集前人资料的基础上,通过课题研究工作,剔除了一些地点、岩性、测试不详及方法不系统的年龄数据,获得了一组有价值的同位素年代学数据。它们可以代表目前北祁连山西段同位素年代学研究的主要成果与认识,对研究本区盆地-构造-岩浆-热事件提供了重要成因信息。综合评价这一成果,方法较全面,数据有一定系统性,从而有力地支持了对本区各类地质体形成与演化的认识,解决在北祁连山西段科研、地质找矿以及区域地质调查中一些长期争议的地层时代问题,对推动本区成矿时代、热历史等问题研究的深入,有重要意义。

Abstract: On the basis of carefully studiying on isotopic dating in the western part of the North Qilian Mountains, a lot of valuable isotopic data which could be considered as representatives were selected. It is concluded from these data that the general research degree is low in isotopic dating and that they are of great significance both in the determination of ages of all the geologic bodies concerned and in the settling upon of the ages of stratum and ore-forming and geologic hot events which have been quarreled in geologic scientific research,ore prospecting and regional geologic survey for a long time.
