应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

In this his dissertation, the field geological work and modern analysis were finished on the Qulong ore-bearing porphyries. The mineralization chronology, petrology, element and isotopic geochemistry were studied on the porphyries. This dissertation also compare this work in Qulong ore-bearing porphyries with other ore-bearing porphyries in Gangdese belt, in order to probe into dynamical background and mineralization features of the ore belts in the condition of India-Eurasia collision.
