摘要
乌拉山含金矿脉赋存于上太古界乌拉山群高级变质岩区，并受控于乌拉山断裂构造带。区内出露花岗岩体以及大量不同成因的长英质脉体。根据含金矿脉副矿物锆石的形态特征和微量元素（Ｈｆ，Ｕ，Ｙ，Ｔｈ，Ｐ）配分特征，推测锆石的形成以及所反映出的成矿流体具有酸性岩浆来源和基性岩浆来源的双重性成因信息。
The Wulashan gold-bearing ore veins are located within the high grade metamorphicrock area of Late Archean Wulashan Group and are controlled by Wulashan faulted structural zone. Granite massif and a number of felsic veins with several genetic types outcrop inthis area. According to the study on the morphological feature of the accessory zircon fromgold-bearing ore veins,and the partition feature of microelements (Hf, U,Y,Th,P),it can beinferred that the formation of zircon and mineralizaing fluid reflected by it have a dual natureof genetic information derived from both acid magma and basic magma.
