| 摘 要： | 西藏冈底斯带东段的岗讲铜钼矿床产于复式岩体中,岩体主要由二长斑岩、英安斑岩和流纹斑岩类岩石组成,其岩性属于钙碱性系列岩石。岩石地球化学特征表明该复式岩体可能形成于碰撞后抬升期,矿化与低温低压的岩浆结晶分异环境有关。

| Abstract: | Gangjiang Cu-Mo deposit occurs in a complex rock body consisting mainly of monzonitic porphyry, dacitic porphyry and rhyolitic porphyry. The porphyries belong to the calc-alkaline rock series. Their geochemical characteristics indicate that the complex rock body may be formed in the post-collision uplift period and the mineralization is related to crystal differentiation under low-temperature low-pressure condition of magma. |
