新疆东天山黄山东铜镍矿矿体分布规律探讨

摘要

HuangShandong rock mass is located in the middle of eastern Tianshan orogenic belt in Xinjiang, formed by four magma intrusion:the first invasion is mainly by hornblende gabbro, olive gabbro phase and diorite phase, forming the main body of the complex rock body in Huangshandong;The second invasion is mainly by the transitional gabbronorite;The third time intrusion mainly by plagioclase lherzolite;while the fourth intrusion formed only hornblende gabbro in the rock bottom. The industrial orebody in Huangshandong is hosted ore deposit mainly occurs in plagioclase lherzolite of the third invasion, followed by the first invasion of olive gabbro.%黄山东岩体位于新疆东天山造山带中部,由四次岩浆侵入形成:第一次侵入主要为角闪辉长岩相、橄榄辉长岩相及闪长岩相,本次侵入形成了黄山东杂岩体的主体;第二次侵入主要为过渡型的辉长苏长岩;第三次侵入主要为斜长二辉橄榄岩;第四次侵入仅形成了岩体底板的角闪辉长岩. 黄山东矿床的工业矿体主要赋存于第三次侵入的斜长二辉橄榄岩中,其次为第一次侵入的橄榄辉长岩中.
