| 中文摘要: |
| 区内铜镍矿床的形成,直接与“安定型”基性岩性的含矿专属性有关,与岩浆分异程度、化学成分、侵入方式、分异的理化条件、岩浆期后矿化作用、接触交代作用有关。基性—超基性岩浆岩是区内铜镍矿床的母岩,通常有良好的分异现象。一般岩体边缘至中心可分成致密的辉绿岩相—中细粒橄榄辉长苏长岩相—中粒苏长辉长岩相—中粒闪长岩相。矿体产于岩体中下部,橄榄苏长辉长岩和苏长辉长岩是矿床的有利围岩,工业矿体主要产于含橄岩相带中。矿床成因属岩浆熔离贯入型铜镍矿床。 |
| 英文摘要: |
| The formation of Cu-Ni deposits of Weidong rock body directly related to the metallogenetic specialization of "Anding type" basic rock, such as, magma differentiation , chemical composition, pattern of intrusion, physical and chemical conditions of differentiation, postmagmatic mineralization and contact metasomatism. . The parent rock of mineralization of the deposits is the basic ultrabasic rock, which usually have obvious differentiation phenomena. From the outside of the rock body to the inner, the parent rock can be divided into compact diabase lithofacies, medium fine grained olivine gabbro norite lithofacies, medium grain norite gabbro lithofacies, medium grain diorite lithofacies. Orebodies are located at the middle-lower part of Weidong rock body, and the favorable wall rock for the ore deposits are olivine norite gabbro and norite gabbro, among which industrial orebodies mainly occurred in olivine-bearing lithofacies. The genesis of the deposit belongs to liquidation-type Cu-Ni deposit. |
