新疆北山启鑫铜镍矿床地质特征

The Geology Features of Qixin Cu-Ni sulfide deposit in Beishan,Xinjiang

启鑫基性-超基性岩体是最近发现的铜镍矿化岩体。该岩体主要由辉长岩、二辉橄榄岩、橄辉岩、橄长岩、辉石岩等组成,岩石具多期侵入特点;区内已发现多处铜镍矿体,赋存于橄辉岩和辉橄岩相及后期延构造薄弱带贯入的较富的脉状铜镍矿体,矿体中金属矿物以镍黄铁矿、磁黄铁矿、黄铜矿、黄铁矿为主。本区铜镍矿成矿地质条件好,区内已探求333镍金属量2.69万吨,已达中型矿床规模,具有极好的寻找超大型镍矿床前景。

Qixin basic-ultrabasic rock body is a copper-nickel mineralizationg rock that was recently discovered.The rock is mainly composed of gabbro,lherzolite,throws pyroxenite,troctolite,pyroxenite and other components,it has amulti-phase emplacement characteristics. In this region,several copper and nickel ore bodies have been found. The more rich vein copper and nickel minerals, which are deposited in the phase of the oliveite and the pericite facies and the later dilatation structure. Metal minerals mainly have nickel pyrite, pyrrhotite, chalcopyrite, pyrite. The geological conditions of Cu-Ni ore in this area are good, The area has been searching for 333 nickel metal for 2.69 million tons. The scale of the medium size deposit has been reached, The prospect of super large nickel deposit is excellent.
