红旗岭矿区老七号岩体底部成矿分析

Analysis of ore-forming probability under old No.7 rock mass of Hongqiling deposit

红旗岭矿区Ⅱ岩带的老七号岩体位于矿区的中部,并侵位于NW向断裂带。NW向的构造大致分为三大容岩主构造,这三大构造划分了3个岩带,I岩带为该区主要成矿区;第Ⅱ岩带是老七号岩体赋存的地带,如果在老七号岩体的底部发现具有工业价值的铜镍矿床,将是老岩体找到铜镍矿的一个重大突破;第Ⅲ岩带的岩体是不含矿的岩体。铜镍矿化体的形成还将受到岩体岩相以及成矿时期和所在地质环境的制约。

The old No. 7 rock mass is located at the middle of Ⅱ rock zone of Hongqiling deposit,and it intruded into NW trending fault zone. NW structure is roughly divided into three main containing rock structures, and these structures are divided into three rock zones. Rock zone I is the main metallogenic province. Rock zone Ⅱ is the occurrence zone of old No. 7 rock mass. If we can find valuable copper-nickel deposit at the bottom of old No. 7 rock mass, it will be a major breakthrough of ore prospecting in old rock mass area. Rock zone Ⅲ is a ore-free zone. The formation of copper-nickel ore body is also constrained by rock facies, mineralization period and geologic environment.
