摘要
通过对重磁场特征及已有地质资料综合分析,推断出石头肯德地区8个基性-超基性杂岩体,重新划分了区内的断裂构造、岩体分布。重力高、磁力高为石头坑德铜镍多金属矿识别赋存铜镍矿体的基性-超基性杂岩体的重要标志,赋存铜镍矿体的基性-超基性杂岩体分布明显受断裂控制。
Based on comprehensive analysis of the characteristics of gravity and magnetic field and the existing geological data, eight basic and ultra-basic complexes in Shitoukende area are inferred, and fault structures and rock mass distribution in this area are repartitioned. The important symbols to identify the basic-ultrabasic complex containing copper-nickel ore bodies are high in gravity and high magnetism in Shitoukende area, and the distribution of the basic-ultrabasic complex that contains copper-nickel ore bodies are controlled by fractures.
