摘要
大冶铁矿主矿体分布于燕山期闪长岩与下三叠统大冶群大理岩和白云质大理岩接触断裂复合带,该接触带是大冶铁矿矿床的主要控矿构造。文章对矿区接触带控矿构造类型及其空间分布特征、接触带形态产状特征及其与成矿的关系、成矿定位机制等作了比较系统的阐述,预测矿区深部可新增铁矿资源量4000万t。
The main ore bodies of Daye iron mine are distributed along contacting zones and faults between Yanshanian granite and later Triassic Daye formation of marble and dolomite - marble. The contacting zones are primary ore - controlling structures in the mine. Types of ore - controlling structures, space distribution of structure, occurrences of contacting zones, relations to mineralization, and ore orientation mechanism in the mine are discussed. It is predicted that 40 million tons iron resource can be discovered in deep area in the Daye iron mine.
