大冶铁矿控矿构造研究及深部隐伏矿体定位预测

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。本文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4000×104t。

Investigation of Ore-Controlling Structures and Orientation Prognosis of Deep Concealed Ores in Daye Iron Mine

The main ore body of Daye iron mine extended along the contact faults zone,which was the primary ore-controlling structure in Daye iron mine,between the Yanshanian diorite and marble and dolomite-marble of Lower Triassic Daye Formation.This paper mainly deals with the types of ore-controlling structures and their space distribution,the features and occurrence of contact zone,the relations between the contact zone and metallization,as well as the emplacement mechanism of ore formation in Daye iron mine.It is estimated 40 million tons iron resource will be discovered in deep area in Daye iron mine.
