大冶铁矿地质特征及成矿模式研究

The geological feature and metallogenic model study of Daye iron deposit

大冶铁矿主要产于燕山期闪长岩体南缘与三叠系灰岩的接触带上。通过其成矿地质背景,矿区地质特征以及矿床成因与成矿模式的研究探讨,建立了3种矿床模式,即矿浆贯入式、热液交代式及矿浆贯入—热液交代过渡式,并列举分析了3种模式分布的代表性区域。通过对大冶铁矿矿床成因模式的探讨,指导其后期外围及深部找矿勘查工作和区域找矿勘查部置。

Daye iron deposit basically originates in the contact zone of southern of Yanshanian diorite body and Triassic limestone. Three kinds of deposit models were established after discussing the metallogenic geological setting, geological characteristics, ore genesis and metallogenic type, which was the pulp injected, pyrometasomatic and pulp injection-pyrometasomatic transfer deposit, then the representative distribution regions of the three models were pointed out and analyzed. The results can provide some reference for the mine periphery and deep exploration and project layout.
