大冶摇篮山金矿地质特征和找矿远景分析

Analysis of Geological Characteristics and Prospecting Prospects of the Yaolanshan Gold Mine in Daye

摇篮山金矿位于长江中下游成矿带西端的鄂东南矿集区,与铜绿山铜铁(金)矿床紧密相连。在充分整合前人地质资料的基础上,对摇篮山金矿的成矿地质特征进行了系统研究,并总结其控矿因素。通过深入分析金矿的成矿机制和空间分布特性,总结出摇篮山金矿成矿模式,认为摇篮山金矿Ⅰ、Ⅱ号矿体成矿均与含矿热液及构造破碎带相关,其成因类型为中、低温热液-变质型;Ⅱ号金矿体北东向延伸部位以及矿区南部5~7线深部仍然有较大的找矿空间。

Yaolanshan Gold Mine is located in southeastern Hubei ore concentration area at the west end of the middle and lower reaches of the Yangtze River metallogenic belt,and is closely connected with the Tonglushan Cu-Fe(Au)deposit.On the basis of the full integration of previous geological data,the metal⁃logenic geological characteristics of the Yaolanshan Gold Mine are systematically studied,and the ore-con⁃trolling factors are summarized.Through in-depth analysis of the metallogenic mechanism and spatial distri⁃bution characteristics of the gold deposit,the metallogenic model of the Yaolanshan Gold Mine is summa⁃rized.It is believed that the mineralization of No.I and II orebodies in the Yaolanshan Gold Mine is related to ore-bearing hydrothermal and structural fracture zone,and its genetic type is medium-low temperature hy⁃drothermal metamorphic type.There is still a large prospecting space in the northeast extension of No.Ⅱgold orebody and in the depth of line 5~7 in the south of the mining area.
