摘要
野马泉金矿产于志留系库布苏群浅海—次深海相含火山碎屑的泥砂质沉积建造中,含矿围岩为破碎蚀变的闪长玢岩脉,矿带长约20km,矿体沿走向呈透镜状或脉状,断续分布,矿化受构造及岩体联合控制。主成矿期发生于脉岩形成后的构造破碎及岩石蚀变阶段,矿床为构造蚀变岩型金矿床。
The Yemaquan gold deposit occurs in arenaceous sedimentary formations with volcanic clast of neritic-hypoabyssal facies of Silurian Kubushu group. Diorite porphyrite dike is the wall rock of the gold deposit, whose ore belts is approximately 20 kilometers long, and the orebodies appear as podiform or nervation along the strike discontinuously. Mineralization of the gold deposit is jointly controlled by structure and rock body. The structure breaking up and rock alteration stage after dike rock formation is the main metallogenic epoch. The genesis type of the gold deposit is structure alteration rock type.
