金厂沟梁金矿田“三位一体”成矿模式

Analysis of the"Trinity"metallogeny of the Jinchanggouliang Gold Field

金厂沟梁金矿田是内蒙古东部、辽宁西部地区著名的金矿田,其内金矿床为典型的薄脉型金矿床,矿体具有成群分布的特点,多受北西向、近南北向等构造控制,矿体类型以多金属硫化物型、蚀变岩型为主。结合多年的生产勘探成果,深入分析了成矿地质体、成矿构造及成矿作用,构建了金厂沟梁金矿田“三位一体”成矿模式,推测该矿田成矿地质体不单一,深部及边缘仍有较大找矿潜力,也可能存在新的成矿类型,可作为进一步找矿方向。

The Jinchanggouliang Gold Field is a renowned gold field in eastern Inner Mongolia and western Liaoning.The deposits in it are typical thin-vein type gold deposits and ore bodies are distributed in groups,mostly controlled by the NW and near SN structures.The ore body types are mostly polymetallic sulfide types and altered rock types.Many years’production and exploration achievements and in-depth analysis of the ore-forming geological body,ore-forming structures and mineralization constitute the basis to construct the"Trinity"metallogeny of the Jinchanggouliang Gold Field,which predicts the gold field has no single metallogenic geological body,that there are prospecting potentials deep and at the fringe,and that there might be new type metallogeny.These guide next-step prospecting.
