摘要

牛毛泉东金矿区位于甘肃省肃北蒙古族自治县,通过对该矿床成矿地质背景、矿床地质特征的分析,认为脆韧性剪切作用为牛毛泉东金矿最主要的控矿因素。矿体分布在近东西向脆韧性剪切带控制的黄铁绢英岩化带中,并严格受其控制。本文系统总结了牛毛泉东金矿的地质特征、成矿条件、分析了矿床的成矿模式。通过论述初步认为该矿床是脆韧性剪切构造控制的中低温热液型金矿床。
        The east of niumaoquan gold mining area is located in SuBei Mongolian autonomous county in gansu province, based on the analysis of metallogenic geological background, ore deposit geological characters of the deposit, and think the brittle ductile shearing action for ox hair springs east mine the main ore-controlling factors. The ore body is distributed in the yellow iron sericite belt controlled by the brittle ductile shear zone in the near east and west, and is strictly controlled by it. In this paper, the geological characteristics, metallogenic conditions and metallogenic model of the deposit are summarized. It is concluded that this deposit is a medium and low temperature hydrothermal gold deposit controlled by brittle ductile shear structure.
