河南省寺家沟金矿床地质特征及找矿方向

Geological characteristics and prospecting direction of Sijiagou gold deposit in Henan

河南省寺家沟矿区位于豫西崤山矿集区,矿体受太华群地层、NE向缓倾斜断裂构造和燕山期中酸性隐伏岩体的联合控制。矿床规模已达中型,但仍具有较大的找矿潜力,通过对矿床地质特征、成矿规律和找矿标志的总结,圈定了矿区进一步找矿的四个靶区。

Sijiagou gold deposit,lying inside Xiaoshan ore concentration area of western Henan,was jointly controlled by the formation of Taihua Group,the NE-trending gently dipping fracture structure,and Yan-shanian intermediate-acidity concealed rock bodies.The scale of the deposit reached medium-size,yet with a relatively great prospecting potential.After the study on geological characteristics,metallogenic regularity and clues for prospecting of the deposit,this paper delineated four blocks of target area for future prospec-ting.
