甘肃省响潭沟金矿矿床地质特征及找矿远景研究

Study on geological characteristics and prospecting prospect of Xiangtangou gold deposit in Gansu Province

甘肃省天水市响潭沟金矿位于李子园—太阳寺金银多金属成矿带东段,共发现金矿带1条,圈定金矿体4个。矿体受北东向断裂控制,矿体产于断层破碎带黄铁矿化构造角砾岩中,呈脉状、似层状产出,为中低温热液构造角砾岩型金矿床。矿床平均厚1.22~3.33 m,品位1.10~64.45 g/t,自然金呈似三角状不规则地分布于黄铁矿的裂隙中,中深部基本未封闭,资源远景有望达到中大型以上,显示出良好的找矿前景。

Xiangtangou gold deposit in Tianshui City,Gansu Province is located in the eastern section of Liziyuan-Taiyangsi gold silver polymetallic metallogenic belt.A total of one gold belt has been found and four gold ore bodies have been delineated.The ore body is controlled by the northeast trending fault.The ore body occurs in the pyritized structural breccia in the fault fracture zone and occurs in vein like and layered form.It is a medium and low temperature hydrothermal structural breccia type gold deposit.The average thickness of the deposit is 1.22~3.33 m and the grade is 1.10~64.45 g/t.The natural gold is irregularly distributed in the fissures of pyrite in a triangular shape.The middle and deep parts are basically not closed.The resource prospect is expected to reach above medium and large-scale,showing a good prospecting prospect.
