西秦岭花崖沟一带金矿找矿新进展

New progress of gold mineral prospecting in Huayagou area of West Qinling

为全力支撑服务新一轮战略性矿产国内找矿行动,“全国金矿重点调查区调查评价”项目围绕甘南—陇南金矿金资源基地建设,在甘肃李子园—花崖沟金矿重点调查区围绕石英脉型和构造蚀变岩型金矿开展调查评价工作。调查发现:九条沟—八卦庙地段金矿找矿潜力较大,区内中部花崖沟—大水沟一带发现一条矿化蚀变带以及余家塘、花崖沟西、麻地沟、大水沟4处矿点;其中花崖沟西经地表及钻探施工验证,估算金潜在资源量为10.88 t,具大型远景潜力。下一步将加强这一区域的综合研究,加大查证力度,开展深部验证,以期实现找矿突破,保障国家能源资源安全。

In order to fully support and serve the new round of domestic mineral prospecting action for strategic minerals,the authors in“national gold key investigation area investigation and evaluation”program focus on the construction of large-scale gold resource base around the Gannan-Longnan,and conducted investigation and evaluation work of quartz vein type and tectonic alteration type gold minerals in Gansu Liziyuan-Huayagou key investigation area.The gold prospecting potential in Jiuzhanggou-Baguamiao section is still large,and 1 mineralized alteration zone and 4 mining sites(Yujiatang,West Huayagou,Madigou,Dashuigou)are discovered in central part of Huayagou-Dashuigou.The estimated potential gold resources of West Huayagou is verified to be 10.88 t by surface and drilling construction,with large-scale prospect.The next step includes strengthening the comprehensive study of the area,enlarging investigation level and carrying out deep verification in order to realize a breakthrough in mineral prospecting and safeguard nation energy security.
