西安地质调查中心承担的国土资源大调查专项“北祁连错沟—寺大隆一带铜矿预测与评价”工作项目2000~2001年曾通过地质填图、电法、矿化标志等综合方法在北祁连大岔—大坂地区预测出纳木桥隐伏铜矿找矿靶区。2014年,民营矿业公司经硐探验证,已在该靶区的两个中段见到数米厚的块状硫化物型铜矿体。铜矿石具纹层状构造,围岩为奥陶系海相基性火山岩,表明为海底火山喷流成因。这些情况说明,西安中心采用的地质-物探综合方法对于预
Xi’an Geological Survey Center undertakes a large survey of land and resources special “North Qilian Ergou - Temple Dalong copper mine prediction and evaluation of” work projects from 2000 to 2001 through the geological mapping, electrical law, mineralization signs and other comprehensive Methods Predict the prospecting target of Naomuqiao buried copper deposit in the Dacha-Daban area in North Qilian. In 2014, private mining companies, after tunneling tests, saw massive deposits of several massive sulphide-type copper bodies in the two middle sections of the target area. The copper deposits are laminar and the surrounding rock is Ordovician marine base volcanic rocks, indicating the genesis of the submarine volcanic jet. These facts show that the integrated geological-geophysical method used in Xi’an Center is suitable for pre-treatment
