中文摘要: |
老王沟矿区位于河南省栾川矿集区的西南部,周边矿权密集,成矿地质条件优越。在区内开展了1∶1万土壤地球化学测量,共圈定了8处综合异常。采用化探剖面、激电中梯和槽探等综合手段进行异常查证,在综合异常TR05内发现了与断裂F4有关的铅矿化体;综合异常TR07和TR08与激电中梯高极化率低阻异常套合较好;综合异常TR07开展了岩石地球化学剖面测量,在断裂构造F7处见Zn、Pb、Mo和W高值异常,经槽探工程验证发现了锌矿体。结合区域成矿地质条件和物化探信息,推测老王沟矿区具有较好的找矿前景。 |
英文摘要: |
Laowanggou mining area is located in the southwest of Luanchuan ore concentration area in Henan Province, with dense mineral rights and superior metallogenic geological conditions. A soil geochemical survey of 1∶10000 was carried out in the area, and a total of 8 comprehensive anomalies were delineated. The comprehensive means of rock geochemical exploration profile, IP intermediate gradient and trenching were used for anomaly verification, and lead mineralization related to fault F4 was found in the tr05 comprehensive anomaly; The comprehensive anomalies of TR07 and TR08 are well matched with the IP intermediate gradient anomaly with high polarizability and low resistance; The rock geochemical profile survey was carried out for TR07 comprehensive anomaly, and high value anomalies of Zn, Pb, Mo and W were found at F7 fault structure. The zinc ore body was found through the verification of trenching engineering. Combined with the regional metallogenic geological conditions and geophysical and geochemical exploration information, it is speculated that the prospecting prospects in the Laowanggou mining area are better. |
