A discussion on prospecting direction in Gaojian tungsten-gold polymetallic mining area in Chongyang County,Xian'ning,Hubei Province
The Chongyang Gaoji tungsten and gold polymetallic mining area is located in the tungsten and gold polymetallic metallogenic belt in the middle and lower reaches of the Yangtze River.Although a lot of mineral exploration and scientific research work have been carried out in this area,no new progress has been made in the understanding of deep mineralization in this area.In order to explore the deep ore prospecting information in this area,the author has carried out work such as gravity and magnetic anomaly characteristics,CSAMT anomaly profile and wide-area electromagnetic profile.A positive gravity and magnetic low value anomaly was found in the south of Gaoview mining area,and the phenomenon of high resistance uplift in the resistivity of the deep anomaly of line 2 and line 3 was studied.It is inferred that the buried rock mass is distributed in the southwest of the study area,and its skarn contact zone is conducive to the enrichment of W element,which is a favorable location for searching skarn scheelite.It is speculated that there may be deep rock mass in Gaojian area,which should be located in the southwest of Gaojian.The regional spatial location shows that the dikes are most likely from Mufushan rock mass,and the two NE-trending faults form favorable migration channels for magma and mineral fluids.
