Prospecting Prospect Evaluation For Silver(Polymetallic)Forecast Areas in Lanhualing and Its Periphery
The metallogenic geological conditions of the Lanhualing silver deposit has been analyzed in detail:the strata where silver and gold are hosted on the two wings of the Lanhualing anticline,the ore-controlling structure and the magmatic hydrothermal metal-logenic environment are extremely superior.The strata exposed are the second and third members of the Dashiqiao Formation and the Gaixian Formation of the Liaohe Group.Geochemical conditions:A total of 22 gold element anomalies,14 silver element anomalies,10 lead element anomalies and 24 arsenic element anomalies have been found,and four element combination anomalies distributed in the northwest direction have been delineated.Geophysical conditions:Three induced polarization anomaly belts have been obtained,which coincide with the interlayer fracture zone.Geological preliminary survey results:Three ore(mineralized)belts have been discovered,and five silver ore(mineralized)bodies have been discovered.Based on this,the prospecting prospects of the peripheral predicted area are evaluated.
