Analysis Of Metallogenic Potential In The Southern Part Of The Weibao Pb-Zn Deposit

The Weibao Pb-Zn deposit is located at the junction of the active belt and the South China plate at the southern edge of the western plate.It is the Qinling-Kun mineralization zone-kunlun metallogenic province-East Kunlun Fe-Pb-Zn-Cu-Co-Au-W-Sn-asbestos-salt.The type is Lamellar skarn-type Pb-Zn deposits found in the metallogenic belts Weixi were discovered in the northwest direction by the subsequent exploration.Based on the characteristics of the Lamellar skarn-type deposits and the actual conditions of the Weibao Pb-Zn deposit,it is speculated that there are undiscovered orebodies on the eastern side of Weibao.This paper takes Weibao Pb-Zn deposit as a typical deposit,analyzes the regional geological features based on the systematic collection of previous data,determines the tectonic order,and summarizes the Pb-Zn ore-forming rules and ore-prospecting signs of the region.It comprehensively considers the Weibao Pb-Zn deposit.The ore-bearing strata are the Langyashan Formation in the Jixian Formation.The ore-controlling faults are northwest-facing faults,and the orebodies associated with the orebodies become lacquer,skarn,silicified,and limonite,which can be viewed from remote sensing images.Extract relevant geological information as a basis.After the ASTER and Landsat-8 data were preprocessed,human-computer interaction was used to perform visual interpretation;iron staining,silicification and carbonate radical alterations related to mineralization alterations were extracted by using the ratio method;and thermal infrared remote sensing technology was used.The relative contents of the four oxides of SiO₂,Al₂O₃,CaO,and MgO in the study area were inverted,and the remotely sensed anomaly zones were finally summarized.Combining various types of previous data and geological features,we carried out geological information comprehensive collection,geophysical verification,and excavation verification work in remote sensing anomalies,and delineated two Pb-Zn mineralization bodies and one copper mineralization body,Pb-Zn mineralization has been verified and a comprehensive comparative analysis considers these three mineralized bodies to be ore bodies extending eastwards from the Weibao Pb-Zn deposit.
