Geological Characteristics And Prospecting Direction Of The Hu He Tao Le Gai Pb-Zn Deposit Inner Mongolia

The study area is located in the southern part of Inner Mongolia,The tectonic location is located in the fold belt of the northern edge of North China Plate.It belongs to the northern margin of the inner Mongolian axis and the southern margin of the late Hualixi fold belt in Inner Mongolia.The joint part of the Yinshan east-west structural belt and the Daxinganling uplift fold belt.This paper is based on the Huhetaolegai Pb-Zn Deposit,in Zhengxiangbaiqi,Inner Mongolia,and guided by modern geoscience and metallogenic theories.Through field geological investigation,geophysical and geochemical methods,Based on indoor testing and comprehensive analysis,Systematic study on geological characteristics,ore body characteristics and prospecting indicators of Pb-Zn polymetallic deposits in the study area,Research suggests that low to moderate temperature hydrothermal fluids rich in ore-forming elements migrate in structural fracture zones,And react with the fracture zone and surrounding rock,Ultimately integrated mine.The location of the lithology is not obvious.The ore body is assigned to the structural fracture zone,and the genetic type of the deposit is epithermal low-temperature hydrothermal Pb-Zn deposit.The geological prospecting criteria in the study area is a tectonic fracture alteration zone,and the wall rock alteration marks are silicification,limonitization,and iron-manganese mineralization.The geophysical prospecting indicator is a high-polarization medium-high-impedance anomaly,and the anomalous gradient of the anomaly is obvious.The area with apparent polarization greater than 2% and apparent resistivity greater than 700?.m is a favorable prospect for prospecting.The geochemical indicators are characterized by large anomalies,well-arranged abnormal elements,obvious concentration centers,and high anomalous intensities,and the main combined elements are Pb,Zn,Ag,As,Sb,Bi,etc.Initially,four mineralized alteration zones were identified,and the mineralization elements were Pb and Zn.12 orebodies have been delineated,of which the main ore body is 100 m long,the pseudo-thickness is 2.76 m,the Zn is 3.29%,and the Pb is 1.18%.Through the study of geological characteristics and prospecting indicators of Pb-Zn polymetallic deposits in the study area,significant progress has been made in the prospecting breakthrough in the study area,which also has important guiding significance for further prospecting in the study area and region.
