Peripheral Metallogenic Prediction Of The Inner Mongolia Bayern Dam-Villasto Ore Concentration Area

The Bairendaba-Vilasituo ore concentration area is located on the western slope of the southern section of the Great Xing'an Mountain,and belongs to the eastern section of the Central Asian orogenic belt in the geotectonic position,namely to the south of the Hegenshan fault,to the north of the Xilamulun fault,and to the west of the Nenjiang fault.The Paleozoic experienced the evolution process of the Paleo-Asian tectonic domain in the Paleozoic,and the Mesozoic was superimposed by the Mongolia-Okhotsk tectonic system and the Paleo-Pacific tectonic domain,resulting in multi-phase tectonic magmatism events in the area,accompanied by multiple phases.Metallogenic events.There are two main types of deposits in the mine,including the Bayernda Dam-Villasto structural magmatic hydrothermal silver-lead-zinc polymetallic deposit and the Vilasto porphyry-hydrothermal tin polymetallic deposit.According to the previous studies on the genesis of the deposits in the area,the ore-forming hydrothermal fluids and ore-forming materials of the two deposits have the same source and mainly have the characteristics of mantle source.Therefore,the two types of deposits have similarities in the genesis of the deposits,but there is a big difference in the metallogenic model.Both deposit models have important reference and guiding value for mineral prediction in the region.According to the analysis of geochemical data,the elemental anomalies in this area often appear in pieces,and many abnormalities are high in intensity and have good mineralization directivity.Ag,Pb,Zn,and Cu elements are the main ore-forming elements in the area,and the high-value areas of these elements often overlap.Based on the comprehensive study of geological information such as regional structure,magmatic rock,mineralization alteration and geochemical exploration and other geological anomaly information,this paper establishes a suitable comprehensive prospecting model and conducts ore prediction research on the periphery of the deposit.Following the principle of using geo-information as the guide and geochemical information as the forerunner,the comprehensive landmarks of geology,material,chemical and remote are used to determine the boundary oftheprospective area,and the prospecting area is predicted in the area.In this study,a total of four mineralization prospects were delineated in the region,namely: Yamato Equus-Villasituo's metal class I prediction prospects,Baiyin Ula lead-zinc-silver polymetallic class I prediction prospects,large It is a Bayan Gule lead-zinc polymetallic II metallogenic prospecting area,Wusu Yinsala hot copper lead-zinc-silver polymetallic III metallogenic prospecting area.The division of the prospects indicates the direction for the next prospecting work in the area.
