| The study area is located in Horqin Right Middle Banner,Tuquan county of,eastern Inner Mongolia,and the tectonic position is in the eastern part of the sorenxilamuron Paleozoic junction zone of the Siberian plate and the north China plate.This paper uses 1:50,000 ore original geological data to generalize the formation and the intrusive rock,established the sequence stratigraphic framework and the intrusive rock in the study area,In this paper,three typical deposits of copper polymetallic ore are analyzed,namely,the Naoniushan copper deposit in Tuquan county,Lianhuashan copper and silver deposit in Tuquan county,Budunhua copper deposit in Horqin Right Middle Banner.The structural characteristics,and the relationship between geophysical and geochemical anomalies and mineralization are studied,and the typical ore deposit model is establishedUsing geochemical data to delineate 14 geochemical comprehensive anomalies,among them,there are 9 anomalies with Cu as the main metallogenic element and 5 anomalies with PbZnAg as the main metallogenic elements.The map of aeromagnetic anomalies in the study area was recompiled with 1:50,000 original aeromagnetic data,and a total of 200 aeromagnetic anomalies were collated.The relationship among regional geophysical characteristics,geochemical anomalies and mineralization were analyzed.Based on geological,geophysical and geochemical anomalies,as well as information of mineralization and alteration,the most representative typical ore deposit metallogenic patterns and ore prospecting marks were combined to make ore prospecting predictions,and four ore prospecting scenic spots and a key prospecting target area of type A and type B are selected.The research of this paper provides a theoretical basis for ore prospecting in the area of Tuquan-Horqin Right Middle Banner,and has a certain reference and reference value for ore prospecting and prediction of similar deposits. |
