Geological characteristics,metallogenic regularities,and prospecting indicators of Maotoushan Gold Deposit in Aohan Banner,Inner Mongolia
Maotoushan Gold Deposit is located in the eastern part of Chifeng City,Inner Mongolia Autonomous Region.It is widely distributed in the gold deposits of the northern margin of the North China Craton.This paper sys-tematically expounds the geological characteristics of Maotoushan Gold Deposit,suggesting that the ore bodies are located in the Lower Permian Jiujuzi Formation,and the mineralized rocks consist of metamorphic sandstone,red chert,and carbonaceous slate.Gold is present in the form of hydrothermal superimposed quartz veins and veinlets,which are con-sistent with the attitude of the strata,indicating a sedimentary-dynamic metamorphic gold deposit.The metallogenic regularities and ore-controlling factors of Maotoushan Gold Deposit are summarized,and prospecting indicators are pro-posed,providing theoretical references for the exploration and prospecting of similar gold deposits along the northern margin of the North China Craton.
