LTD, Bayan Nur 015000, Inner Mongolia, China; 2. Lanye Supervision Co. LTD, Lanzhou 730000, Gansu, China） Abstract: Through the analysis of copper orebody characteristics, geochemistry and other controlling factors of the huogeqi copper mine, it was realized that mine copper orebody mainly occurs in the banded quartzite in the middle of second group of Langshan mountain formation, where the structures control the deposit distribution, the stratum controls the size of orebody, the lithology controls the type and occurrence of the ore bodies. Therefore, it was a typical SEDEX deposits for sedimentary rock as the host rock, and it was transformed by metamorphism or magmatism. The purpose of this paper was to further understand the metallogenic regularity of the huogeqi copper mine for deep and peripheral exploration.
