摘　　要：甘肃省铜砷矿床绝大部分位于甘南州年木耳至合作一带,本区呈北西~南东向带状,长度130km,宽20km~30km,共发现和评价矿产地8处(中型矿床4处、小型4处),产地密集,类型齐全,计有斑岩型、矽卡岩型和热液型,铜砷矿床与铁、铅、锌、金、银、硫等金属和非金属矿伴生和共生,是很有远景的地区。文章重点论述分了甘南州年木耳至合作一带铜砷矿床的成矿地质条件。Most of the copper arsenic deposits in Gansu Province are located in the nianmu'er-hezuo area of Gannan Prefecture.The area is in a NW-SE belt,130km long and 20km~30km wide.A total of 8 Mineral sites(4 medium-sized deposits and 4 small ones)have been found and evaluated.The origin is dense and the types are complete,including porphyry type,skarn type and hydrothermal type.Copper arsenic deposits are related to iron,lead,zinc,gold,silver Sulfur and other metal and non-metal ores are associated and symbiotic,which is a promising area.This paper focuses on the metallogenic geological conditions of copper and arsenic deposits in nianmu'er-hezuo area,Gannan Prefecture.
