摘　　要：新安屯铜钼矿是吉林省近年来新探明的一处小型热液型铜钼矿床。矿石矿物主要为黄铜矿、辉钼矿、黄铁矿;脉石矿物主要为石英、长石。按照地质特征、矿石矿物共生组合、结构、构造、蚀变特征及相互关系,把成矿过程划分为三期、四个阶段。成矿阶段的划分充分揭示出矿床的形成过程,为矿床成因的探索提供了充实的地质依据。Xin’antun copper-molybdenum deposit is a small hydrothermal deposit newly discovered in Jilin Province recent years. Ore minerals are mainly chalcopyrite,molybdenite and pyrite;gangue minerals are mainly quartz and feldspar. According to the geological features,ore mineral symbiotic assemblage,structure,alteration characteristics and their interrelations,the metallogenic process is divided into three stages and four stages. The division of metallogenic stages fully reveals the formation process of the deposit and provides a substantial geological basis for the exploration of the genesis of the deposit.
