摘　　要：吉林省集安市米架子金矿,是近几年发现的中型金矿床,位于吉林省集安市境内,鸭绿江多金属成矿带的中部。矿床赋存于燕山期龙头岩体与集安群地层的内外接触带中,严格受北东向和北东东向构造控制。目前区内已发现21条金银及多金属矿体,均产自接触带内中-基性及酸性脉岩的上下盘,经野外实际工作和室内综合研究,基本确定了金银及多金属矿床的赋存规律。The micai gold deposit in Ji'an City,Jilin Province,is a medium-sized gold deposit discovered in recent years.It is located in Ji'an City,Jilin Province,in the middle of Yalujiang polymetallic metallogenic belt.The deposit is located in the inner and outer contact zone between the leading rock body and the stratum of Ji'an group in Yanshan period,which is strictly controlled by the NE and NE structures.At present,21 gold,silver and polymetallic ore bodies have been found in the area,all of which are from the upper and lower walls of intermediate basic and acid dykes in the contact zone.Based on field work and indoor comprehensive research,the occurrence rules of gold,silver and polymetallic deposits have been basically determined.
