长安金矿是近年来在哀牢山金矿带发现的另一种独特类型的金矿床。通过对前人研究成果和新获得的深边部勘查资料的综合研究，认为长安金矿主矿体呈似层状、透镜状，向 NE 陡倾产于 NNW向的 F6断层破碎带东亚带砂泥质构造岩中，矿体走向及倾向上具有膨大缩小、舒缓波状变化特征；F6断裂为最主要的控矿构造；断层破碎带东亚带中砂泥质碎裂岩、角砾岩金矿化较强，西亚带白云质构造岩金矿化微弱；喜山期辉绿岩、煌斑岩、正长斑岩、细晶正长岩等岩浆侵入活动与金成矿关系较为密切，提供了重要成矿流体。砂泥质碎裂岩、角砾岩和侵入岩脉与围岩接触带、断裂交汇处对金成矿有利，受硅化、黄铁矿化、毒砂化等多种蚀变叠加的部位，易形成工业金矿体。

The Chang’an gold deposit is another peculiar deposit discovered in Ailaoshan gold metallogenic zone in recent years.Based on a comprehensive study on precedent achievements and the new data collected in depth and edge exploration,the following conclusions are made:the main gold orebodies are in stratoid and lenticular structure and steeply dip to NE,and they occur in the arenaceous politic tectonic rocks of east subzone of NNW-trending F6 shattered fault zone.The alignment and inclination of the orebodies are charac-terized by expansion,contraction and smoothly wave-like variation.F6 fault is the most primary ore-control-ling structure.Gold mineralization of arenaceous politic cataclasite and breccia is intensive in east subzone of shattered fault zone,while gold mineralization of dolomitic tectonic rocks in west subzone is weak.The mag-ma intrusion activities of Himalayan dolerite,lamprophyre,orthophyre and aplite syenite are closely related to gold mineralization,and they provide important ore-forming fluids.Arenaceous politic cataclasite,brecci-a,and contact zone of intrusive rock vein and wall rocks,and fracture intersection are favorable for minerali-zation of gold.In the locations under alteration and superimposition such as silicification,pyritization and ar-senopyritization industrial gold orebodies are easily formed.
