摘要
大黑山金矿区是赋存于大庙花岗岩体外接触带的破碎蚀变岩型和石英脉型金矿 .通过对本区矿石中金矿物的粒度、形态、赋存状态和成分等标型特征的研究 ,探讨了金矿床的选矿方法、金矿物世代、矿床形成深度等几个方面 .认为本区金矿物的粒度和成色反映了浅 -中成中温热液矿床的特点 ,其成因类型属浅
In the exocontact zone of Damiao granite,Daheishan gold deposit belongs to the tectonically fractured metasomatite type and quartz vein type.According to the study on the typomorphic characteristics of gold mineral grain sizes , morphology, occurances and components in this deposit,the benefication,ways,the generation of gold minerals and and formation depth of deposit are discussed. It is considered that the grain sizes of gold minerals and the fineness of native gold reflect the main features of middle or shallowed seated and mesothermal hydrothermal solution in this deposit,the gold mineralized type belong to middle or shallowed seated and mesothermal hydrothermal solution.
