摘　　要：栾灵金矿位于小秦岭成矿带东部,属于碲化物型金矿床。该区矿石矿物组分简单,金属矿物主要有自然金、碲化物和硫化物3种类型,其中,自然金形成于早期的多金属硫化物阶段,而金的碲化物形成于晚期的碲化物阶段。碲矿物主要有碲金矿、碲金银矿、针碲金银矿和碲银矿等。金的赋存状态有两类,即可见金和次显微金,根据物相分析结果,金矿物以包裹金为主,裂隙金和粒间金相对较少。通过分析该矿床成矿作用过程,认为其成因属于中低温碲化物热液型。Luanling gold mine is located in the east of Xiaoqinling metallogenic belt,it belongs to telluride-type gold deposit.The ore mineral composition is simple in this area,metallic minerals are mainly native gold,telluride and sulfide,the native gold form in the early stages of polymetallic sulfide,but the gold telluride form in the late stages of telluride.Telluride minerals are mainly tellurium gold ore,tellurium gold and silver ore,needle tellurium gold and silver ore,tellurium silver ore and so on.There are two types of gold occurrence,which are sub-microscopic gold and visible gold.According to the results of phase analysis,we think gold mineral is mainly gold package,crack gold and intergranular gold are relatively less.By analyzing the process of ore forming of the mine,we draw that the genesis is low temperature telluride hydrothermal gold deposit.
