摘要：

东安金矿床是与中生代火山—潜火山岩有关的浅成低温热液型金矿床。矿床中发育一套典型的低温热液急蚀变矿物组合, 包括银金矿、自然银、辉银矿、黄铁矿、毒砂、黄铜矿等, 蚀变作用主要为次生石英岩化、冰长石化、硅化、绢云母化、绿泥石化、泥化、玉髓化、萤石化等。矿物包裹体表明: 主成矿过程发生在300~200 m之间, 成矿初始深度为0.2~1.0 km。

Abstract:

The Dongan gold deposit is an epithermal type gold deposit related to volcano-meta volcanic rock. There develops a typical epithermal mineral association in the deposit, which consists of electrum, native silver, argen tite,pyrite,arsenopyrite, chalcopyrite, etc. The alterations are mainly secondary quartzitization, adulariazation,silicification, sericitization, chloritization, pelitization,chalcedonization, fluoritization, etc. mineral inclusion studies show that the main ore-forming process occurred in the temperture range of 300~200 m. The primary ore-forming depth is 0.2-1.0 km.

Key words: alterative mineral character, epithermal type gold deposit, Donan
