摘要
大兴安岭地区是我国北方重要的银成矿区 ,在所发现的十多个银矿床中 ,银主要呈独立银矿物形式产出。大兴安岭地区银矿床中已发现近 40种独立银矿物和几种尚未定名的银矿物 ,这些银矿物在大兴安岭地区不同成因类型、不同物质组分、不同温压条件的银矿床中均表现为低温后期成矿的特点 ,温度是控制银矿物沉淀的主要机制。
More than 10 silver deposits were found in the Dahinggan Ling Mountains, where there is an important silver mineralization belt in the north of China. Silver occurs mainly as independent silver minerals, and less than 40 silver minerals have been discovered and they make up 15 chemical composition series. The minerals bearing silver minerals, silver minerals occurring in the deposits, which are different in ore forming time, chemical composition and genesis, were formed under low temperature conditions in the Dahinggan Ling Mountains. Furthermore, the temperature is the most important factor that controls the deposition of silver minerals.
