The mineralogical and geochemical characteristics of silver bearing minerals and silver minerals of the Erentaolegai Silver Deposit in Inner Mongolia

对内蒙古额仁陶勒盖银矿床主要载银矿物和银矿物的矿物学地球化学特征研究表明：矿床形成与岩浆活动关系密切，成矿流体主要为岩浆热液，属典型的中低温岩浆热液矿床。银的赋存状态主要为独立银矿物，它们以包体、显微包体的形式存在于脉石矿物中。在锰银型矿石中，少量银以离子吸附状态存在。系统地划分了银矿物的８种成份系列，为矿山开采和选冶提供了依据。

Based on the study of mineralogical and geochemical characteristics of silver bearing minerals and silver minerals of the Erentaolegai Silver Deposit ,it is considered that the silver mineralization has close relation with magmatic activity . In other words, the mineralizing fluid is mainly magmatic hydrothermal solution , so the ore deposit belongs to typical magmatic hydrothermal deposit in low or medium temperature. The silver occurs mainly as an independent mineral existed in the form of inclusion or microinclusion in gangue minerals .A small amount of silver exist in a state of ionic adsorption in manganese silver type ores .The paper systematically divides silver mineral into eight composition series which offer a firm basis for ore mining and processing
