【摘要】 对额仁陶勒盖银矿床中石英的稀土元素、包裹体测温、包裹体成分、同位素、化学成分及红外光谱学特征等进行了研究 ,认为额仁陶勒盖银矿床属于浅成中温热液成因 ,早期成矿流体为岩浆热液 ,晚期成矿流体天水居主导地位 ,矿床形成于弱酸性—弱碱性条件下及还原环境中。石英的红外光谱学特征、石英的化学成分及形态是该银矿床重要的找矿矿物学标志。更多还原

【Abstract】 Mineralogical characteristics of quartz in the E’rentaolegai silver deposit, such as REE, fluid inclusion, oxygen and hydrogen isotopic composition, chemical composition, and infrared absorption parameters are described in this paper. And it is considered that the silver deposit is an epithermal deposit, and the metallogenic fluid in the early stage was mainly magmatic solution, the metallogenic fluid in the late stage was mainly meteoric water. The silver deposit was formed under reducing, weakly acidic and basic conditions. The IR spectral characteristics, chemical composition and typomorphic characteristics of quartz are the important prospecting criteria for this deposit.更多还原
