石英在金矿床中的重要性是众所周知的,对石英含金性的评价乃是当前各产金国家的重点科研课题。随着找矿难度的提高,解决这方面的问题更显得迫切。由于矿床学成矿理论的不断发展,热液型金矿床已可详细地划分为岩浆热液、变质热液、混合岩化热液和渗流热卤水热液型金矿床等,而区分这些不同类型热液金矿床的矿物学标志尚有待研究。作者对我国陕西某“卡林型”金矿床(沉积岩中浸染型金矿床)中的石英进行了初步的矿物学研究,可为石英含金性评价问题和热液金矿床类型详细划分的鉴别标志问题提供一些基础资料。
The importance of quartz in gold deposits is well known. The evaluation of the gold content of quartz is the key scientific research issue of the current gold producing countries. With the difficulty of prospecting to improve, to solve this problem is even more urgent. Due to the continuous development of mineralization and ore prospecting, hydrothermal gold deposits can be divided into magmatic hydrothermal fluids, metamorphic hydrothermal fluids, mixed petrified hydrothermal fluids and percolation hydrothermal hydrothermal gold deposits, etc., to distinguish these different types Mineralogical signs of hydrothermal gold deposits have yet to be studied. The authors carried out preliminary mineralogical studies of quartz in a “Carlin” gold deposit (disseminated gold deposit in sedimentary rocks) in Shaanxi Province of China, and can be used as a distinguishing mark for the detailed evaluation of quartz gold evaluation and classification of hydrothermal gold deposits Questions provide some basic information.
