Abstract:

Quartz is widely distributed on the Earth’s surface. It has a broad range of industrial uses and other application prospects. Natural quartz, however, are not entirely SiO2 but contain other elements more or less, such as P, Ti, Ge, Al, B, Be, Ca, Na, K, H, and Li, affected by the physico-chemical conditions/properties of crystallizing melt or fluid as well as post-crystallization alterations (such as metamorphism, structural deformation, and thermal disturbance). Diagenetic study of quartz based on its trace element compositions plays a part in petrological and metallogenic investigations of mineral deposits. The impurity elements in quartz are in forms of lattice impurities or nano- to macro-scale inclusions, and the impurity type, quantity, and form (specially inclusions) affects the quality and industrial use of quartz directly. Here, topics including the luminescent properties and technical performance of quartz, quality classification and rating standard for high purity quartz, source materials of high purity quartz are systematically reviewed. Also, the distribution of fluid inclusions and types of mineral inclusions in quartz from the Zhangjinzhuang quartz sand (Northern Jiangsu) and Guposhan granite (Guangxi) were determined in this study by optical microscopy observations and laser Raman analysis to provide a basis for subsequent research. High purity quartz of high quality and value is naturally formed (such as crystal) or processed from high quality quartz raw materials. It is an environment-friendly strategic resource used in high-tech industries, such as semiconductor, high-temperature lamp tubing, fiber optics, precision optics, microelectronics, and solar energy. Researches on the evaluation system, ideal source rock and formation mechanism for high purity quartz raw materials are beneficial for ensuring a sustainable supply of high purity quartz raw materials and increasing the added value of quartz products.

Key words: quartz, high purity quartz, high purity quartz raw materials, quartz sand in Zhuangjinzhuang in Northern Jiangsu, Guposhan granite in Guangxi
