英文摘要High purity quartz is an important strategic resource. This paper systematically summarizes the petrographic characteristics, impurities' existing state and formation and evaluation methods for high purity quartz. The results suggested that: (1) Potential rocks that can be used as raw materials for high purity quartz include granite pegmatite, quartz vein, and crystal. The quartz that crystallized in late stage of magma evolution-early stage of the pegmatitic granite (NYF) may be more possible to form high-purity quartz; Moderate metamorphism and deformation in the later stage is beneficial for the formation of high purity quartz. The quartz mineral is transparent to semi-transparent, with minimal mineral structural fractures. The mineral composition of pegmatite type ores is usually composed of quartz, albite, perthite, muscovite, etc., minimal content of mafic minerals, without rare metal minerals and volatile minerals. (2) The main factors affecting quartz purity include: gangue minerals and grain boundary impurities, inclusions, lattice-bound elements, etc. The type, quantity and size of inclusions are the most critical indicators for inclusions evaluation. The quantity of mineral inclusions, gas-liquid inclusions, and < 10 mu m inclusions in quartz minerals should be as low as possible. Al and Ti are the most important elements for lattice-bound elements evaluation, and typically require Al < 50 x 10(-6) and Ti < 10 x 10(-6). (3) It is recommended to conduct evaluation and research work from macro to micro levels, and the order can be: Geological occurrence characteristics-the inclusion characteristics, configuration and content of lattice-bound elements in quartz. We can use optical microscopy, scanning electron microscopy (SEM), cathode fluorescence (SEM-CL), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), to conduct research work.
