水晶资源的特征、工业应用、矿床类型及找矿前景分析OA

[Objective]Rock crystal is an important non-metallic mineral resources.As one of the gemstones,it can be used as a raw material for high-purity quartz.Rock crystal mine in China has a poor resource endowment,with piezoelectric crystal reserves of 18687 kg,smelting crystal reserves of 418.70 t,and process crystal reserves of 52 kg,and low reserves.[Methods]By collecting published literatures,this paper summarizes the distribution,genesis types,and industrial application of rock crystal resources.[Results]Rock crystal deposits can be divided into two kinds:endogenic and exogenic,of which endogenic deposits can be divided into pegmatite type,hydrothermal type,skarn type,and exogenic deposits are mainly placer type,which can be divided into residue-slope type and slope-alluvial type.Hydrothermal rock crystal deposits are the main industrial type.The world's rock crystal deposits are mainly distributed in Brazil,which accounts for 90％of the world's resource reserves.China's rock crystal deposits are primarily distributed in Guangxi,Sichuan,Yunnan,Heilongjiang,Jiangsu,and other places.[Conclusions]Based on previous research information,although synthetic rock crystal technology has been quite mature,natural rock crystal still has an important development and utilization of significance.Many regions in China have large potential for finding minerals.For example,many authigenic deposits are found in Guangxi,Guangdong,Heilongjiang,etc.,as well as the eastern coastal areas of the Dabie-Sulu ultrahigh-pressure metamorphic belt.
