山东典型萤石矿的宝石矿物学特征研究
Study on Gemmological Mineralogical Characteristics of Typical Fluorite Deposits in Shandong Province
摘要
Abstract
As an important strategic mineral resource in China,the fluorite is widely used in industry,met-allurgy,glass and ceramics.The fluorite is favored by mineral collectors because of its colorful color,re-markable fluorescence characteristics and good crystallization habit.Currently,gemological and mineralog-ical characteristics of typical fluorite deposits in Penglai Jushangou in Yantai city,Tancheng Fangzhuang in Linyi city and Pingdu Sanhe Mountain in Qingdao city in Shandong province have not been systematically studied.Through hand sample observation,conventional gemological experiments,laser micro—Raman spectroscopy,electron probe microanalysis,as well as in—situ LA—ICP—MS trace element analysis,bas-ic properties,textures,spectral characteristics,ore—forming fluid source and formation environments of typical fluorite in Shandong province have been characterized in detail.It is showed that two dominant types of Raman spectra of fluorite can be identified:Type Ⅰ,with the peak value at 322 cm-1,while as for Type Ⅱ,except for the typical peak of 322 cm-1,there present 5 groups of spectral bands in the range of 800～3000cm-1.It is related to the peak of rare earth elements.The trace element geochemistry reveals that rare earth elements patterns of fluorite in Pingdu Sanhe Mountain in Qingdao city is flat type,with typical negative Eu anomaly and high crystallization under reducing environment.The ore—forming fluids are mainly derived from atmospheric precipitation.While the fluorite in Tancheng Fangzhuang in Linyi city and Penglai Jushangou in Yantai city show positive Eu anomaly,with low crystallization temperature and oxidation environment.The former ore—forming fluids are mixed fluids of seawater and atmospheric pre-cipitation,while the latter is mainly derived from seawater.关键词
