First Discovery of the Longquanping Pegmatitic High-purity Quartz Deposit in the Area of Lushi, Henan: Implications for Exploration
-
摘要:
河南卢氏龙泉坪伟晶岩型高纯石英矿床位于北秦岭构造带东部。矿床赋存于秦岭岩群石槽沟组和峡河岩群寨根组中，矿石类型为白云母花岗伟晶岩型，其主要矿物成分为钠长石(31%~51%)、微斜长石(11%~20%)、石英(25%~38%)和白云母(7%~9%)，含少量石榴子石(1%~2%)、黑云母(< 1%)等；石英矿物经深度提纯SiO2含量可达99.997%。与美国Spruce Pine伟晶岩型高纯石英矿床对比，两者具有相似的成矿地质背景和地球化学特征。通过系统的调查分析，本研究认为北秦岭和阿尔泰地区具有寻找伟晶岩型高纯石英矿床的潜力；不含稀有金属矿化、流体包裹体含量低的伟晶岩是寻找高纯石英矿床的理想目标地质体。龙泉坪伟晶岩型高纯石英矿床的发现对我国高纯石英资源地质勘查具有重要的示范和引领作用。
Abstract:The Longquanping deposit of Lushi, Henan Province, is located in the eastern part of the North Qinling Tectonic Belt. The deposit is hosted by both the Shicaogou Formation of the Qinling Group and the Zhaigen Formation of the Xiahe Group. The granite pegmatites which contain quartz ores are mainly composed of 11%-20% plagioclase, 25%-38% quartz and 7%-9% muscovite, with a small amount of garnet (1%-2%) and biotite (< 1%). The SiO2 content of quartz is up to 99.997% after deep purification. Compared with the Spruce Pine pegmatite-type high-purity quartz deposit in the United States, the two share similar metallogenic geological background and geochemical characteristics. The study suggests that the North Qinling and Altai areas have the potential to find pegmatite-type high-purity quartz deposits. It is noted that the pegmatites which are free of rare metal mineralisation, with low abundance of fluid inclusions, are ideal targets for the discovery of high-purity quartz deposits. The discovery of the Longquanping deposit has an important demonstration and leading role in the geological exploration of high-purity quartz deposits in China.
