Timing of granite pegmatite-type high-purity quartz deposit in the Eastern Qinling,China:constraints from in-situ LA-ICP-MS trace analyses of quartz and monazite U-Pb dating
文献摘要：
Eastern Qinling,China is one of the important rare metal metallogenic provinces with extensively dis-tributed granite pegmatite dikes.The No.5 granite peg-matite intruded into the granitic gneiss of the Qinling Group,and the major minerals are quartz(39.8％),K-feldspar(18.8％),albite(36.3％),muscovite(3.4％),and garnet(1.1％).Monazite U-Pb isotopic dating indicates that the No.5 pegmatite from the Eastern Qinling was emplaced at ca.420.2±2.2 Ma,which confirms that high-purity quartz mineralization probably formed during the Early Devonian.In-situ laser ablation inductively coupled plasma mass spectrometry analysis of quartz show that quartz samples from Eastern Qinling have total trace ele-ment concentrations(Al,Ti,Sc,Li,B,Cr,Mn,and Fe)ranging from 23.2 to 52.8 ppm,slightly higher than the quartz(impurity element content from 13.4 to 25.9 ppm)of the Spruce Pine high-purity quartz deposit in western North Carolina.The No.5 pegmatite of Eastern Qinling could be defined as one high-purity quartz deposit of China.
