Research on Geochemical Characteristics of Granite Pegmatite Containing High-purity Quartz,in the Southern Lushi County,West of Henan Province
摘要
Abstract
The Guanpo-Shiziping-Wayaogou area of the southern Lushi county,also the largest concentration area of granite-pegmatite dikes in Henan province,keeps complex and diverse types of pegmatite.In this paper,13 representative samples of the study area were observed in the field and under the microscope.Combined with the verification of High Purity Quartz Purification Technology,it was be found that some special types of granite pegmatite,such as muscovite-albite and muscovite-monzonite granite pegmatite,can be purified into quartz sand with SiO2 content exceeding 99.99%.This result suggests that the high-purity quartz mineral distribution is not uniform in space,and it has specific lithology requirements for pegmatite.According to the results of lithogeochemical analysis,the element of the granite-pegmatite containing high-purity quartz in the southern Lushi County of Eastern Qinling mountains is equivalent to alkali granite or K-rich granite,which suggests that the pegmatite was formed in the tensional tectonic setting.In addition,the trace element composition of pegmatite is close to the LCT pegmatite so that the parent rock was presumed to be Huichizi monzogranite,which was emplaced to the Zhaigen formation.The granite pegmatite containing high-purity quartz is similar to LCT-I type pegmatite.关键词
