Characteristics of Lithium Beryllium Ore and Occurrence and Distribution of Rubidium Element in Ore, in Daqianggou, Jiulong, West Sichuan

Abstract

Daqianggou lithium beryllium deposit is located in Xinshangou - Daqianggou area, Naiqu village, Jiulong County, Ganzi Prefecture, Sichuan Province. The ore bodies occur in quartz diorite joints and biotite quartz schist joints of Triassic Xinduqiao Group. The main minerals in the ore are alkaline feldspar, albite and quartz, with contents of 31.35%, 23.75% and 30.33%, respectively; secondary minerals are muscovite and spodumene, with contents of 8.44% and 5.17%, respectively; also contains a small amount of clay minerals, apatite and other minerals. The contents of Li2O, BeO and associated Rb2O in the ore are 0.44%, 0.082% and 0.20%, respectively. In this paper, the optical thin section identification, chemical analysis, electron probe analysis and AMICS mineral automatic analysis were used, study on ore characteristics of Daqianggou lithium beryllium ore, find out the occurrence state and distribution law of rare metal rubidium element in ore. The purpose is to provide basic reference data for future exploration, development and comprehensive utilization of mineral resources.
