摘要
The occurrence of the beryllium mineral in the beryllium deposit in the Xinjiang Province is identified and tested by combination of electron probe micro-analyzer and micro X-ray diffractometer. Firstly, the identification markers of the beryllium mineral on the observation of back-scatted image is determined and the quality analysis of energy dispersive spectrometry are as follows: 1) the brightness of the beryllium mineral in back-scatted image is lower than that of quartz; 2) only the peaks of silicium and oxygen are displayed in the X-ray spectrum; and 3) tpeak height of oxygen is higher than that of silicium. The Kα peak of Be element emerges at 177.384 mm analyzed by LDE3H analyzing crystal. The semi-quantitative results show that the contents of Si and O elements are 21.93% and 60.06%, respectively, similar to the theoretical value [w(Si): 23.53%, w(O):60.50%] of bertrandite.
