Use of Spectrographic Analyses to Characterize the Unique Features of Sodic-Lithian and Cesium-Rich Platy Beryl

Since most beryls are characterized by prismatic configuration and originate from pegmatite and granite,platy beryl is considered especially rare. Therefore,the aims of this study are to determine the spectrographic and chemical characteristics of the platy beryl;examine the relationships between the spectrographic parameters and alkali elements and discuss the possible genesis of its platy habit based
