Beryl occurrences in the granitic complex of Guerioune, Laouni, Southeastern Algeria: electron microprobe, infrared spectroscopy, and fluid inclusions data
The Guerioune beryl is green or light green; the color is mainly due to the presence of Cr substituting Al in the beryl structure. The Cr2O3 and V2O3...
