Quartz grains are individualized according to the textural crystallographic analysis. On the other hand, with the help of CL, it was possible to describe many domains of defect concentration in quartz. Carbonates and phosphates exhibit a characteristic luminescence mainly due to the presence of activator elements.
Grain-size analyses were performed by Laser Diffraction. Also, a morphoscopy analysis of selected quartz grains was conducted with a binocular magnifying glass, while the surface textures of...
