Studies have shown that the luminescence properties of quartz, may be a good criterion for identifying and assessing the pegmatite mineralization. X-ray luminescence spectra revealed that dramatically increases the concentration AlO44- / Li + centers in quartz of rare metal pegmatites. The curves of the quartz thermoluminescence maxima are clearly seen in 220-240S temperature ranges that may also be associated with a bellows, which serve as alkali metal ions, such as Li.
