| Abstract: | Quartz is well spread in the deposit and can be divided into five minerogenetic periods. The color, grain size and crystal morphology of quartz can indicate the degree of mineralization. Quartz formed in different minerogenetic periods contains different chemical elements. The contents of Al, Cr, Li, Pb, As, Ca and Mg in quartz are positively related to mineralization. The cell parameters of quartz measured by X ray powder diffraction are controlled by chemical compositions, which have positive relationship with the content of Al in quartz. The crystallinities of quartz formed in the main mineralizing period are lower than those of quartz formed in nonmineralizing periods. The ratio of D 1/D 0 in higher than 6.00 and has CO 2 absorbing peaks in infrared spectroscopic diagrams of quartz, which can indicate mineralization. The electron paramagnetic resonance studies of quartz show that the higher the concentration of the O -(Al) center, the better the mineralization. The specific gravity of quartz decreases with the evolution of hydrothermal fluid. |
