Abstract:

Quartz is the most developed gangue mineral in the gold ore deposit,passing through entire mineralization process as one of the main minerals which contained gold.Besides the residual protogenic quartz,massive deuterogenous quartz was formed in the mineralization process.Therefore,it is extremely essential to research the typomorphic peculiarities of quartz in the gold ore prospecting appraisal.This paper systematically dealt with the morphological peculiarities,impurity elements,lattice parameter,thermoluminescence,and infrared spectrum of quartz samples from the gold deposit.The results show that fine gold-bearing quartz accreted with granule dissemination pyrite and sericite closely,which took on granule xenomorphic crystal,smoky gray and obviously breaking phenomenon,contained higher levels of impurity elements such as K、Na、Au、Cu、Pb、Zn along with higher a0 and lower c0/a0,the thermoluminescence curves of quartz were complex and diversed with high peak and large integrated intensity,infrared spectrum took on high absorption peak near 3 400 cm-1 and 2 350 cm-1,with DH2O>1，and the highest DCO2.These features can be used to find gold prospecting in quartz vein zones.
