摘      要：Si,Al,Ca,Mg,Fe,Na,K,CO;,F,*** detected from the fluid inclusion *** these constituents,Si,Na,and CO;are predominant,amounting to more than *** indicates that the ore-forming solution must be alkalino with Si,Na,and CO;as its dominant *** temperatures for the solution range from 80 to360℃.Although rock quartz can crystallize at the above temperature interval,perfect crystalsof economic importance are largely formed below 260℃.The temperature of formation in-creases toward the granite intrusives at a rate of about one degree per *** is esti-mated from the lithostatic load that the salinity of rock quartz is 17—23（NaCl wt%）,while that of vein quartz is relatively high as compared with the *** is a ten-dency for the salinity of the ore-forming solution to increase with depth.
