TYPOMORPHIC CHARACTERISTICS OF QUARTZ FROM LIUHE GOLD DEPOSIT IN JILIN PROVINCE: Application in Ore Prediction

The gold content of quartz from Liuhe gold deposit in Jilin Province is quantitatively analyzed with the typomorphic characteristics of quartz. The result shows that the cell parameters of quartz from the Au-free vein are apparently smaller than those from the Au-bearing vein. The trace elements in the quartz from Au-bearing vein are characterized by certain Al-alkaline content, much Fe, less Ba, and lower average contents of Co, Cr, Rb, Cs, Sc and Ta than the background value of the orefield. The H₂O and CO₂ contents in the inclusion of Au-bearing quartz are evidently higher than those of Au-free quartz. Based on such analysis, with study on the structure-controlling law and geochemistry of the deposit, a prediction for the mineralization in the deep of the orefield is carried out.
