THE SOURCE OF GOLD ORE-FORMING MATTER AND PROSPECTING GUIDE IN THE UPPER HEILONGJIANG BASIN

Gold deposits and occurrences are broadly distributed in the Upper Heilongjiang Basin. Based on the study on the geology, distribution, microelements and stable isotopes of the gold deposits, it is concluded that the sandstone of Xinghuadukou and Ershierzhan groups supplied the ore-forming matters. The metallogenic and prospecting model of source bed-structure-magmatic rock is proposed, by which the potential metallogenic areas are predicted.
