Gold metallogenic rule and prospecting forecast in the west of Tieling-Co-Jingyu mineralization belt

The tectonic-magmatic activity of the west of Tieling-Co-Jingyu mineralization belt had the features of multicycle. The granite-greenstone belt is the major source bed of the deposit. The analysis of the metallogenic feature of the classic gold deposit show that there are 2 times gold mineralization and forms 2 types gold deposit, that is the altered stratabound gold deposit controlled by the ductile shear zone of Later Archeozoic to Early Proterozoic and the magmatic hydrothermal deposit controlled by the middle-acid magmatic rock of Later Yanshanian. The major ore control place is the join point of the regional deep fault, especially where the NW strike fault developed and superpose the middle-acid intrusive rock of Later Yanshanian forms gold concentration area. On the base of the above study the prospecting forecast had been carried through.
