The Gaosongshan gold deposit is a newly discovered low sulfur type epithermal deposit in northeastern Heilongjiang��located in the overlapping part of the Tianshan--Mongolia--Xing'an orogenic belt and the circum-- Pacific tectonic belt�� Combined with the comprehensive analysis of regional geological background��geological characteristics of deposits and petrological geochemical data��the authors considered the Gaosongshan gold deposit produced in the middle and basic volcanic rocks of island-arc or active continental margin environment�� The metallogenic model is the water-rock reaction between middle and basic calc-alkaline volcanic rocks and magmatic hydrothermal formed in late continental collision or after collision��during the process of extrusion translates into extension between the Pacific and Eurasian plates in Middle and Late Cretaceous��and finally enriched and formed deposits at the intersect parts of volcanic mechanism and regional faults��
