THE FIRST-ORDER MATALLOGENIC UNITS IN HEILONGJIANG PROVENCE: New Division of Metallogenic Domain

In view of the demand of geological and mineral resources work and research for the geodynamic background of minerals of various ages in Heilongjiang Province, based on the research progress of basic geology in Heilongjiang in the past 30 years, according to the latest tectonic division plan of the province, the first-order metallogenic units(metallogenic domain)are redivided as follows: Paleo-Asian Ocean metallogenic domain(Pt₃-P₁), Paleo-Asian Ocean and Paleo-Pacific Ocean superimposed metallogenic domain(D₁-P₃), Mongolia-Okhotsk Ocean metallogenic domain(P₂-early K₁), Paleo-Pacific metallogenic domain(D₁-K₁), and marginal-Pacific metallogenic domain(K₂-Q). The discussion on the influence time limit and scope of each first-order metallogenic unit(metallogenic domain)provides new thought for the ore prospecting in Northeast China.
