The Metallogenic Characteristics And Prospecting Direction Of Duobaoshan Cu-Au Metallogenic Belt,Heilongjiang Province

Duobaoshan metallogenic belt was located in the east of the Central Asia-Mongolia porphyry copper mineralized belt, and the border of Mongolia-Daxinganling fold and the northeast part of Jilin-Heilongjiang fold. the superlargeDuobaoshan porphyry Co-Mo deposit,the large scale Tongshan porphyry Co-Modeposit, and the large scale Zhengguang epithermal rock gold deposit have beenfound in this area. Previous geologists have made systematic study of the typicalCo-Au deposit of Duobaoshan area, and have achieved a large amount of studyresult.but they were still lack of unified understanding upon metallogenic controlcondition,deposit genesis and metallogenic regularity of the entire Duobaoshan area.This article starts from the comprehensive study and analysis of the three typicaldeposits on the Duobaoshan metallogenic belt:Duobaoshan copper deposit,Tongshancopper deposit and Zhengguang rock gold deposit,and analysed the resoursespotential and the exploration prospect of Duobaoshan metallogenic belt.Duobaoshan deposit is the key deposit on Duobaoshan metallogenic belt,and is aporphyry copper deposit. Mid Hercynian granodiorite porphyry is closely related tothe mineralizaion.Tongshan deposit is also one of the key deposits of Duobaoshan metallogenicbelt. Duobaoshan Group is the closest to the mineralization.Zhengguang gold deposit is a tectonoalterative epithermal deposit,the magmaticthat is closely related to the mineralization is the Early Jurassic diorite. By the study on the typical deposits, summarized the regularity of exploration onDuobaoshan metallogenic belt, and also pointed out that in the surrounding areawhere porphyry copper deposit have been found, more attention should be paid on theexploration for the hydrothermal gold deposit.
