Abstract:
Through studing the strata,the characteristics of ore and wallrock alteration in Daxintun gold and polymetallic deposit,analyzing the ore-controlling conditions of this area,we think that the strata,structure and igneous rocks are related to gold mineralization.Beikuanhe group provide material sources for mineralization,and promote the occurrence of mineralization.Ore -controlling structure is significantly,the gold,silver and antimony orebody,which have been found in the region,produce in NW trending fracture zones,orebody are mainly distributed in the contact zone of the intrusive rocks.Epithermal vein rock provides sufficient mineral and thermal conditions for the formation of gold and polymetallic deposits.The district delineat 21 orebodies,including 17 gold bodies,3 antimony bodies and one silver body,they are quartz vein type ore.In order to promote in-depth exploration work in the further,we establish prospecting criteria,and point out that we should focus on the inside and outside contact zone of vein rocks,the development sites of carbonate and the richment parts of the geochemical indicator elements(As,Sb)to find quartz vein and altered rock type gold and polymetallic deposits.
Key words: Gold and polymetallic ore, Ore-controlling condition, Prospecting criteria, Daxintun gold deposit, Heilongjiang Province
