Abstract:

Baoxinggou gold deposit is in Tahe County,Heilongjiang Province,located on the north of Daxing’anling and south margin of upper Heilongjiang Foreland Basin,It is another rock-gold deposit with greater potentiality， after Shabaoshi rock-gold deposit,which located on the north margin of the basin.The probable geochemical anomaly combination is Au,Ag,As,Sb,Cu and Pb.The characteristics of element combination reveals that the mineralization in the area has underwent multi-epoch and multi-phase hydrothermal activities, being favorable to the ore-formation.The ore-controlling factors for this deposit:ore-forming material derived mainly from Ershierzhan Formation of Middle Jurassic,NE-trending structures fracture belt is pathway for migration of the mineralizing fluid and favorable position for ore-bearing,porphyry bodies provided enough ore-forming fluid,thermal source and partly  metallogenic material.
