Abstract:
Cuijia gold mine is located in the north-east segment of Lingbei-Shuangmuding fracture in Zhaoyuan-Laizhou gold belt,16 veins have been discovered in the area,among them,1,10 and 13 veins contain industrial orebody. Through analysis of the regional geological conditions,we think that the initial source bed,containing-ore heat body and structure are the main ore-controlling factors in gold mineralization.This area commonly develop wallrock alteration,mainly including quartz,pyrite and sericite alteration,they are closely related with gold mineralization. According to the output characteristics and spatial -temporal distribution of the deposit,we infer that Cuijia gold mine belongs to medium temperature hydrothermal filling type gold deposit.Based on these studies,we optimize four exploration target areas,among them,the depth and periphery of 1 and 10 veins have good prospecting of forming medium-scale gold deposit,it is worthwhile to conduct further exploration work.
