摘要
The Huachanggou gold deposit in Shaanxi Province mainly occurs in the submarine basic volcanic effusive spilite.On the basis of a study of the thermoelectric characteristics of pyrite,the authors put forward the following conclusions.The main ore zone is a low-medium temperature gold deposit,whose pyrite crystallization temperature is in the range of 130-330 ℃.The electric conduct assemblage type of the pyrite changes in the order of N-type to P-type from the early stage to the late stage.The frequence of P-type pyrites gradually decreases from the shallow part to the deep.The high average gold grade corresponds to the high frequence of P-type pyrites and low value of thermoelectrical coefficient dispersions.The characteristics of thermoelectricity imply that the lower to middle parts of the ore body have been exhumed until now,and there exists an extension of the main ore zone in the deep.Furthermore,the authors suggest that the better exploring prospect would be expectable in the depth of exploration line Nos.0,2 and Nos.22-26.
