Abstract: Yongxin gold deposit is located in the Heihe-Nenjiang tectonic melange belt in the northeast of the Great Xing'an Range, which is one of the newly discovered altered rock type gold deposit,and is controlled by the tectonic belt in this area. At present, there are few related studies on the genesis of the deposit and ore-prospecting prediction, and many geological problems are still unclear. This study on pyrite thermoelectricity in the deposit is to provide a basis for deep ore-prospecting. A total of 3 200 single crystal grains of pyrite ore samples from 32 drill holes were tested by the BHTE-6 type thermoelectric instrument,and the results show that the pyrite thermal conductance type is N type, which accounts for about 99%,and P type accounts for about 1%. The pyrite thermoelectric coefficient variation ranges from -306. 0 μV/℃ to 296.0 μV/℃. The ore-forming temperature of the Yongxin gold deposit calculated by the thermoelectric coefficient ranges from 190.2 ℃ to 313.5 ℃. The dispersion of pyrite thermoelectric coefficient, the distribution characteristics of conduction type, and the gradient of denudation rate and mapping of thermoelectric coefficient all indicate that the deep northwest part of Yongxin gold deposit still has a good prospecting potential.

Key words: Yongxin gold deposit, pyrite, thermoelectricity, denudation rate, ore-forming temperature
