Huachanggou Gold Deposit is hosted in the strata of the Devonian Sanhekou Group,strictly controlled by tectonics.To guide the deep exploration of the AuⅠ ore body,the deep pyrite samples of the AuⅠ ore body in Huachanggou Gold Deposit are systematically collected and analyzed,and the metallogenic temperature,denudation rate,thermoelectricity,and thermoelectric parameters of pyrite are studied.The results show that the denudation rate of AuⅠ ore body is 19 %-26 % in the existing tunnels,and gradually increases over more than 30 % towards the deep.The thermoelectric conductivity types are mainly P-type and N-type respectively,and the thermoelectric coefficient of pyrite varies from -201.20 μV/℃ to 901.20 μV/℃.The analysis shows that the thermoelectric coefficient of AuⅠ ore body is high in the middle section of 910-830 m,indicating that the thermoelectric conductivity type is mainly P-type.The sample data collected in deep boreholes show that the thermoelectric coefficient of pyrite has an obvious increasing trend.The thermoelectric conductivity type of pyrite has the characteristics of P-N type conversion from P-type,indicating that the AuⅠ ore body is still in the shallow position at this stage,and there is a large extension in the deep.It is speculated that Exploration Line 64-112 has good prospecting potential.
