Abstract: Luanchuan Yuku molybdenum deposit is located in the southern margin of the North China Craton, whose Yanshanian magmaskarn type mineralization is related to the large concealed Mo polymetallic deposit discovered in recent years. The samples from deep drilling mining (>1,000 m) were used to analyze thermoelectric characteristics of pyrite and the aim was to provide an important scientific basis for the exploration of deep prospecting in this area. The research contents and methods are as followed:the thermoelectric properties of pyrites are mainly of the N type with a total content of 96%.The thermoelectric parameters characteristics reflect the orebody denudation to the middle and lower position, but the statistical data shows the depth potential extension. According to the pyroelectricity of pyrite ore in the study area to calculate the forming temperature of fan between 270-332 ℃, the deposit belongs to shallow medium temperature hydrothermal mineralization. On the basis of geological statistics, ArcGIS Geostatistical Analyst modular was used to analyze the trend of metallogenic temperature, and the oreforming regularity and potential targets were discussed.
