Pyrite is the most common metal sulfide mineral in mineral deposits，mostly formed at the stages of uranium mineralization. Its typological characteristics have important indicative significance for deep mineral exploration and prediction. This article uses electron microscopy，powder diffraction，thermoelectric analyzer，and electron probe system to analyze the typological characteristics of pyrite at different mineralization stages and elevations in the Shulouqiu uranium deposit. The research results show that the n（S）/n（Fe） values of pyrite in this area indicate a deficiency in S characteristics. Analysis of characteristic elements such as δFe，δS，As，Se，Co，Ni，etc. shows that the genesis of pyrite in this area is mainly magmatic hydrothermal. The characteristics of the crystal cell parameters of pyrite indicate that the substitution of S with As in a isomorphic form is the main cause of the increase in a0 and also an important factor leading to the precipitation of U element. The thermoelectric coefficient value （a）of pyrite is -301.0~332.2 μV·℃-1，and the thermal conductivity type is mainly P-type. The formation temperature of pyrite is 74~386 ℃，belonging to a medium low temperature deposit. The thermal electric coefficient dispersion （δa′）of pyrite indicates a mineralization period with a δa’of 82.1，indicating a relatively stable mineralization environment and a weak degree of superposition；The δa’values in the early and late stages of mineralization are 201.6 and 224.9，respectively，indicating that they may have been formed by the superposition of multiple stages of hydrothermal fluids，with a relatively high degree of superposition； The δa′ values at each stage gradually decrease with the decrease of levels，and are relatively concentrated，indicating that the mineralization become relatively better as the depth increases. The thermoelectric parameter Xnp of pyrite is -40.0~61.0，and the erosion percentage（γ） of the ore body is 34.8 %~60.0 %，with an average of 48.9，indicating that the deposit has been eroded to the middle and still has significant extension in the deeper part. Comprehensive analysis suggests that there is still good mineralization and prospecting potential in the deep part of the deposit.
