Abstract: Wall rock alteration of the Huanggou Mine includes chloritization, hydromicazation, hematitization, sericitization, Kfeldspar alteration, sulfurization and carbonation based on a large of researches combined with microscope analysis. The typical alteration mineral assemblages of the uranium mineralization are chlorite+quartz, chlorite+hydromica+quartz, chlorite+saussurite+quartz and chlorite+hydromica+hematite+quartz. The hydromicazation is earlier than the period of uranium mineralization, and provides a better environment for it. The chloritization and hematitization of the accompanying mineralization of alteration take place lately. Highgrade ore is related to the hematitization, chloritization and hydromicazation. Hematitization and chloritization play an important role in the uranium mineralization. Moreover, the higher intensity, the more type and times of the ore wall rock alteration, the richer uranium mineralization is.

Key words: Liaoning, uranium mineralization, wall rock alteration, combination of elements
