Analysis on geology condition of uranium mineralization and the exploration orientation for Baixingtu district southwestern Songliao basin

The paper mainly analyses the uranium mineralization conditions at Baixingtu district of southwestern Songliao basin. The research is focused on the characteristic of braided stream faces grey sandbody of Yaojia formation and the feature of epigenetic deoxidation and oxidization features of uranium mineralization abnormity, relation of uranium mineralization abnormity to fault, relation of uranium mineralization abnormity to interval oxidation, genesis of uranium mineralization and their controlling factors. It is considered that there are favorable metallogenic conditions in the Baixingtu-Donghuagen district of the east edge of Baixingtu denuded structure window for the formation of Qianjiadian type uranium deposit.
