Interlayered oxidation type sandstonehosted uranium deposit is one type of the uranium deposits. It is totally blind or concealed, which makes it is difficult to be detected. As one branch of the deeppenetrating geochemistry, the electrogeochemical prospecting has become an important and effective method and accomplished a lot of achievements in exploration for deepburied uranium orebodies. Many studies indicate that there are existing electrogeochemical anomalies over known sandstonehosted uranium deposits. The physical and chemical formation conditions of interlayered oxidation type sandstonehosted uranium deposit are summarized and analyzed. Electrogeochemical characteristics of U is introduced over known uranium deposits. Formation mechanism of electrogeochemical anomaly is introduced based on the known migration mechanisms and field results. The U ore body is manifested as jumping U electrogeochemical anomaly of U detected directly above, which can be regarded as prospecting indicator for concealed sandstonehosted uranium deposit.
