On the base of the application of transient electromagnetic technique of paleochannel-type sandstone-hosted uranium deposits in Tengchong region of Yunan Province, This paper analyses the detect example.

Analysis on depositional system and discussion on ore-formation conditions of channel sandstone type uranium deposit--taking Dongsheng area,Ordos Meso-Cenozoic basin as an example;

On the base of the deposit researching,it is concluded that basal-channel sandstone-type uranium deposits with roll front must need two conditions: the first is the metallogenic sandbody has better stratified,connectivity and permeability;the second is the stratigraphic frame must be have better water-resisti.

This paper systematically introduces the geologic background,characteristics of uranium mineralization and uranium metallogenic conditions of the three regions in Russia(Transural,western Siberia and Transbaikal regions) where important paleochannel type uranium deposits have been discovered.

A method of quantitative prediction for sandstone type uranium deposit in Russia and its application;

Analyses on anomaly of radon and its daughters above sandstone type uranium deposit;

3D groundwater flow simulation in a sandstone type uranium deposit in-situ leaching field;
