Based on color synthesis, textural analysis, image interpretation and extraction of concealed information, the authors interpreted the outcrop regions of Bayanhua Formation (K1b), the basin-controlling NE-trending faults (F1, F2, F3), the NNE-trending faults (F21, F20), the NW-trending faults and the nearly EW-trending faults, and updated the geological map of Bayantala basin, Inner Mongolia. An analysis of the information of paleochannels and geomorphology revealed the features of neotectonics. The recharge-flow-discharge characteristics of groundwater in relation to uranium mineralization were studied by extracting information of rock heat radiation and plant cover. On the basis of the above research, it is considered that the distribution of facies zones of Tenggeerian fan-deltas near the southeastern margin of the basin is controlled by F3 and F2; the pattern of Saihantalaian paleochannel is controlled by F2, F21and NW-trending faults, and the phreatic and phreatic-interlayer oxidation zone is controlled by the fault-block uplift generated by the combined action of NE-trending, NW-trending and nearly EW-trending faults.
