| Abstract: | Mantou Formation of the Lower Cambrian in Taitze River Basin can be aiviaea into 4 facies belts, namely, supratidal gypsum--dolomite facies, supratidal dolomite facies, intertidal limestone--dolomite facies, subtidal micaphyre--limestone, belonging to carbonate tidal flat deposits in barrier--sea. Anhydrite deposits formed in sabakhas under the conditions of dry and hot environment. The palaeogeographic environment favourable to ore--forming is the place in front of palaeo--islands. |
