Sedimentary Geologic Character of
///Mo, Ni, V and other polymetals in black rock series in Meishucun period in Early Cambrian in Guizhou close relationship with sedimentary environment, formed different polymetal associations: clayrock Mo, V ore, iron pyrites Ni, Mo ore and clayrock V ore. They distributed in sedimentary facies areas and may be the outcome of sedimentation of deep materials in close sea area.
