Using established dynamics model, the author has explained the genesis of numerous dolichos lablab limestone and siliceous limestone in the two growing stages of southern China, i.e. carbonates developing stages (Donggangling stage of middle Devonian and Changxing stage of late Permian). Because numerous carbonate rocks have been produced on the platform, at the same time, it is one of ignored material sources that numerous carbonate lime-mud have been transported from platform to basin.
