The deposit is controlled by fanlt and stratigraphy,principly bounded to the sheared zone which formed in a sequence of fine lithic tufls and carbonaceous shale in the contact zone between the tuffaceous and the andesitic sequence within Nafirdeib series.

The confirmation of the oolitic limestones of the Late Carboniferous to the Early Permian Age in the CMB of west Yunnan Province implied the carbonate succession was accumulated in a shallow and agitating environment, possibly as the carbonate caps of oceanic islands.

The Cambrian oolitic limestones in the Dabeiwang section in Xuzhou, Jiangsu are characterized by numerous layers,complicated textures and types and diverse morphologies.

Through dissolution kinetics experiment under normal temperature and pressure,this paper discussed dissolution kinetics characteristics and morphology evolution of oolitic limestone.
