Molar-tooth structures refer to the aggregations of equal-axised or polygonal microspar calcite with a crystal size of 0.01mm and a clear boundary, which are mainly developed in the Precambrian fine-grained carbonate rocks. The morphology of Molar-tooth can be divided into ribboned, nodular and clastic forms.
