Molar-tooth carbonatites can be found in almost all the Neoproterozoic carbonatite strata in Northern Anhui and Jiangsu Provinces. According to their features in different strata, two molar-tooth carbonatite types can be differentiated in this area. Type 1 molar-tooth carbonatites coexisted with stromatolite bioherms, gravels, debris, slump structures, swash channels and hummocky crossbeddings, were formed in the upper Liulaobei Formation and Jiuliqiao Formaiton which belong to the lower Neoproterozoic in this area. Type 2 molar-tooth carbonatites consisted in widely spread rhythmic units with graded beds and typical erosion surfaces, were formed in other Formations which belong to the upper Neoproterozoic in this area. The initial forming power of the molar-tooth carbonatites in this area might be the crustal movements which were caused by the break-up of the Rodinia. Type 1 molar-tooth carbonatites formed in tempestuously changing environments might be a signal of the break-up prelude of the Rodinia, while Type 2 molar-tooth carbonatites formed in steadily, periodically changing environments might indicate the intermittent release of the earth stress during the break-up period of the Rodinia.
