Molar tooth carbonate is a special sedimentary rock, which has been widely found around the world, such as Europe, North America, Africa and Asia. The features and genesis of molar tooth carbonate are still the focus of the sedimentary study so far. The molar tooth carbonate has an important significant for the stratigraphic correlation, sedimentary condition and paleoenvironment. In the Benxi area, the discovery of the molar tooth carbonate in the Nanhua System has a great meaning to study the Precambrian geology of the Jiao-Liao Block, then reconstruct the Neoproterozoic paleogeography of North China Craton. In the last decade, the methods of geochemistry have been widely used to solve geological problems, for example petrogenesis, tectonic evolution, dynamics and so on. The main geochemistry method of carbonate is C-O isotope analysis, which can suggest the feature of ancient water temperature. It also can be used to identify the history of oxidation event or glaciation. There are some evidences show that molar tooth carbonate has relationship with oxidation event and glaciation. The oxidation event and glaciation can change and reflect the setting of paleo-ocean environment and then influence the diversity of marine lives.
