Numerous studies on the Meso-Neoproterozoic life evolution show that the cyanobacteria which thrived and dominated the biological world in the Proterozoic Era is closely related to the genesis of microbial carbonate rocks. Considerable oil and gas resources can be found in microbial carbonate rocks and many related oil and gas fields have been discovered on the earth up to now. The microbial carbonate rocks are widespread in China which are mainly found in Meso-Neoproterozoic, Cambrian and Ordovician System. Some of these rocks are proved to have great potential in hydrocarbon exploration and can be important hydrocarbon reservoirs. Oil and gas bearing marine carbonate rocks in China are primarily distributed in the Upper Yang Zi area in south China(Sichuan Basin), North China block(Bohai Bay Basin and Ordos Basin) and the Tarim Basin where the microbial carbonate rocks constitute considerable part of the deeply buried and ancient marine carbonate reservoirs. Among the strata related to the microbial carbonate rocks, there is great hydrocarbon discoveries in the Sinian and Triassic System in the Sichuan Basin, the Wumishan Formation of Meso-Neoproterozoic Jixianian System in the Bohai Bay Basin and the Majiagou Formation of Ordovician System in the Ordos Basin, as well as significant oil and gas show in the Sinian and Cambrian System in the Tarim Basin.
