Isotope Cyclic Stratigraphy of Permian and Triassic Transitional Periods in Southern China - Carbonate formation comparison and Index Genesis Interpretation (Chinese Edition)

The crossing of Permian and Triassic Transitional Periods is an important turning period of biological and environmental changes in the history of the Earth. At that time, the largest-scaled biological mass extinction events in the history of the Earth take place. As the study on its origin has important enlightenment significance on the coordination of relationship between man and nature. It has been a hot research field in recent years. This book makes a high resolution carbon and oxygen isotope stratigraphic study on the carbonate rocks in Southern China from Late Permian to Early Triassic periods. It makes achievements and innovation in isotope cyclic stratigraphy identification, sets up the high-precision division and comparison model for carbonate formation, and makes significant progress in using stable isotope to interpret the carbonate formation environment. The carbon and oxygen isotope and sedimentary records show that at the end of the Permian period, the marine is an anoxic environment with a large number of hydrates. And the biological mass extinction may be associated with the quick release of gas hydrate from submarine. This book can be a good reference for researchers engaged in sedimentary environment, geochemistry, carbonate formation and paleontology as well as relevant college teachers and students.
