This book provides diversified and comprehensive sedimentary, stratigraphic, and paleontological information services in China both for scientific research and educational purposes. Although China has the largest number of 11 "golden nails" profiles in the world, few of them has internationally renowned profiles with only traditional sedimentary methods and means for outcrops, logging, and seismic analysis. It combines multiple disciplines such as sedimentology, stratigraphy, paleontology, geophysics, geochemistry, and methods such as big data and artificial intelligence to build open-source online digital platform of geological profiles. Based on the preparation and construction of a number of well-known classic sections of sedimentary geology at home and abroad, it has become an important platform for training of sedimentology talents.
