摘要： The present disclosure discloses a classification method and system for fine-grained mixed sedimentary rocks, a medium and a terminal. Core description and thin section observation are used to accurately identify the sedimentary structure types and their vertical distribution characteristics from the macroscopic and microscopic perspectives, and indicates the mixed sedimentation characteristics of combination of different lamina or laminar couplets. The micro-drilling sampling technique is used to sample the samples with different types of sedimentary structures while avoiding diagenetic minerals. X-ray diffraction mineral content analysis and a high-precision carbon-sulfur analyzer are used to obtain the contents of different types of minerals and the total organic carbon contents in each sample, respectively, the basic rock type of each sample was determined using a triangular classification diagram. The name of sedimentary structure and the total organic carbon content are added in order before the name of the basic rock type.
