Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A classification method for fine-grained mixed sedimentary rocks, comprising:
performing a core description, thin section collection and observation;
performing a mineral content analysis and a total organic carbon content analysis after micro-drilling sampling and mixing samples evenly, to obtain content values of different types of minerals and total organic carbon contents in the samples;
the different types comprising a laminated type and a fine-grained mixed sedimentary rock type;
dividing the laminated type into multiple laminar couplets types, to determine a mixed sedimentation of combination of different lamina or laminar couplets;
marking the total organic carbon content before the name of the fine-grained mixed sedimentary rock type; and
performing a systematic sampling of the fine-grained mixed sedimentary rocks with different types of sedimentary structures while avoiding diagenetic minerals via the core description and the thin section collection and observation, in the micro-drilling sampling.
