Abstract: The Tertiary in the Aerjin Slope in Caidam Basin is characterized by strong carbonate recrystallization,weak compaction, weak quartz overgrowth and enrichment of the early-stage carbonate. The carbonate ce-ment,influenced by the salinity to some degree,is mainly inorganic with few relation to biogas. In muds clayassemblage is illite-illite/montmorillonite-chlorite. With the increase of depth the relative content of illite fluc-tuates and that of chlorite decreases. The illite may be terrestrial origin.
