Abstract:?The North China Platform was a typical epiric platform during the Cambrian. A variety of carbonate facies developed in the North China Platform during Cambrian Miaolingian-Furongian. This database contains mainly 825 photomicrographs of 104 thin sections. The photomicrographs were systematically described as per Dunham (1962) classification modified by Embry and Klovan (1971). The dataset consists of two subsets storing columnar sections and photomicrograph, respectively, with a data volume of 390 MB. The two subets are interlinked, providing a fundamental basis for better understanding the Cambrian carbonate depositional sequences and processes on the North China Platform. The dataset can be used for basic geological education and research, and may also be useful for petroleum exploration, artificial intelligence, science popularization and other related work.
