2020-07-29 A photomicrograph dataset of the Cambrian Miaolingian-Furongian carbonates at the Jiulongshan section in Western Shandong Province doi:10.11922/sciencedb.j00001.00095 en 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. The present database contains mainly 825 photomicrographs based on 104 thin sections. The photomicrographs were systematically described based on Dunham (1962) classification with modifications by Embry and Klovan (1971). The dataset consists of two subsets including columnar sections and photomicrograph, with a total size of 380 MB. The two sub-datasets are interlinked, providing a fundamental basis for a better understanding of the Cambrian carbonate depositional sequences and processes on the North China Platform. The dataset is helpful for basic geological education and research, and may also provide a basis for petroleum exploration, Artificial intelligence, science popularization, and other related work.
