Most of the hinterland of the North China platform is devoid of Late Ordovician strata. The Baiyanhua Mountain section at Shetai Town is a standard section of the Upper Ordovician newly established in recent years at the northernmost margin of the platform. This establishment directly involved the determination of the north boundary of the platform and the understanding of its evolutionary history. The area is quite different from the hinterland of the platform in Middle Ordovician rock types and sedimentary environments, with the former characterized by frequent slope deposits and the latter consisting almost entirely of platform deposits. The present paper focuses on the petrographic features and sedimentary environments of the Middle‐Upper Ordovician strata in the area, providing further theoretical support to the establishment of the section and filling the gap in this respect.
