Abstract:
The Arpishmebulaq Formation is exposed at the eastern South Tianshan of Xinjiang and was originally proposed by E. Norin (1937, 1941), a Swedish geologist. It consists mainly of limestones and shales with a thickness about 400 m and yields abundant corals, brachipods, ostracods, stromatoporoids and conodonts. Norin subdivided it into 6 divisions (A, B, C, D, E, F).
