Fluvial facies and shore facies are two different viewpoints on the origin of the Wutong Formation sandstone of the Upper Devonian in the eastern Hubei Province. Based on the abundant and elaborate field investigations and laboratory analysis, it is suggested that the Wutong Formation is mainly the pure quartz sandstone and glauconite-bearing quartz sandstone with great maturity. The curve of probability cumulating with relative steep slop shows that the sandstone is mainly made up of leaping components, some of which are made of the two-stage mode, and the contents of suspending and rolling components are quite low.  It can be concluded that the grain size parameter of sandstone is limited within the range of that of well-sorted shore sandstone. Microfacies and grain size analysis all indicate that the sandstone is significantly analogous to that of the high-energy clastic coast. The sandstones developed typically the shore-deposit structure, such as the flushing cross-bedding, great and asymmetrically wave-generated ripple and anomalistic concave. A sedimentary sequence is from the lower of the shore face zone to the upper of the shore face zone, foreshore zone and the backshore zone vertically, above of which there is a complete regressive sequence of shore sediments. The analysis on the paleogeography suggests that there was a shore environment in eastern Hubei province in the Late Devonian, which was perhaps open to the ancient Qinling Sea northward.
