Abstract The sandy dolarenite of the Sinian Doushantuo Formation in the eastern Yunnan Province is a typical example of hunji rock, a mixed sediments in narrow sense. All sand grains are quartz sands. Sorting and roundness and sphericity of particles are in good grade level Quartz sands are scattered in microcrystalline dolomitic sands in “floating” state. The occurrence and texture and structure of sandy dolarenite show that the beach sands was transported into to the sea in the process of transgression, and mixed with dolomitic interclastics.
