The author suggests that the Zhiluo Formation belongs to the typical fluvial sedimentary facies, which cab be further refined to the channel, flood-plain and backswamp microfacies. 研究认为,直罗组属典型的河流相沉积,进一步可细分为河床亚相、河漫滩亚相和漫滩沼泽亚相。
In geology backswamp is the section of a floodplain where deposits of fine silts and clays settle after a flood. Backswamps usually lie behind a stream's natural levees.
