The latter is further sub-divided into gravelly and sandy braided fluvial facies.
From Paleocene to Miocene, the sedimentary facies evolved from the extensive alluvial fan to the braided fluvial river environment.
There are two types of sedimentary facies in this region: the alluvial fan and the braided fluvial river.
Major sedimentary facies in the Luohe Formation include alluvial fans facies, eolian facies,braided fluvial facies, and desert facies.
