Specimens illustrate deposition by intermittent drainage in a possibly migratory channel. Well-sorted quartz grains from a mature sediment were deposited with a carbonate mud as matrix in the channel and silty mud precipitated in backwaters. Intraformational mud pellets were deposited with a sandy mud matrix in places. Strong reaction between quartz clasts and an alkaline pore solution was active during evaporation of waterholes and during diagenesis. The solution evolved towards a calcic composition until after lithification was complete.
