Near Nature's Valley, South Africa, alluvial fan and braided-stream sandstones and conglomerates occur as a thin veneer unconformably overlying the Cape Supergroup's heavily weathered Ordovician Table Mountain strata. These deposits are similar to the Enon Formation of the Mesozoic Uitenhage Group. Two distinctive facies are recognized in outcrop: gravelly braided-stream and interbedded alluvial fan conglomerates and sandstones of mid-fan to distal fan affinity. Proximal alluvial fan deposits are not present. Clast-supported, structured pebble-boulder conglomerates with sandstone matrix dominate the braided-stream facies. Stratification and clast imbrication are common. The conglomerate clasts are mainly quartzite originating from the Table Mountain Group strata upon which they rest. The mid-fan to distal fan deposits are represented by interbedded cobble-boulder conglomerates and sandstones, mostly with erosive bases and with beds of a short lateral extent. A basal-lag boulder and cobble conglomerate grades upward to reddish, medium to thick sets of cross-bedded sandy conglomerates that pass upward to medium and fine-grained sandstone. The sedimentological characteristics and location of Nature's Valley fan suggest that its development was more influenced by tectonics than by climate fluctuations. The evolutionary history is likely to be dominantly a result of accumulation close to the foot of an active fault scarp.
