The white sandstone is a medium grained, poorly sorted, trough cross-bedded braided fluvial channel.

Immature stage: The sediment contains more than 5% clay and sand grains are poorly sorted and angular.

Submature stage: The sediment contains less than 5% clay and sand grains are poorly sorted and subangular to subrounded.

The upper Ocala is white and somewhat weak and poorly sorted.

The first wave of sediments were coarse, gray, and poorly sorted.

Poorly sorted at base, influxes of coarser material.

Mammal fossils are rare in Cornwall and a dog was found within the poorly sorted, course-grained sediments of head dated to 12,000 to 15,000 years ago.

Evidence for this can be found in the north Atlantic sediment cores which show poorly sorted, angular and contain rocks.

Poorly sorted sandstone and concretionary beds also occur.

Wadi deposits are thus usually poorly sorted gravels and sands.
