| The formation is composed of red siltstones, containing discontinuous calcrete horizons, channelized sandstones and thin beds of current-rippled fine sandstone. |
| The Yellow Cat Member contains a basal calcrete with interbedded sands and clays and extends upward to a prominent sandstone unit. |
| The brow bone, however, turns out to be a calcrete deposit often found in caves. |
| Thin coals mark periods of swamp conditions on the floodplain, although some palaeosol profiles suggest relatively well-drained conditions, including a thin calcrete. |
| The region's Mediterranean style climate and annual water deficit has led to extensive calcrete development. |
| The more water soluble duricrusts, such as calcrete and gypcrete, can have solution holes or pits. |
