?Quartzite cobbles and boulders set in fine quartzose sandstone and claystone.

Quartzite cobbles and boulders set in fine quartzose sandstone and claystone.

Flat to undulating plains covered by variable thicknesses of aeolian sand.

Playas, clay pans and lakes.

Alluvial gravel, sand, silt and clay.

Crossbedded, fine, medium and coarse-grained, quartz-rich and some quartz-lithic to lithic sandstone with subordinate interbedded fine sandstone, siltstone and mudstone. Quartz pebble and minor polymictic conglomerates are developed at a number of stratigraphic levels.

Crossbedded, fine, medium and coarse-grained, quartz-rich and some quartz-lithic to lithic sandstone with subordinate interbedded fine sandstone, siltstone and mudstone. Quartz pebble and minor polymictic conglomerates are developed at a number of stratigraphic levels.

Cross-bedded fine to medium grained, lithic-quartz sandstone occurring in two to three cycles with pebbly sandstone locally abundant in one cycle. Minor siltstone interbeds.

Cross-bedded and parallel laminated, medium to coarse grained, quartz-rich to lithic-quartz sandstone with recessive interbeds of siltstone and minor pebble conglomerate horizons (several upward fining cycles)

Interbedded cross-bedded, parallel-laminated, and massive, fine to coarse-grained, lithic-quartz sandstone and lesser siltstone. Unit is characterised by a prominent "ridge and terrace" topography.

Predominantly large scale cross-bedded, medium to coarse-grained quartzose sandstone, pebbly sandstone and pebble conglomerate. Minor basal pebbly granule conglomerate.

Massive to locally cross-bedded, fine to coarse-grained sandstone and lesser granule to pebble conglomerate. Pebbles are polymictic in composition (quartz, volcanic, tourmaline hornfels). Siltstone is present as recessive interbeds.

Cross-bedded, occasionally with ?hummocky cross-stratification, parallel-laminated and commonly ripple cross-laminated, well sorted, fine to medium-grained quartzose sandstone with lesser interbedded siltstone and mudstone.

Cross-bedded, parallel-laminated and rarely ripple cross-laminated, fine to medium-grained "flaggy" quartz sandstone interbedded with lesser siltstone. Sandstone is thin to thick bedded with ?hummocky cross-stratification locally.

Thick bedded, massive to planar-laminated and locally trough cross-bedded, fine to medium grained quartz sandstone interbedded with lesser siltstone/mudstone.

Thin to medium bedded, massive or graded, parallel-laminated and ripple cross-laminated, poorly sorted, fine to medium-grained, quartzose to quartz-lithic sandstone interbedded with siltstone and mudstone.
