Chromosol AU
A representative soil profile in a mapunit of grey, red, brown and yellow sands over clay or reticulite (mottled loamy sand). These soils are from the West Midlands of Australia. (Base photo provided by Department of Primary Industries and Regional Development, Agriculture and Food, Government of Western Australia.)
Topsoil:
Pale brown, red, yellow or white acidic to neutral sands between depths of 30–80 cm.
Gravel (<20 %) can be present usually at the base of the topsoil (sand) layer.
Subsoil:
Bleached sand layer can occur above clay layer.
Abrupt boundary between sand and clay layers or mottled reticulite.
Clay pH mildly acidic to neutral
Reticulite is strongly developed reddish, yellowish and greyish or white, more or less reticulately mottled horizons that can be hand-augered or cut with a spade. Ferruginous nodules or concretions may be present but are not diagnostic. When moist the material usually has at least a firm consistence strength, but following exposure the material may irreversibly harden. At depth it may grade into mottled saprolite.

In the Australian soil classification system, the soils in this unit are:
Dystrophic Yellow Chromosols, Sodic Eutrophic Brown Chromosols, Grey, Yellow, Brown or Red Sodosols, or Grey, Yellow, Brown or Red Chromosols.
Chromosols have a clear or abrupt textural B horizon and in which the major part1 of the upper 0.2 m of the B2 horizon (or the major part of the entire B2 horizon if it is less than 0.2 m thick) is not strongly acid.
Sodosols have a clear or abrupt textural B horizon and in which the major part1 of the upper 0.2 m of the B horizon (or the major part of the entire B horizon if it is less than 0.2 m thick) is sodic and is not strongly subplastic.

In Soil Taxonomy, these soils are primarily Alfisols or some are Aridisols. See the Caneyhead soil series for comparison:
