Chemical and physical weathering of primary minerals during the formation of laterite profiles in the Darling Range has formed distinct secondary mineral and morphological zones in the regolith. Erosion and human activity such as mining have exposed

The lateritic bauxite in the Darling Range of Western Australia is approximately 4–6 m deep and is composed of caprock (duricrust) and underlying friable bauxite developed from highly weathered granite and dolerite. This paper investigates the impa

Regolith materials beneath lateritic bauxite in the Darling Range of Western Australia mostly consist of highly weathered granite and dolerite. These materials become the substrate for establishment of vegetation after bauxite mining and their physic

The high strength of some regolith types can limit the growth of rehabilitated jarrah forest following bauxite mining in southwest Australia. Ripping mine floors to a depth of 1.5 m alleviates high strength zones and improves root exploration of subs

Crop yield in the sandy soils of the Western Australian wheatbelt is influenced strongly by the plant-available water (PAW) and strength of subsoils. The fabric of hard subsoils of fluvial and aeolian origin has been compared with that of in situ sap

A morphological key has been developed for regolith that is exposed during mining of lateritic bauxite in the Darling Range of south Western Australia. The key distinguishes materials with different mineralogical and chemical properties. Iron oxide c
