Underlying the Shire of Dalwallinu is south west terrain which forms a part of the Yilgarn Craton. The area comprises of granite rock, gneissic banding and minerals rich in iron and magnesium.
The soils underlying the Shire of Dalwallinu includes loamy calcareous earthy soils, deep sandy and sandy earth soils, of yellow deep sand, yellow and brown sandy earths. Sodic subsoils of loamy and red loamy duplexes also occur in the area. The eastern portion of the shire is characterised by undulating sandplain, valley floors and a salt lake chain associated with an ancient drainage system. Emerging from the landscape are lateritic outcrop and broad sandy gravelly ridges. The western portion of the shire comprises of valley floors, salt lake chains and alluvial flats associated with an ancient drainage line, which is surrounded by undulating plain of sand dune and rises with long gentle gradients on weathered granite

Threatened Ecological Communities
Priority Ecological Communities
Red Morrel Woodland of the Wheatbelt
Tall open woodlands of Eucalyptus longicornis (red morrell) found in the Wheatbelt on lateritic, ironstone or granitic soil types. Sometimes found with Eucalyptus salmonophloia (Salmon Gum), or E. loxophleba (York Gum) woodlands and has very little understorey. It is also found directly above lake systems in the central and eastern Wheatbelt. The landscape unit in which it is found is valley floors, usually adjacent to saline areas.
