Condamine is a Mesotrophic Effervescent Brown Sodosol (ASC) or Solonetz (WRB) developed on Cainozoic sand plains.
The soil varies considerably and includes: (a) contorted gilgai of fine texture (Dermosol); (b) Red-Brown and transitional Red-Brown earths (Kurosols) with sandy surface layers underlain by heavy clays; (c) Solodized Solonetz (Sodosols) with coarse-textured surface horizons, differentiated from the subsoil either by a well-developed and columnar structure; and (d) Deep Sands (Rudosol) that consist of undifferentiated reddish sandy loams.

Within this unit, several soil types were identified, including: (a) contorted gilgai, (b) red-brown earths and transitional red-brown earths, (c) solodized solonetz, and (d) deep sands.

The soil type at the Tarcoola Scald was a Yellow Sodosol (Isbell 1996) or Orthic Solonetz (FAO 1998), and a Yellow Sodosol (Isbell 1996) or Mollic Solonetz (FAO 1998) at the Tarcoola Depression and Tarcoola Vegetated microsites.
