Land Resources of Auvergne Station A supplement to the Land Resources of the Victoria River District 13 The source and age of the colluvium has produced a high degree of variability in soils. These vary from deep siliceous sands (Tenosols) generally found at the bases of sandstone rises and hills, to non-structured and structured brown and red earths (Brown and Red Kandosols and Dermosols) across the older and flatter plains further inland. Rock outcrop is generally minor and the gravel variable. Vegetation communities across colluvial landscapes are also highly variable. Corymbia polycarpa (Long-fruited bloodwood), Corymbia confertiflora (Broad-leaved carbeen) low open woodlands are widespread to the south. Eucalyptus pruinosa (Silver box), Terminalia platyptera or Melaleuca minutifolia (Teatree) low open woodland/shrublands are also prevalent and tend to occur further inland on the property. Siltstone The siltstone lithology group is a similar landscape to the sandstone and it is dispersed in small blocks throughout the eastern part of the lease where sandstone and colluvial landscapes are common. These areas are generally rises and plains with very shallow (Rudosols) or texture contrast (Chromosols) soils. The vegetation communities are commonly Melaleuca sericea, and/or Melaleuca minutifolia (Teatree) low open woodlands/shrublands with a Triodia bitextura (Curly spinifex) and Sorghum sp. understorey. The Pinkerton Range is also layered with siltstone and sandstone; both are evident on steep sideslopes. This layering can be seen near the junction of the Duncan Road and Victoria Highway. Calcareous Material A small calcareous plain exists on the boundary of Nagurunguru ALT (Amanbidji) and Auvergne; the soils are cracking grey clays (Vertosols) with abundant surface limestone rock and rock outcrop. The vegetation is a typical Bauhinia cunninghamii (Bauhinia), Corymbia terminalis (Bloodwood) mixed species open woodland commonly found on these landscapes.
