Antrim 5 (AS) Rounded Structural basalt bench hill Minor Minor ! clay plain Lower' stream slope channel ~ ~ v v \I " V v v Province - 3,4,6 Geology - Antrim Plateau volcanics. Landform - Rounded basalt hills and structural benches with 80-100% outcrop. Slopes commonly 2 to 10 but locally to 30. Relief commonly 80 ft but rises to 120 ft. Minor lower slopes and high level sedentary clay plains. Soils - Mainly stony skeletal red earths, (loamy) with some outcrop. Minor brown clay inclusions on flatter areas. Vegetation - On skeletal volcanic soils, E.brevifolia forms a low open woodland association over T.roscida and T.inutilis. In areas where the tree cover is sparse, T.roscida occurs alone as a Hummock grassland. On cracking clay soils the tree cover is sparse and variable (mainly E.brevifolia or T.arostrata), and the spinifexes are replaced to a large degree by other annual and perennial grasses: Iseilema, Sehima, Eulalia, Dichanthium. - 56
