Geology Early Pleistocene sediments (Qp1 – see Geology and Geomorphology). Landform Weakly dissected high level terraces and alluvial fans. This unit represents the earliest Pleistocene terrace. Only remnants of these terraces survive, as they have been eroded away over the past 1.5 million years or so. These remnants may be found in the upper reaches of the Mitchell River and Perry River valleys. Soils Only a limited number of profiles have been examined and no samples have been taken for physical and chemical analysis. A typical profile is described below. |
0-10 cm | Very dark greyish brown (10YR3/2) loamy sand; gradual change to: |
10-25cm | Light grey (10YR7/2) loamy sand with quartz gravel; sharp change to: |
25-60+ cm | Yellowish brown (10YR5/6) finely mottled with light brownish grey (10YR6/2) medium heavy clay. |
