RLU key descriptions for the Sandstone and Sandstone Ridge Regolith-Landform map

The Regolith-Landform Unit (RLU) polygon codes provide a framework to present the regolith materials and associated landforms on the map sheet across the area. They are designed to first list the regolith lithology in capital letter codes, then landform in lower case codes. he modifier number following each RLU code allows for discrimination of variations within broader regolith-landform assemblages (typically due to differences in composition, vegetation assemblages or other attributes). The RLU codes are largely based upon interpretation of the dominant regolith-landform process responsible for their formation (i.e. genetic process), following the scheme of Pain et al. (i2000). Lithological and other RLU attributes are described in the map legend descrip-tions and accompanying map report.

RLU codes for regolith materials used here are: RLU codes for landforms used here are: A Alluvial sediments ah alluvial channel AC Alluvial channel sediments ap alluvial plain C Colluvial sediments aw alluvial swamp CH Sheetflow sediments ed drainage depression F Fill ep erosional plain (0-9 m relief) IS Aeolian sand er erosional rise (9-30 m relief) SM Moderately weathered bedrock (saprolite) el erosional low hill (30-90 m relief) SS Slightly weathered bedrock (saprock) m man-made S Weathered bedrock, grade indeterminate (saprolith) pd depositional plain ps sandplain

Sep5Rounded to sub-angular quartzose and lithic clast gravel and sand with muscovite. Minor red-brown quartzose sand and silt. Low-relief (< 9 m), low gradient, locally shedding sediment. Chenopod shrubland dominated by Atriplex vesicaria, Maireana spp. and scattered Casuarina pauper trees.

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satel-lite pseudo-colour image of the Sandstone and Sandstone Ridge Paddocks. Bands 3N, 2 and 1 (Visible Near Infra-Red) are displayed as red, green and blue respec-tively. The image highlights different regolith-landforms as a function of their regolith materials, vegetation types and amount of vegetation cover. In this image quartz lag-rich units stand out as white, ferruginised units appear in yellows and browns, depending on the level of ferruginisation and healthy green vegetation as red.

First Vertical Derivative (1VD) aeromagnetics of the Sandstone and Sandstone Ridge Paddocks combined from the BHEI (southern two thirds of image) and Koonenberry (northern one third) datasets from the Geological Survey, NSW Department of Primary Industries. 1VD normally highlights surface and near-surface magnetic features, here fault lines and ferruginised Sturts Meadows Siltstone. The Nundooka Range Fault runs diagonally from top left to bottom centre and a highly ferruginised band of silstone lies sub-parallel to this in the western part of the image.

Gamma ray spectrometric (airborne radiometric) image of the Sandstone and Sand-stone Ridge Paddocks from the Koonenberry dataset of the Geological Survey, NSW Department of Primary Industries, with interpretation. The radioelements potassium (K), Thorium (eTh) and Uranium (eU) are displayed as red, green and blue respec-tively. This image highlights Mesozoic and Neoproterozoic rocks and transported regolith cover in the west and Devonian rocks in the east, separated by the Nundooka Range Fault running diagonally from top left to bottom right. Devonian sandstone in the east has low emissivity and tends to be moderately eTh- and eU-rich. Adelaidean slates in the west have mostly moderate emissivity where saprolite is exposed except for a folded quartzite bed in the central south and eTh-rich ferrugi-nous float in the Sandstone and southwest Sandstone Ridge Paddocks. Cretaceous sediments in the far west and northwest moderate eTh emissivity.

Digital Elevation Model (DEM) of the Sandstone and Sandstone Ridge Paddocks derived from hand-digitised Fowlers Gap Field Station 1:25,000 scale topographic contours at 5 m vertical contour interval and the Shuttle Radar Topography Mission (SRTM) 90 m ground resolution pixel DEM. SRTM heights were used to fill in the 1:25,000 topographic contour heights where gaps of more than 50 m existed horizon-tally between adjacent topographic contours. The image is sunshaded from the north-east with a sun elevation of 30 degrees. The speckled appearance on areas of low relief is due to digital noise and levelling errors in the SRTM data.
