Coastal Plains of the Northern Territory.; Soils report
These reports describes the land resource mapping over the Northern Territory coastal plains region. The surveyed area was mapped at a scale of 1:50,000. The mapped land units are described using the dominate soils, topography and vegetation. The potential land use and limitations for each land unit are also briefly described.
There are three different reports attached to this record: Report on the land units of the coastal plains / K.J.Day; Soils of the coastal plains, Northern Territory, Australia / A.D.L. Hooper; and Soils report (coastal plains survey 1968,69,70 / K.J. Day

SUMMARY Land system surveys and detailed soil studies have been carried out on the Adelaide River plains, east of Darwin. These are low lying estuarine plains representative of extensive areas in coastal regions of the Northern Territory. Soil series were classified by the key characters of main layers of deposition: (A) Alluvial dark clays, (E) Estuarine clays, (G) Gleyed saline littoral clays, (F) Freshwater swamp clays, (L) sands and sandy clays derived from lateritic and sandy uplands (M) red and grey mottled sandy clays similarly derived. '1: Two environments of deposition are proposed, (a) the rivtrne environment in which A layers are mostly lime-rich clays succeeded by E and G layers with high salt contents dominated by sodium chloride. Drainage characteristics are inherited from former river channels. (b) the inland environment in which A layers are either low in salts due to the proximity of the sandy uplands or where A and E layers are often gypsum rich or have proportionally lower sodium chloride contents. These are underlain by F layers formed in paperbark swamp conditions similar to those prevailing at present.
