This map shows the soil parent material found at each National Soil Inventory of Scotland sampling location. This is the material in which the soils form. Parent material information is derived from the National Soil Inventory of Scotland (NSIS 1978-88) dataset.
The parent material is divided into the following categories:
|Aeolian - material deposited due to action of the wind|
|Alluvium - material deposited due to action of rivers or streams|
|Colluvium - material deposited due to down hillslope movement by creeping or surface wash|
|Cryogenic - material derived from the action of freeze and thaw processes|
|Fluvioglacial - material relating to or denoting erosion or deposition caused by flowing meltwater from glaciers or ice sheets|
|Moraine - mass of rocks and sediment carried down and deposited by a glacier|
|Organic - organic deposit|
|Raised beach - former beach now lying above water level owing to geological changes since its formation|
|Residual - unconsolidated rock material|
|Scree - accumulated debris that rest against the base of an inland cliff|
|Till - unsorted glacial sediment|
|Water-modified till - glacial sediment sorted through water actions|
|Not sampled - undefined parent material|
Parent material information is not provided as a separate dataset but is one of the National Soil Inventory of Scotland (NSIS 1978-88) dataset attributes.
