- An array of different soil parent materials exists within Scotland, the direct result of different
phases of glaciation.
- Soil parent materials fall into
different groupings.
- Shattered rock or rock in situ
- Glacial drift (unsorted, weathered
mineral material moved by ice), including
colluvium
and solifluction deposits.
- Lodgement till being ground up rock
material characteristically unsorted,
deposited by
ice.
- Water-modified glacial till with the
upper soil horizons of coarser texture
than the
underlying till.
- Fluvio-glacial meltwater deposits of
sand and gravel and in highland areas,
morainic
deposits.
- Mountain-top detritus; frost shattered
debris with common rock and scree.
- Recent deposits, including Aeolian
sand, alluvium raised beach deposits,
peat and
saltings
- An association represents a grouping
of soils developed on the same or similar parent material e.g.
Countesswells Association includes glacial drift derived from granite
or granitic rock.
- There are 144 associations mapped within Scotland, the 15 most
extensive are listed below.
