Torridon
DERIVATION:
Pre-Cambrian rocks of the Torridonian Formation.
TYPES OF PARENT MATERIALS MAPPED:
- Morainic deposits
- Glacial till
- Glacial drift
- Stony colluvial deposits
- Cryogenic deposits
COLOUR:
Reddish and pinkish till.
TEXTURE:
Till deposits are generally sandy silt loam with coarser textured (loamy sand) morainic material. Moderate stone content.
DOMINANT LAND USE:
Generally rough grazing with some forestry.
LANDFORMS:
Highly variable with morainic mounds within valley bottoms and lower valley sides and rugged valley terrain. Intermediate hill slopes, stepped or ridged with gentle or locally steep slopes.
SOIL CHEMISTRY:
Inherently acidic with low amounts of basic cations. Trace elements are generally low.
SOIL PHYSICAL PROPERTIES:
Potential rooting depth around 60cm with induration and/or rock acting as distinct barrier.
Weak structure development in subsoil.
