Geology
Geological setting:
The deposit probably represents older and more weathered material derived from local granitic and meta-volcanic rocks; the apparently finer texture at this location may indicate some accumulation of wind- blown material
Patterned ground:
Nil
Surface weathering or surface features:
Surfce rocks show some oxidation; salts are present beneath some clasts; the soil material is distinctly crusty but this appears to be due to partial solution crystalisation
Soil
Soil parent material:
Partly oxidised granitic detritus with some fine fraction accumulation
brownish yellow (10YR 6/6) gravelly silty sand; loose but cohesive in places; weakly developed vesicular structure with some particles appearing bonded with non-calcareous material; rock particles subangular to subrounded and partly altered; distinct cohesive salt accumulations underneath some profile clasts,
