Geology
Geological setting:
The exposure is coarse grained micaceous granite
Patterned ground:
Nil
Surface weathering or surface features:
Upper surfaces of rock outcrops and boulders have moderate staining; some slight rounding and granular disintegration; a few salt efflorescences in patches on the soil surface; patches of finer material amongst more angular fragmented bedrock
Soil
Soil parent material:
Fragmented micaceous granitic sandy granular gravel from weathering of surface outcrops; patchy salts in the soils
light yellowish brown (2.5Y 6/4) sandy pebbly granular gravel; loose to weakly cohesive; weakly developed vesicular structure; scattered diffuse salt patches; rock particles angular, weakly to moderately stained and partly altered
