Geology

Geological setting:
In the lower half of the Shackleton Valley, granites of the Granite Harbour Intrusives occur and tills are more varied in composition with Beacon Group sediments, dolerite and granite being the main components; the tills are young; because the climate is warmer, small streams and meltwater pools are present
Patterned ground:
Nil
Surface weathering or surface features:
Bouldery surface with little staining or weathering; no surface crust

Soil

Soil parent material:
Young till from sedimentary rocks, granite and dolerite
Previous disturbance:
Nil
Soil weathering stage:
6 2 (Campbell & Claridge 1975)
Soil moisture status:
Xerous to subxerous; some water flowing in a nearby small stream
Biological activity:
Nil observed
Profile Description
HorizonDepthDescription
96a 0 – 10 cm pale brown (10YR 6/3) cobbly silty gravel; loose; few fine salt flecks; many rock particles covered with silt coating; rock particles angular to subrounded and mainly unstained; indistinct boundary,
96b 10 – 30 cm pale brown (10YR 6/3) cobbly silty gravel; loose; weakly developed vesicular structure; thin silt coatings on many rock particles; rock particles mostly angular to subrounded and unstained but some granite and dolerite particles moderately stained and partly altered; distinct boundary, on bouldery till
