Reason Sampled:

Soil contamination and environmental process evaluation; sampled to determine contaminant movement by heavy metals from the edge of an old rubbish dump

Description:

Old Marble Point construction camp site, approximately 50m north of Surko Stream, in the heavily disturbed area; much of the area has been modified by attempted burial of the trashed camp site

Geology

Geological setting:

The land surface is a gently undulating till plain formed by retreat of the Wilson Piedmont Glacier; The Marble Point region is an old landscape, as evidenced by deposits of phillipsite, buried soils and oxidised gneiss, which have been covered by advances of the grounded Ross Ice Shelf; later ice retreat and glaciological features have been controlled by changes in the stranded Wilson Piedmont Glacier; the till mantle is patchy and dominated largely by locally occurring rocks

Patterned ground:

Nil

Surface weathering or surface features:

Copper oxide on pipe surface and on surface of the soil

Soil

Soil parent material:

Sandy gravel till from predominantly marble and gneiss

Previous disturbance:

Considerable ground surface disturbance from tracked machinery during earlier site clean up; a major USA cleanup of the area in 1998/99

Soil weathering stage:

1 (Campbell & Claridge 1975)

Soil moisture status:

Oceanic subxerous, dry surface horizons but moist in lower horizons

Biological activity:

Nil observed at site
