assessment of environmental impacts from past human activities at Vanda Station; sampled for indications of

heavy metal contamination at a location where battery acid may have been discarded

1.6m east of the Vanda Station generator building and 2.5m to the north of the doorway to the building

cf. Notes for GEOLAND below

xerous; the soil surface is occasionally moistened by summer snowfall

SOIL MOISTURE STATUS

fractured, flaggy and in situ, granodiorite with accumulations of granular sand in the cracks between the angular, fragmented boulder sized clasts

SOIL PARENT MATERIAL

SURFACE WEATHERING or

SURFACE FEATURES

surface materials are angular and unstained

PREVIOUS DISTURBANCE

the surface has been heavily disturbed by base activities and was from the general area where battery acids were said to have been discarded

oil stained brown (10YR 5/3) sandy pebble to boulder gravel

coarse material predominantly tabular fractured granodiorite boulders

pale brown (10YR 6/3) loose sand filling fissures in fractured granodiorite

indistinct boundary,

pale brown (10YR 6/3) sand and rock fragments in fractured bedrock fissures.

FROZEN GROUND DEPTH(cm)

SOIL WEATHERING STAGE

the rocks of the area are granodiorites that have been cut with lamprophyre dykes and form a strongly undulating ridge and gully topography as a result of ice

over riding from down-valley and up-valley glaciations and to a lesser extent, subaerial weathering; at this site, the rock is fractured granodiorite; subsequent to

glaciation, the terrain has been subjected to drowning and emergence from fluctuating water levels from Lake Vanda with some sorting or resorting of surficial

materials
