Geology

Geological setting:
Mt Mooney is predominantly metavolcanic but the north side is granite, predominanly pink and coarse-grained, probably intrusive; the lower slopes of Mt Mooney are partly scree covered but many boulders at the foot of the slope are moderately stained; there are signs of ice ablation having exposed surfaces with previous weathering features
Patterned ground:
Nil
Surface weathering or surface features:
Some oxidation on surface boulders; fretting of micas from exposed rocks
