Geology
Geological setting:
The rock sample is from a boulder of old till, possibly Sirius Formation; the till is firmly consolidated but fragmented by weathering with fragmented clasts having been moved downslope approximately 2.5m; some of the clasts have oxidised outer surfaces; the till is fine grained with rounded to subrounded clasts
Patterned ground:
Nil observed
Surface weathering or surface features:
Rock surfaces are stained and the oxidised rhind extends >5mm below the rock surface
