	265 there are clear gley colours in yellowish brown groundmass.
	Observation Notes
	Parent Rock: alluvial sediment, mixed texture, non-calcareous,  second terraced fan, Namoi
	Site Notes
	This site is 15-20m from a small drainage line (natural) which would account for the poor surface conditon and its sandy fabric.
