	Morphological Notes
	A11	Colour for Horizon 2 is drainage mottle. Large cracks in subsoil faced with top soil sand, 
	extends through 171.03, 171.04. Carbonate nodules appear below 80cm. Approx. 60% 
	of core consists of red material. Horizon 5 has a fourth colour 7.5Y

	A12	R5/2, poor drainage. Prominent red colouring in subsoil again an indication of prior red 
	weathering; the grey is in fissures Residual Jurassic alluvium. One or two small 
	scattered pebbles in lower part of core.
	Observation Notes
	Parent Rock: residual, mixed texture, with lime, clay Pilliga Sandstone, weathered
	Site Notes
	Large shear vane will not penetrate. Very hard just beneath surface, which is hardsetting rather than crusted. Note red 
	paleosol in subsurface.
