	A1	Sharp break at 165cm marks limit of pedisediment. The break is succeeded by 10cm 
	sands and subangular fragments of sandstone and argillite. 2.5YR4/6 at 250-260 is 2-
	10%, the central colour of the peds. 250-260 has 2% 7.5YR2/0 charcoal, most

	 non-calcareous sand to calcareous sandy clays at 60cm. A solodic soil with ?aeolian 
	lime on pedisediment over weathering sandstone, the whole profile
