	Morphological Notes
	A11	The top 1cm of the profile is loose and composed of extremely small aggregates and 
	single grains. Note the large amount of coarse fragments in this soil, predominantly 
	quartz, but others, too. Layer 3 has some colouring from the base of the
	A12	 A1, i.e. darker than the remainder of the B2 as exemplified by layer 4. Can the red 
	mottles of layer 3 and 4 be primary colours? i.e. the centre of ped. There are many 
	quartz coarse fragments at the B2-C boundary at 88cm. On the C-2C bound
	B21	ary there are large 22cm silt and quartz pebbles. Appears that layer 6 has been 
	truncated and the new pedisediment laid over it. Note the lack of carbonate in the C 
	horizon. C material is hard, whereas 2C rock is soft. 2C material remains w
	B22	hite/yellow and soft to bottom of core. Co-author McGarry. An ironstone band occurs at 
	110cm with silty material above it, no evident lime.
	Observation Notes
	Parent Rock: alluvial sediment, from sandstone, with lime,  Tertiary beds, weathered
	Site Notes
	Weak surface crust in fields - heaping or wash of material against the fence. Actually associated with edge of ploughed field. 
	? wind erosion on higher side.
