	Morphological Notes
	A11p	The second colour in na02201 is sand grains, perhaps washed downslope. Na02202 is 
	a weak to moderate plough pan. The organic material in na02203 is a burnt (carbon) tree
	 root. Na02204 is 50:50 A and B, but is described as if B dominant. Na0
	A12p	2207 has abundant angular sandstone pieces - so is termed C, and sampled. Core 
	sample from 312 to 373cm was not found, so a sample was taken at 400-410cm. (The 
	comment is mute on this point but it seems that the missing part of the core was
	A13	 later found and sampled, see profile). Na02208 has moderately pedal clay in broad 
	vertical bands, associated with carbonate in pockets and bands. Na02209 is 50:50 
	carbonate band (vertical) and grey clay. The top of the profile is possibly 
	B21	colluvium from sandy beds at higher levels. Carbonate-rich Rolling Downs marl extends 
	from 30-200cm. It includes angular red (2.5YR5/6) sandstone and rounded quartz 
	fragments from 140-160cm, resting sharply on light grey (N7/) soapy siltsto
	B22	nes, with a prominent thick vein of white (10YR8/1) carbonate to 429cm. The soil is 
	poorly described as a black earth: more appropriately, no suitable group.
	Observation Notes
	Parent Rock: residual, clay, marl Rolling Downs Group
	Site Notes
	On a higher level than na017, with chalk and ferruginized stones scattered on the surface. A weak sandy clay crust covers 
	the surface.
