	Morphological Notes
	A11	Brigalow 6 is the original site 4, missed on the first pass. The gypsum forms a band from
	 10-24cm; pores at 70-80cm form an ants nest. Second core is very, very hard to cut. At
	 about 200cm the core becomes steadily sandier, without slickens
	A12	ides (the last slickenside being at 190). This suggests that the sediment is alluvium. The 
	major part of the segregation is carbonate, but some gypsum is present. 270-280cm 
	was sampled by mistake for 250-260cm, no change in morphology. Ped 
	A13	faces at 475-520cm show surface horizontal striations, proving relative movement of 
	soil along structural faces. There are only a very few concretions at 560cm. Note 
	slickenside at 575cm. 350-360cm includes inwashed sand. The buried altered
	A14	 prior soil might start at 85cm (i.e., burials 2 & 3 might be the same); it is difficult to pick 
	the contact but the profile seems to be sandier below 85cm.
	2A	horizon contains an inherited lithological discontinuity
