	Morphological Notes
	A11	The clay pods in the parent sandstone have white carbonate in them. The associated 
	sandstone has no carbonate. Sandstone in situ is seen at 150 but there is no clear break
	 between pedisediment and parent sediment in situ. Colour 2 in layer 
	A12	6 is mainly faunal, but there are also infilled root channels and rock fissures. Note that 
	the carbonate in layer 6 is only in the infilled material.

	Project Name:	Soil Studies in the Lower Namoi Valley
	Project Code:	EDGEROI	Site ID:	ed415	Observation ID:	1
	Agency Name:	CSIRO Division of Soils (QLD)
	Parent Rock: colluvial sediment, sandstone, from sandstone, with lime Tertiary beds
	Site Notes
	Whole landscape is easy undulating (i2). Several pieces of angular and subrounded quartz stones. Some evidence of surface 
	run-off - shallow rills.
