Some of the fragments show excellent cellular structure indicating the presence of coral, gastropods and bivalves. Other shelly fragments consist of very fine grained carbonate. Pyroxene grains (<5%) are colourless, angular and less than 0.2 mm across. There is a trace of spinel, minor angular feldspar (less than 0.2 mm across) and brown clay.
