A single wash barrel containing a slurry of drilling-induced clay pellets was recovered from Hole 1161A. The pellets range from submillimeter to 2 mm in size, and the sediment is poorly sorted but normally graded as a result of agitation in the core barrel. The sediment is a mixture of medium brown and medium dark brown siliceous clay with no calcareous component. The upper 4 cm of Section 187-1161A-1W-CC is comprised of fragments, up to 2 cm, of severely drilling-disturbed, densely packed, medium brown and medium dark brown siliceous clay. Five small pieces of basalt were recovered from the bottom of the core catcher.
No sediment was recovered in the wash barrel from Hole 1161B.
