A single wash barrel was recovered from Hole 1160A (Core 187-1160A-1W; 0.0-166.0 mbsf). This core contains carbonate-rich clay and silty clay of varying color. Intervals range from 1 to 20 cm thick and vary from white silty clay, with a chalky texture, to dark brown clay, with rare light gray silty clay layers. From 0 to 45 cm in Section 187-1160A-1W-1 is a severely drilling disturbed interval. Below that, drilling disturbance is manifested by the bending of contacts downsection along core margins and by the smearing of intervals along the inside of the core liner. Nearly all contacts between intervals are sharp but irregular, some over as much as a centimeter. There are rare diffuse contacts, but these may be artifacts of rotary coring. All intervals effervesce in dilute HCl (~5%-10%). The bottom 5 cm of the core-catcher section contains lithified, subangular to subrounded, 1- to 4-cm-sized pieces of carbonate-rich sediment, with abundant millimeter-sized Mn oxide grains and one piece of palagonitized basaltic glass with adhered lithified sediment.
