LOCATION: Site 1256


SCIENCE UPDATE: After deploying the new bit and washing and reaming to bottom (10 m of fill), Cores 222R to 225R recovered 5.05 m of highly altered medium to coarse grained gabbro and highly altered fine grained aphyric basalt from 1444.6 to 1463.9 mbsf. Unit 89 ends with a rapid grain size decrease toward the bottom of Section 223R-2 and continues in three small gabbroic cobbles in Core 224R. Unit 90 consists of three small fine grained highly to completely altered basalt fragments in Core 225R.
