JA Daily Science Report for Expedition 312, 18 December 2005


LOCATION: Site 1256


SCIENCE UPDATE: Cores 230R to 233R recovered 10.4 m of highly altered medium grained gabbro crosscut by several ~1 to 2 cm wide felsic dikelets from 1483.0 to 1502.5 mbsf at an average penetration rate of 1.3 m/hr. The gabbros contain several cm-scale basalt inclusions, possibly stoped from the sheeted dikes above.
