JA Daily Science Report for Expedition 309, 26 July 2005


LOCATION: Site 1256


SCIENCE UPDATE: Hole 1256D was reentered after the bit change for the fourth time. The drill string began taking weight at 4525 mbrf (880 mbsf) so the pipe was picked up to 4523 mbrf, a core barrel dropped, and the hole was washed and reamed to bottom. Coring has resumed from 897.8 mbsf. The first shipboard ICP analyses confirm that the cores recovered are actually basalt. XRD analyses confirm the presence of laumontite and anhydrite in veins.
