JA Daily Science Report for Expedition 304, 24 December 2004.
LOCATION: Site U1309 (prospectus site AMFW-01A)
Latitude: 30° 10.1195'N Longitude: 42° 07.1311'W
Water depth: 1645 mbsl
SCIENCE UPDATE: Cores U1309D-33R to -40R (181.1 to 219.5 mbsf, 71% recovery, 57% average recovery for hole) are moderately altered olivine-bearing gabbro with medium- to coarse-grained oxide gabbro and rare intervals of orthopyroxene-bearing gabbro, troctolite, and serpentinized peridotite. Evidence of deformation is rare and localized, and alteration is almost exclusively greenschist facies.
