IODP Expedition 330 Louisville Seamount Trail

Daily Science Report 24 -- Tuesday, 4 January 2011


Site U1373 on 28.6°S Guyot 28° 33' 55.8" S, 173° 16' 46.8012" W
Louisville Seamount Trail
0 m above sea level

Cores U1373A-12R (56.0-60.7 mbsf) and -13R (60.7-65.7 mbsf) were retrieved with 61% and 88% recovery. The lithology continues with well-preserved, medium gray, aphyric basalt (lava flows). In contrast to the previous cores, the rocks are highly fractured and show a distinct magmatic foliation. At noon, the series of site summary meetings for previous Site U1372 were concluded by presentations from the Geochemistry and Paleomagnetic lab groups. The necessity of the scheduled drill bit change in the evening provided a welcome opportunity for all lab groups to catch up with core descriptions and shipboard measurements.
