Figure F68. Thermal conductivity measurements on Expedition 345 samples compared with data from previous Ocean Drilling Program (ODP) and Integrated Ocean Drilling Program (IODP) gabbroic cores. Curves are compiled data from fast- and slow-spreading crust at Hess Deep ODP Leg 147 Site 894, ODP Hole 1256D, ODP Legs 118 and 176 Hole 735B at the Southwest Indian Ridge, the Mid-Atlantic Ridge at Kane area, the Mid-Atlantic Ridge in the 15°N area, and IODP Expedition 304/305 Site U1309 (Atlantis Massif) on the Mid-Atlantic Ridge at 30°N (Shipboard Scientific Party, 1989, 1993, 1999, 2004; Cannat, Karson, Miller, et al., 1995; Expedition 304/305 Scientists, 2006; Expedition 309/312 Scientists, 2006). Large circles and horizontal bars show the average and range of thermal conductivity values, respectively.
