Figure F35. Thermal conductivity plotted with porosity for Holes 1219A (solid symbols) and 1219B (open symbols). An inverse relationship between thermal conductivity and porosity characterizes the nannofossil ooze (squares) but is weakly developed in the radiolarian ooze and clay (circles). Porosity values for Hole 1219B were derived from the GRA bulk density using the regression of porosity with GRA bulk density for APC-recovered sediments in Hole 1219A. Porosity = 132.8
