Figure F67. Predicted temperature profiles at Site U1352 based on the geothermal gradient established in the uppermost portion of the hole and variable thermal conductivity with depth. At 661 m CSF-A, the temperature gradient (dT/dz) is about one-half that of the above depth interval for sediments. The predicted bottom-hole temperature in Hole U1352C, assuming variable thermal conductivity with depth, is ~60°C, which is ~40°C lower than that obtained by assuming a constant geothermal gradient of 46.0°C/km.
