From: Thermal conductivities, thermal diffusivities, and volumetric heat capacities of core samples obtained from the Japan Trench Fast Drilling Project (JFAST)

Figure 6

Depth profiles of thermal diffusivity (A) and volumetric heat capacity (B). Thermal diffusivity (A) was estimated using the empirical equation proposed by Hyndman et al. (1979) from the measured thermal conductivities of 45 half-core samples (open squares) and 38 rock-chips samples (open triangles), and the measured values for the four whole-round core samples (red circles). Volumetric heat capacity (B) was calculated using the measured thermal conductivity and estimated thermal diffusivity (open squares and triangles) and calculated using both measured values (red circles). Red circles in (A) and (B) are the same as those used in Figure 4. The broken lines and PBF also represent the same as in Figure 4.
