IODP Proceedings, Volume 335 Site 1256, Table T11. Thermal conductivity measurements on Section 335-1256D-235R-1 (Piece 1). N = number of measurements. Rotation = rotating angle of measurement, Across core = moving probe across the core from the edge to the center, Down core = moving probe vertically down the core. This table is available in ASCII and in Microsoft Excel format (see 103_T11.XLS in 103 in TABLES in “Supplementary material”).
