Table 12. Concentrations of total, inorganic, and organic carbon in sediments and rocks from Holes 897A, 897C, and 897D.

Notes: Concentrations of calcium carbonate have been estimated from the inorganic carbon values, assuming all of the inorganic carbon is present as CaCO₃. Concentrations of organic carbon have been estimated from the difference between total and inorganic carbon values. Atomic C/N and C/S ratios were calculated from concentrations of organic carbon, total nitrogen, and total sulfur, respectively.
