Figure F20. Calcium carbonate, total organic carbon, C/N ratios, hydrogen index values, total sulfur, and C/S ratios at Site 1192. The dashed line at HI = 150 marks the approximate boundary between terrigenous (<150) and marine organic matter, and the dashed line at C/N = 25 approximates the terrigenous organic matter field (~25-35).
