Notes: FeP was calculated from SP measurements considering the stoichiometric composition of pyrite. Corresponding main, minor, and trace elements are found in Hetzel et al. (this volume). TOC = total organic carbon, TIC = total inorganic carbon, FeT = total iron, FeP = pyrite iron, FeHR = highly reactive iron, ST = total sulfur, SP = pyrite sulfur, SORG = organic matter (essentially kerogen)-bound organic sulfur.
