Early diagenetic repartitioning of carbon, sulfur, iron, and               manganese in poorly oxygenated to anoxic marine deposits will be                studied using new geochemical and stable isotopic data on the                   Miocene Monterey Formation and the mid-Cretaceous Greenhorn                     Formation.  Our objectives will be 1) to interpret interrela-                   tionships in the Corg-S-Fe-Mn system in terms of depositional and               early diagenetic conditions and 2) to reconstruct the pathways                  for transfer of sulfur from dissolved and solid inorganic-sulfur                species to organic-sulfur compounds in bitumen and kerogen.                     Organic and inorganic sulfur species will be isolated using a                   step-wise procedure that will yield seven sulfur fractions                      (sulphate, elemental, bitumen, acid-volatile, disulfide, barite,                and kerogen).  Depth and timing of pyrite formation relative to                 incorporation of sulfur into organic matter will be inferred from               the isotopic compositions of the various sulfur fractions in                    conjunction with the distribution of iron and manganese.  The                   Monterey and Greenhorn both contain interbedded laminated and                   bioturbated lithofacies that will enable us to sample a wide                    range of paleoenvironmental and early diagenetic settings.                      Integration of organic and inorganic sulfur data with manganese                 and iron data will provide a new basis for interpreting ancient                 poorly oxygenated to anoxic basins.  The geological units                       selected for this study will permit comparison of sedimentary                   strata in modern and Miocene coastal upwellings and in modern                   oceanic and Cretaceous epicontinental settings.
