متن کاملOrganic carbon burial rate and the molybdenum proxy: Theoretical framework and application to Cenomanian-Turonian oceanic anoxic event 2
[1] In this study the controls on organic carbon burial and molybdenum accumulation in ancient strata are investigated through an integration of biogeochemical modeling and data analysis. Critical aspects of the study are employment of a biogeochemical model for organic matter degradation to explore the controls on pore water sulfide generation and authigenic molybdenum accumulation and use of ...

متن کاملMultiple Milankovitch Cycles in the Bridge Creek Limestone (cenomanian-turonian), Western Interior Basin
Spectral analyses of complementary lithologic and paleoecologic data sets from the Cenomanian-Turonian Bridge Creek Limestone are used to test for Milankovitch periodicities. Because the analyses quantitatively assess variance in the data sets through the study interval, they also offer a new method for evaluating relationships between different components of the depositional system. The analys...
