Organic carbon burial rate and the molybdenum proxy: Theoretical framework and application to Cenomanian-Turonian oceanic anoxic event 2

摘要: [1] In this study the controls on organic carbon burial and molybdenum accumulation in ancient strata are investigated through an integration of biogeochemical modeling data analysis. Critical aspects employment a model for matter degradation to explore pore water sulfide generation authigenic use rate Mo, OC, CaCO3, Fe, Ti reconstruct remineralization processes. The results form conceptual framework interpretation primary production estimates geochemical fluxes (calculated basis high-resolution orbital timescale) Cenomanian-Turonian (C-T) oceanic anoxic event 2 interval Western Interior basin. suggest that strong correlation between source rock development intervals transgression geologic record (such as C-T) could reflect confluence processes within sediments obviates need large-magnitude changes levels or oceanographic conditions prolonged periods stable column stratification).
