Professor Husinec publishes article on record of oceanic anoxia in shallow-marine carbonates
A new paper by Dr. Antun Husinec and Dr. Fred Read (Virginia Tech) in Elsevier’s Sedimentary Geology discusses how major stable carbon-isotope excursions, typically associated with deep-water oceanic anoxic events, are manifested in the shallow-marine carbonate platform sedimentary succession. It also provides one of the few documented cases of how astronomical forcing of carbonate platforms and carbon-isotope signal, are related. Given the susceptibility of platform facies to both early meteoric and later diagenesis, it also evaluates the effects of early meteoric vs later burial diagenesis on the preservation of the stable carbon-isotope signal. The paper provides several novel aspects to the integrated study of cyclostratigraphy, carbon-isotope chemostratigraphy and astronomical forcing of carbonate platforms.
