Abstract
delta C-13 values of numerous limestone samples from Katian (Upper Ordovician) successions in Oklahoma and the Upper Mississippi Valley document the presence of at least three of the four positive excursions that have been recognized in the lower-middle Katian interval in the Cincinnati region in Ohio. Kentucky, and Indiana. A comparison with Estonia reveals that five out of the six positive excursions now recorded through the Katian succession in the Cincinnati region are present in the coeval stratigraphic intervals in Estonia, which suggests that these represent global perturbations in the carbon cycle A study of the relations between flooding events and delta C-13 excursions shows that only some of the excursions occur in transgressive...
