Reconstruction of Depositional Environments in the Pennsylvanian Vanport Basin by Carbon Isotope Ratios
J. N. Weber, R. E. Bergenback, E. G. Williams, M. L. Keith [email protected] State University, University Park, Pennsylvania
Detailed variations of the carbon isotope ratio have been determined in the limestones of a Pennsylvanian marine basin and the bordering transitional marine zones. It is shown that there is a general inverse relationship between average carbon-13 content and proximity to the ancient shorelines and deltaic distributaries.
