Eccentricity Control on Fluvial Sedimentation in the Tropics During the Middle-Late Pennsylvanian Icehouse (~306-314 Ma, Upper Silesian Basin)

This study examines the Cracow Sandstone Series (CS), which provides a snapshot of the Middle to Late Pennsylvanian (~306-314 Ma) fluvial sedimentation in the eastern equatorial Pangea (Upper Silesian Basin, ~2°N paleolatitude). Spectral estimates of borehole lithological data suggest predominant ~100-kyr eccentricity pacing of coal-bearing fluvial cycles and persistence of this pattern across the onset of Late Pennsylvanian aridification.
