Abstract
Lofer cyclothems of the Upper Triassic Dachstein Limestone of the Julian Alps (northeastern Italy) are the focus of a new sedimentological-cyclostratigraphic study. A 112-cycle-long field section reveals that the meter-scale basic cycle shallows upward, from subtidal megalodont-bearing subfacies to intertidal laminites, capped by a paleosol subfacies. Time-series analysis of a correlative grayscale scan of a high-resolution field photograph shows that a 166-m-thick succession of Lofer cycles has time-frequency characteristics consistent with Earth's precession index, suggesting that the Lofer cycles were generated by eustatic sea-level oscillations that were forced by Milankovitch cycles.
