Of ancient marine tidal deposits without other lines of evidence supporting a marine depositionalĮnvironment may therefore require reevaluation. A key implication of this is that theĬlassic “tidal” sedimentary structures recognized in ancient rock successions should not automaticallyīe attributed to astronomical or marine tidal currents, since similar structures canīe generated by meteorological processes in continental environments. Have been documented together in a continental setting. This is the fi rst time such sedimentary features Tides generated by daily changes in wind direction and velocity, along with weekly to monthlyĭischarge variations in the feeder river system. We attribute the formation of these features in Lake Eyre to meteorological Setting, thus challenging the current paradigm that these structures are indicative of marine

Here, we detail similar sedimentary featuresįrom shoreline deposits of Lake Eyre, Australia, a present-day, intracratonic playa lake Sedimentary structures formed by marine tidal processes are nowįrequently described in modern and ancient deposits. These features could be directly related to astronomical forcingīy the Sun and Moon. Studies of modern sediments from tide-dominated marine coastal environments in theġ970s and 1980s led to the recognition of what were suggested to be unique sedimentary featuresįormed by tidal currents.
