  • Trough Cross Stratification/Lamination

    14,998 views 6 years ago
    In this video, I describe variations in geometry in dune and ripple cross stratification/lamination due to non-linear bedform crests.

    David Rubin at the United States Geological Survey has posted numerous excellent animations of how bedform geometry influences cross stratification. They can be found at: http://walrus.wr.usgs.gov/s... I particularly like these two animations for showing the effects of linear vs sinuous ripples: http://walrus.wr.usgs.gov/s... and http://walrus.wr.usgs.gov/s...
