Presentation Transcript

  1. Individual deposits from local regions also exhibit breaks in the cumulative frequency curve According to Visher (1969): Breaks from: 1) Each sample has multiple populations based on transport history

  2. Cumulative Frequency plots of sediment from some different depositional environments Modern Beach Dune Turbidite

  3. Cumulative Frequency plots of sediment from some different depositional environments Till

  4. Skewness – Measures asymmetry of the curve. Reflects sorting in the tails of a sediment sample Dune Sand Where would Dune Sand plot on the graph? Why?

  5. C-M/LM Diagrams Plot the 50th percentile (median) against the coarsest or finest percentile

  6. II. GRAINSHAPE • Form – Gross overall configuration of grain. • Roundness – a measure of the angularity of grains (sharpness of corners). • Surface Texture – small scale, micro-relief of grain surface. Pits, scratches, and ridges/
