Plotting routine for Gravel, Sand, Mud

| Watch this File

File Information

This script makes a ternary diagram for sand, mud and gravel, assuming
that mud=(silt+clay). The plot is based on Schlee (1973), a modification
on the Shepard (1954) classification system. The Schlee modification
utilizes the same ternary plotting style, but adjusts to include the
larger sized portion of sediments.

This script is a modification of the TERNPLOT script by Carl Sandrock (20020827),
and the 'Shepard.m' written by William (Bill) Waite.
This modification simply adds the labels required for the Schlee diagram.

NOTE: The plotted result may be screen dependent. If this happens,
simply use the magnify tool to zoom in on the plot.
