Profile Plot Track Legends

The following symbols are created by using a text mask string array that is parsed and plotted on the profile plot tracks. The Lithology and the Rock Texture symbols are each 5 X 10 pixels, the Rock Texture Composition, Rock Porosity, Sedimentary Structure and Fossil Symbols are each 10 X 10 pixels. I used a number of references as guides to creating the symbols, the symbols are not exact reproductions of the symbols in the references just a facsimile.

Lithology Symbols1 Standard list of symbols and background colors for rock types.
Rock Texture Symbols2 The Rock Texture uses the Udden-Wentworth grain-size classification scheme for Siliclastic Rocks and the Dunham's Classification Scheme for the carbonate rocks. The Rock Texture composition uses Folks (1980) & R.H. Dott, Jr.(1964).
Rock Porosity Symbols1 The Rock Porosity uses the Choquette and Pray Classification system.
Sedimentary Structure Symbols1 The Sedimentary Structures starts from the Shell Document and adds a number of modification to group the different symbols.
Fossil Symbols4 The Fossil Symbols are facsimile of the standard fossil symbols by the Federal Geographic Data Committee.
Munsell Color Chart3 Uses the Universal Color Language, Level 3 Color Names by the ISCC & NBS. "The ISCC-NBS Method identifies 267 blocks of colors. Each block is given a color name devised using a set of adjectives and suffixes. Each color block defines a range of colors--not a single color--that have the same name. This range of color in each block is an acknowledged disadvantage, but it is pointed out (COLOR, p. 4) that a set of 267 color names is analogous to calendar dates for chronological events. This method is suitable for "a variety of scientific and industrial applications" (COLOR, p. A-13). The UCL at levels above 3 defines finer divisions of colors with no names, rising to approximately five million divisions in UCL Level 6. COLOR also lists color names from various sources for each UCL Level 3 color block (pp. 37-82) and a Dictionary of Color Names which lists thousands of color names and their corresponding UCL Level 3 block(s) (pp. 85-158)."3
