| # 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
