Lithologic Symbols
Chart showing basic lithologic symbols.
|
Basic lithologic symbols are provided as guidelines. Symbols similar to
these are generally acceptable for use as patterns both on sediment
distribution maps and in lithologic columnar sections, such as on core
description forms. Although the symbols shown are the most commonly used
symbols for each of the respective lithologies, the patterns must still
be explained separately in a key. As with most graphics, users should
also be mindful of the eventual publication scale when choosing line
weights.
