Polygon attribute table for the geology coverage. The attributes address the identification, symbolization, age, lithology and description of the rock units.

Label Definition
MAP_CODE Symbol for the different units on the map. (character, width 16)
general_symbol A general symbol for the units (a little less detailed than the map symbols, code of width 16)
Map_unit Type of rocks (descriptive text of width 125))
age Geologic age of the map units (descriptive text of width 40))
groupings terranes (grouping of the units into common terranes) (descriptive text of width 80)
descriptio Specific lithologic description of the units. (descriptive text of width 200)
geo_prov geologic provinces (descriptive text of width 25)
lithology units are classified by lithology based on Bruce Johnson's classification scheme. (descriptive text of width 33)
