JOINED & RELATED TABLES: Lithologic Unit Detail

revised: 29-Feb-2012

Table Name: Lithology

This table is used to link detailed information about mapped lithostratigraphic and lithodemic geologic units to Lith_poly and Subcrop_poly. The one-to-many relationship is based on the GeolID field. The attributes within this table apply to all areas within a given map extent with matching GeoIDs.
