Description: Lines (e.g., cross-section lines) that have no real-world physical existence, such that LocationConfidenceMeters, ExistenceConfidence, and IdentityConfidence attributes are meaningless, and that are never shown as concealed beneath a covering unit. In the original file geodatabase, this dataset is found within the GeologicMap feature dataset.
Description: Lines that represent dikes, coal seams, ash beds, fold hinge-surface traces, isograds, and other linear features. All have these properties: (A) They do not participate in map-unit topology. (B) They correspond to features that exist within the Earth and may be concealed beneath younger, covering, material. (C) They are located with an accuracy that likely can be estimated. In the original file geodatabase, this dataset is found within the GeologicMap feature dataset.
Description: Contacts between map units, faults that bound map units, and associated dangling faults. Includes concealed faults and contacts, waterlines, snowfield and glacier boundaries, and map boundary. In the original file geodatabase, this dataset is found within the GeologicMap feature dataset.
Description: Overlay polygons or other non-geologic polygons that represent overlying earth material, reclaimed areas, or otherwise non-geologic material mapped within the quadrangle.
Description: Polygons that record distribution of map units (including water, snowfields, glaciers, and unmapped area) on the particular map horizon. In the original file geodatabase, this dataset is found within the GeologicMap feature dataset.
Description: Non-spatial table of sources of all spatial features, sources of some attributes of spatial features, and sources of some attributes of non-spatial table entries.
Description: Non-spatial table that captures content of the Description of Map Units (or equivalent List of Map Units and associated pamphlet text) included in a traditional paper geologic map. Has an internal hierarchy expressed by attribute HierarchyKey.
Description: Non-spatial table that, for certain fields (including all Type fields, Confidence fields, and GeneralLithology), lists the terms that populate these fields, term definitions, and sources for definitions.
Description: Properties of the map report as a whole. May include title, authorship, scale, geologic mapping credit, editing credit, cartography credit, date of approval, local magnetic declination, publication series and number, and base map information.
