It was compiled from many published and unpublished sources which were interpreted and correlated to create a consistent geologic map. This dataset is also a portion of a statewide geology database, which is being compiled by the U.S. Geological Survey's National Surveys and Analysis project (NSA), whose goal is to compile geologic, geochemical, geophysical, and other data. Purpose: This data set is a compilation of many sources to create a regional and correlated geologic history of the area of Wrangell-St. Elias National Park and Preserve. Supplemental_Information: Digital representation of geologic mapping facilitates the presentation and analysis of earth-science data. Digital maps may be displayed at any scale or projection, however the geologic data in this entire data set is presented for use at a nominal scale of 1:350,000. Individual data sets may contain data for use at larger scales.

Native_Data_Set_Environment: Data set was created using ESRI ARC/Info version 7 on a Unix platform. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The original source materials for this data set are from various scales (1:63,360 to 1:250,000), medium (digital, mylar, paper), and scope (bedrock, surficial, tectonic). All vector features were originally hand digitized on a large digitizing tablet or on screen. Vector and polygon attributes were assigned based on the original source. The digital data has been visually checked, and the geologic map has been technically reviewed and edited. Logical_Consistency_Report: Each geology coverage is a network coverage containing attributed arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults, stratigraphic contacts, and other linear features are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangling arcs may be present (faults, dikes, etc.) Completeness_Report: This dataset was used to create the geologic map portion of the Wrangell-St. Elias National Park and Preserve geologic map. Text files, graphics, and other files used to produce the publication are not included here. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Users of this digital data set should respect the intentions of the original mappers, compilers, and the limitations of a thematic map. This compilation was compiled from sources with scales ranging from 1:63,360 to 1:250,000, however this compilation is being published at 1:350,000 scale.

The table .pat includes the following items: CLASS, NSACLASS, NSAMOD, QCLASS, SOURCE, LABEL, MIN_AGE, and MAX_AGE Entity_Type_Definition_Source: This data set Attribute: Attribute_Label: NSACLASS Attribute_Definition: NSACLASS is a positive integer value (4 5 B) item in the polygon attribute table. Values range discontinuously from 98 to 7400. NSACLASS is a numeric code for the geologic unit. This data set represents a generalized map, thus it is possible that a geologic unit is made of multiple NSACLASS values. This specific map area includes more detailed Quaternary mapping, requiring some of the NSACLASS values to be subdivided. These geologic units are attributed in the .pat item QCLASS. Each NSACLASS or QCLASS matches with geologic unit labels in LABEL and has a minimum (MIN_AGE) and maximum age (MAX_AGE) range, given in million of years (my). Supplemental attribute tables included with this data set, contain addtional descriptive information of each geologic unit. A user may use items SOURCE and CLASS to retrieve information about the original units from which these generalize units were formed. Also, see the USGS publication, SIM 2877, for full descriptions of the geologic units within the Wrangell-Saint Elias National Park and Preserve area. For explanation of SOURCE, see metadata section 2.5 Lineage. NOTE: Because of the limitations of common GIS fonts, the letters "Mz", "Pz", "Tr", and "Pa" are substituted for the standard symbols for "Mesozoic", "Paleozoic", "Triassic", and "Pennsylvanian."

Detailed_Description: Entity_Type: Entity_Type_Label: arcs Entity_Type_Definition: Characteristics of the arc features in the geology coverages are coded in the arc attribute table. Table .aat includes the following items: ARC-CODE, ARC-PARA1, and SOURCE. For explanation of SOURCE, see metadata section 2.5 Lineage and/or attribute definitions for polygons. Entity_Type_Definition_Source: this data set Attribute: Attribute_Label: ARC-CODE Attribute_Definition: ARC-CODE is a positive integer value (3 3 I) item in the arc attribute table. Values range discontinuously from 1 to 99. Values match one-for-one with geologic features (such as stratigraphic boundary, fault, etc.). Some ARC-CODE features have additional modifiers in item ARC-PARA1.
