Title:

Reconnaissance bedrock geologic map for the northern Alaska Peninsula area, southwest Alaska, including the Dillingham, Iliamna, Lake Clark, Taylor Mountains and the western part of the Kenai and Seldovia 1:250,000-scale quadrangles

Description:

Abstract:: The northern Alaska Peninsula map area lies on the west side of Cook Inlet in southcentral Alaska and consists of parts of the Kenai and Seldovia 1:250,000 scale quadrangles that lie on the west side of Cook Inlet and also the Lake Clark, Iliamna, Taylor Mountains, and Dillingham 1:250,000 scale quadrangles to the west. The map area is a region of transition from the classic magmatic arc geology of the Alaska Peninsula to the accretionary geology of southcentral and southwest Alaska, and to the poorly understood, tectonically complex sedimentary basins of southwest Alaska.
This data set is a portion of a statewide geology database, which is being compiled by the U.S. Geological Survey's National Surveys and Analysis (NSA) project, whose goal is to compile geologic, geochemical, geophysical, and other data.
Purpose:: This data set represents part of a systematic effort to release geologic map data for the United States in a uniform manner. Geologic data in this series has been compiled from a wide variety of sources, published and unpublished, ranging from state and regional geologic maps to large- scale field mapping.

Data_Set_Credit:

This data set was prepared by Frederic H. Wilson (USGS), Solmaz Mohadjer (contractor), Keith A. Labay (contractor), and Nora Shew (USGS)

Native_Data_Set_Environment:

Data set was created using ESRI ARC/Info version 7.2.1 on a Unix platform

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: There were many types of source materials, of varying scale, used to compile this data set. Sources include previously published maps, unpublished mapping, air photo interpretation, and limited new field mapping. The dates of the mapping range from the present to the 1930's. Vector features were mostly digitized on a large digitizing tablet. Vector and polygon attributes were assigned based on the original source. The digital data has been 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, dike, etc.)

Completeness_Report:

The complete data set consists of 11 different GIS coverages, six geology coverages and 5 lineation coverages. There is also an associated relational database of geologic units. Each coverage has the extent of a 1:250,000 scale quadrangle. A graphic representation of the database and a report with complete geologic unit descriptions is provided in .pdf format.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: This data is presented for use at a nominal scale of 1:350,000, although some sources were from 1:250,000- and 1:63,360 scale mapping.

Lineage:

Process_Step:

Process_Description:

Linework for the geology compilation was hand digitized from material of various media and scale. The arcs and polygons were attributed. The spatial databases are provided in UTM projection and geographic coordinates. The native ARC/Info coverages have been exported to an interchange file format, .e00, and also converted to ArcView shape files.

Entity_and_Attribute_Information:

Detailed_Description:

Entity_Type:

Entity_Type_Label: polygons
Entity_Type_Definition:: Characteristics of the polygon features in the geology coverages are coded in the polygon attribute table. The table <cov>.pat includes the following items CLASS, NSACLASS, NSAMOD, QCLASS (not used), 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 9120. 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. Each NSACLASS matches with geologic unit labels in LABEL and has a minimum (MIN_AGE) and maximaum (MAX_AGE) range, given in million of years (my).

Supplemental attribute tables included with this data set, contain additional descriptive information of each geologic unit. A user may use items SOURCE and CLASS to retrieve information about the original units from which these generalized units were formed.

NOTE: Because of the limitations of common GIS fonts, the letters "C", "Mz", "Pz", "Tr", and "Z" are substituted for the standard symbols for "Cambrian", "Mesozoic", "Paleozoic", "Triassic", and "Proterozoic."

Attribute_Label: SOURCE

Attribute_Definition:

SOURCE is a character (6 8 C) item found in both the polygon and arc attribute tables. The values are abbreviated codes representing the original source reference for the polygon or arc feature. The format for SOURCE is XX###, where XX is a two letter code for the 1:250,000 scale quadrangle and ### is a three digit number (with leading zeros). All source codes with '001' are unspecified sources for water and ice features, often paper topographic maps, and DRG or DLG files.

Detailed_Description:

Entity_Type:

Entity_Type_Label: arcs
Entity_Type_Definition:: Characteristics of the arc features in the geology and lineation coverages are coded in the arc attribute table. Table <cov>.aat includes the following items: ARC-CODE, ARC-PARA1, and SOURCE. For explanation of SOURCE, see 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 0 to 99. Values match one-for-one with geologic features (such as stratigraphic boundary, fault, etc.) Some ARC-CODE values have additional modifiers in item ARC-PARA1.
