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.
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 Geologic data in this series has been compiled from a wide variety of sources, published and unpublished, ranging from state and regional geologic maps to large scale field mapping.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_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 Sources include previously published maps, unpublished mapping, air photo interpretation, and limited new field mapping.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:
The geologic data consists of attributed arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults, stratigraphic contacts, dikes, lineations 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 (fault, dike, lineation, etc.).
Completeness_Report:
The data set NAP_geol.gdb consists of arc and polygon features depicting the geology of the northern Alaska Peninsula. The geologic units are described in the Description of Map Units (DMU) found in the accompanying pamphlet. There is also an associated relational database of geologic units.

Attribute_Label: NSAMOD
Attribute_Definition:
Indicates if a geologic unit is altered, contact metamorphosed, or has a queried unit assignment. Some maps show contact metamorphosed areas as separate units; these units are assigned a NSACLASS for the appropriate protolith and have 'HFS' selected as NSAMOD value. If only a few polygons of a geologic unit are altered or contact metamorphosed, then the NSAMOD value is set for those polygons only. When NSAMOD has the value 'Q'or 'HFS, Q' the geologic unit is 'queried' and the symbol '?' is appended to the value in LABEL and LABEL2.

Attribute_Definition:

Attribute:
Attribute_Label: LINEID
Attribute_Definition:
LINEID provides additional attributes for some faults and glacial moraines. For faults, LINEID identifies the fault system the feature belongs to. For moraines, LINEID identifies the moraine or glacial limit. LINEID is an 8 character alpha-numeric code following this naming convention. The first letter is 'f' if the feature is a fault, or 'm' if a moraine. The second and third characters are alpha abbreviations for the fault system, region, or glaciation. These abbreviations are defined below. The final 4 numbers in LINEID are identifiers which further subdivide the line's description. Field LINEID is a key field for linking to field LINEID in table LINEID.
