This compilation was done as part of the U.S. Geological Survey's Alaska Mineral Resource Assessment project (AMRAP), whose goal was to create and assemble geologic, geochemical, geophysical, and other data in order to perform mineral resource assessments on a quadrangle, regional, or statewide basis. The digital data here was created to assist in the compilation of a regional mineral resource assessment of the Alaska Peninsula.
The linework was captured by hand digitizing from hand-drawn 1:63,360- and 1:250,000-scale mylar and paper maps that were in very good condition. Vector and polygon attributes were obtained from field maps and compilations. The digital data has been visually checked and the geologic map has undergone multiple technical reviews by J.R. Riehle, J.C. Moore, and C. Molenaar.
Users of this digital geologic map should respect the intentions of the original mappers and the limitations of the map. This geologic map compilation is intended to be used at a scale of 1:250,000; it is not intended to be used at a more detailed scale.
The complete digital OFR contains all files needed to create the map sheet titled "Geologic map of the Alaska Peninsula, southwest Alaska."
The geology data sets (mkgeol, uggeol, cggeol, pmgeol, cbgeol, and krc45) are network coverages containing arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults and stratigraphic contacts 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.)
The fold axes data sets (mkfld-alb, ugfld-alb, cgfld-alb, pmfld-alb, and cbfod-alb) are arc coverages. Dangling arcs are present. Folds mapped showing plunge were digitized in the direction of the plunge.
