Publication_Date: 2010 Title: Preliminary bedrock geologic map of the Seward Peninsula, Alaska, and accompanying conodont data Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: U.S. Geological Survey Open-File Report Issue_Identification: OFR 2009-1254 Description: Abstract: Most of Seward Peninsula is underlain by rocks that were part of a Late Proterozoic to early Paleozoic continental margin; remnants of that margin are also present in the Brooks Range. The extensive high-pressure metamorphic rocks exposed in central Seward Peninsula (Nome Complex), the southern Brooks Range, and the Ruby geanticline are thought to record subduction of that continental margin during the Jurassic. Rolling, tundra-covered hills cover most of the Seward Peninsula; trees and shrubs are present only in limited areas in the southern and eastern parts of the Peninsula. An extensive, unvegetated lava field occupies a central area and large areas in northernmost and easternmost Seward Peninsula. The York Mountains of western Seward Peninsula and hills adjacent to them on the east are underlain by bare, unvegetated carbonate rocks. Four glacially carved mountain ranges, the York, Kigluaik, Bendeleben, and Darby Mountains, reach heights of 1,000-1,300 m. Broad lowlands underlie large areas in central and northern Seward Peninsula. This geologic map is a compilation of published and unpublished geologic mapping and information derived from other published and unpublished sources. Published geologic maps at scales of 1:250,000, 1:63,360, and 1:50,000 were major sources and range in publication date from 1972 to 2005. More detailed studies, including theses, papers, and unpublished mapping, represent work done between 1980 and 2008. 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 Geologic data in this series has been compiled from a wide variety of sources, published and unpublished, ranging from state and regional geologic maps to large- scale field mapping.

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, and air photo interpretation. The dates of the mapping range from the present to 1970's. Vector features were mostly heads up digitized from a scanned image. 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 13 different GIS coverages, nine geology coverages and four dike coverages. There is also an associated relational database of geologic units. Each coverage has the extent of all or part 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 1:500,000, although some sources were from 1:250,000, 1:63,360, or 1:50,000 scale mapping. Lineage: Process_Step: Process_Description: Line work 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, and also converted to shape files.
