Geological Survey Online_Linkage: http://pubs.usgs.gov/imap/i-2645-a/ Description: Abstract: The geologic map of the central Marysvale volcanic field, southwestern Utah, shows the geology at 1:100,000 scale of the heart of one of the largest Cenozoic volcanic fields in the Western United States. The map shows the area of 38 degrees 15' to 38 degrees 42'30" N., and 112 degrees to 112 degrees 37'30" W. The Marysvale field occurs mostly in the High Plateaus, a subprovince of the Colorado Plateau and structurally a transition zone between the complexly deformed Great Basin to the west and the stable, little-deformed main part of the Colorado Plateau to the east. The western part of the field is in the Great Basin proper. The volcanic rocks and their source intrusions in the volcanic field range in age from about 31 Ma (Oligocene) to about 0.5 Ma (Pleistocene). These rocks overlie sedimentary rocks exposed in the mapped area that range in age from Ordovician to early Cenozoic. The area has been deformed by thrust faults and folds formed during the late Mesozoic to early Cenozoic Sevier deformational event, and later by mostly normal faults and folds of the Miocene to Quaternary basin-range episode. The map revises and updates knowledge gained during a long-term U.S. Geological Survey investigation of the volcanic field, done in part because of its extensive history of mining. The investigation also was done to provide framework geologic knowledge suitable for defining geologic and hydrologic hazards, for locating hydrologic and mineral resources, and for an understanding of geologic processes in the area. A previous geologic map (Cunningham and others, 1983, U.S. Geological Survey Miscellaneous Investigations Series I-1430-A) covered the same area as this map but was published at 1:50,000 scale and is obsolete due to new data. This new geologic map of the central Marysvale field, here published as U.S. Geological Survey Geologic Investigations Series I-2645-A, is accompanied by gravity and aeromagnetic maps of the same area and the same scale (Campbell and others, 1999, U.S. Geological Survey Geologic Investigations Series I-2645-B). Purpose: This database was developed to improve upon previous mapping in the central Marysvale volcanic field and compile older mapping at a consistent scale. This area is an important mining district, and a regional understanding of the geology and mineral deposits will assist in understanding genesis of deposits and in exploration for new deposits. The area is also an important part of the transition zone between the Colorado Plateau to the east and the Great Basin to the west. This tectonically significant province may hold keys to the style and mechanisms of continent-scale deformation in the Western United States.

Frequency tests were run on the lines and polygon labels to ensure that no arcs or polygons are unlabeled. The attributes have been checked by the authors for agreement with field maps, annotated aerial photographs, and preliminary drafted versions of the map. The attribute data in the data set should be taken as an accurate representation of the authors' geologic interpretations. Logical_Consistency_Report: The entire study area was mapped both by photo-interpretation and by extensive field work at 1:50,000- and 1:24,000-scale over the course of several decades. The entire map area was mapped at the same level of detail. All linework was digitized at 1:24,000-scale, except for parts of the northwestern corner of the map, which were digitized at 1:50,000-scale, and edits were made, adjoining quads edge-matched and snapped, and attributes were added using GSMCAD (Williams, 1996). All lines were visually inspected by the authors for proper intersections, repetition, overshoots, undershoots, and overall logical consistency. The geologic features in the map area are all described, in the view of the authors, at a consistent scale of 1:100,000. All coverages were cleaned and built in ARC/INFO (version 7.1.2) to ensure a logical consistency that is topologically clean. Completeness_Report: This dataset includes only the coverages pertaining to the geologic map. Supplemental text and illustrations on the printed map (correlation chart, explanation of map symbols, cross-section) are not included. This map was produced to be used at 1:100,000-scale. Any geologic features too small to be shown at this scale have been omitted or generalized if they are of significant importance. The smallest objects are approximately 40 meters on a side. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The estimated horizontal positional accuracy of the data is 15 meters. Mapping at 1:24,000-scale (1:50,000-scale in the northwest corner of the map area) was generalized to 1:100,000-scale. All linework was digitized at 1:24,000-scale by using a CalComp digitizing table (model 95482) having an error of +/-0.001 inches (< 1 meter at map scale). This database was produced to be used at 1:100,000-scale and any problems arising from use at other scales are not the responsibilities of the authors. No vertical data are included in the database.
