Haxel 2005 Version 1.0 vector digital data U.S. Geological Survey Open-File Report 2005-1305 Reston, Virginia, USA U.S. Geological Survey Original source of this data was the Arizona Geological Survey. http://pubs.usgs.gov/of/2005/1305/ These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format. Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units. The data is provided in decimal degrees and in Lambert Conformal Conic projection. The data is provided in both coverage and shapefile format, and includes supplemental attribute tables. No attempt was made to reconcile differences in mapping across state boundaries. 2005 publication date Complete None planned -115.692550 -108.394050 37.506613 30.723759 none geology lithology geologic age maps none USA Arizona No warranty, expressed or implied, is made regarding the accuracy or utility of this data for general or scientific purposes, nor shall the act of distribution constitute any such warranty.

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.0.0.535 Map unit designations follow original compilation faithfully. Additional information about age and lithology was obtained from the paper map legend and geologic literature. All internal polygons were checked for closure. Overshoots and undershoots have been deleted or corrected as appropriate. The dataset contains all the map units and faults that were portrayed on the original printed map. Bodies of water are classified as water, and geologic units underlying them are not portrayed. The geologic map was digitized from compilations ranging in scale from 1:100,000 to 1:1,000,000, and is an accurate representation of the source maps. It is intended to be used at scales equal to or smaller than 1:500,000. Display at significantly larger scales may produce error in location of contacts or faults relative to features contained in other data sets. The state boundary arcs are based on the 1:100,000 scale USGS topographic map series digital line graphs. S.J. Richards 2001 DGM 17 Tucson, AZ Arizona Geological Survey A representation of Arizona Geological Survey Map 35 CD-ROM AGS DGM17 Bruce R. Johnson Unpublished Material vector digital data 100,000 online US001 Provided linework for state boundaries Dataset copied. 2003 Adjusted the perimeter of the coverage to match a reference dataset of state boundaries derived from 1:100,000 scale digital line graphs. This allows the map to be used together with adjoining state maps referenced to the same boundary data. Replaced a section of the state boundary that follows the Colorado River with a line from 1:100,000 scale digital line graph hydrographic files. The state and international boundaries have a source of US001 in the AAT. 2004 A polygon was relabeled Pz (from Ppa) to conform to the printed map (source in PAT = AZ901); A polygon was relabeled Jsv (from Jv) to conform to the printed map (source in PAT = AZ902); A polygon was relabeled Jv (from Jsv) to conform to the printed map (source in PAT = AZ903); A polygon was relabeled Jv (from Jsv) to conform to the printed map (source in PAT = AZ904). 2004 Nine arcs were changed from contacts to ARC-CODE = 30 (fault, sense of displacement unknown, location certain; source in AAT = AZ801). 2004 Twenty-one arcs were changed from contacts to ARC-CODE = 8 (internal contact, no line; source in AAT = AZ802). 2004 Fourteen arcs were changed from generic high-angle fault to ARC-CODE = 4 (normal fault, location certain; source in AAT = AZ804). 2004 One arc was changed from generic high-angle fault to ARC-CODE = 109 (detachment fault, location certain; source in AAT = AZ805). 2004 One arc was changed from thrust fault to ARC-CODE = 4 (normal fault, location certain; source in AAT = AZ806). 2004 Nineteen arcs were changed to ARC-CODE = 4 (normal fault, location certain; source in AAT = AZ808). These arcs also had their polarity flipped to conform to right-hand rule. 2004 One hundred fifty-two arcs had their polarity flipped to conform to the right-hand rule (source in AAT = AZ803) 2004 The appropriate arcs were recoded as state and international boundaries. 2005 To prepare a uniform AAT file, the following items were added: arc-code, arc-para1, and arc-para2. The last two are not used. Arc-code was populated, using the information in the original item, and inspection of the printed map. Then the original items in the AAT were deleted (OBJECTID, DATASETID, ACCURACY, TRACKINGID, TRACKINGDS, CONCEPTID, CONCEPTDS, CCONF, CARTOOBJID, CARTOOBJDS, LABEL, NAME). 2005 To prepare a uniform PAT file, the following items were added: ORIG_LABEL, SGMC_LABEL, UNIT_LINK, SOURCE, UNIT_AGE, ROCKTYPE1, and ROCKTYPE2. ORIG_LABEL was populated from the original item (PTYPE), SGMC_LABEL and UNIT_LINK were populated with information in the accompanying attribute table AZunits, UNIT_AGE was populated with information in the accompanying attribute table AZage, and ROCKTYPE1 and ROCKTYPE2 were populated with information in the accompanying attribute table AZlith. Then the original items in the PAT were deleted (OBJECTID, DATASETID, ACCURACY, TRACKINGID, TRACKINGDS, CONCEPTID, CONCEPTDS, CCONF, CARTOOBJID, CARTOOBJDS, MAPUNITID, MAPUNITDS, MCONF, LABEL). 2005 Metadata imported.
