Preliminary Integrated Geologic Map Databases for the United States Central States: Montana, Wyoming, Colorado, New Mexico, Kansas, Oklahoma, Texas, Missouri, Arkansas, and Louisiana, - The State of New Mexico
This open-file report presents the results of the USGS Mineral Resources Program activity to compile a national-scale geologic map database to support national and regional level projects, including mineral resource and geo- environmental assessments. The only comprehensive sources of regional- and national-scale geologic maps are state geologic maps with scales ranging from 1:100,000 to 1:1,000,000. Digital versions of these state maps form the core of what is presented here. Because no adequate geologic map exists for the state of Alaska, it is being compiled in regional blocks that also form part of this national database. It is expected that this series will completed by approximately the end of 2007. These maps and databases are being released in blocks of states or, in the case of Alaska, as compiled blocks of 1:250,000-scale quadrangles as chapters in this series. For Alaska, formal maps as well as databases are being published here, whereas for the conterminous U.S. only state databases and preview graphics are presented, because published maps for most states already exist. For Alaska these regional compilations will form the base for compiling a new geologic map of the state. As documented in Chapter A, standards for the conterminous U.S. are somewhat different than those for Alaska and Hawaii.
This database consists of five major Arc/Info GIS datasets for each state; - one: geologic map with formations, - two: faults (where present), - three: dikes (where present), - four: miscellaneous line features (where present), - five: miscellaneous point features (where present).

Why was the data set created?

A primary goal of this work is to develop geologic map datasets with standardized structure and attribution. The database design and standards are documented in Chapter A of this series. The intent is that contiguous databases can be merged seamlessly and without any additional effort. In addition to a common database structure, the conterminous U.S. state databases (the contiguous 48 states) have been fitted to a set of standard state boundaries so that, when states are merged, they match without slivers or overlap. No attempt has been made to reconcile differences in mapping across state boundaries.

How was the data set created?

  2. How were the data generated, processed, and modified?
    Date: 2003 (process 1 of 6)
    The purpose of this standardization is to allow all SGMC covers to be seamlessly joined without any additional effort to form regional or national level digital maps. Note that for Alaska, the state is being compiled as blocks of 1:250k quadrangles that will ultimately be used to compile a new state map. Douglas Stoeser and Ric Wilson are co-coordinators for the overall SGMC effort, with Stoeser coordinating work on the mainland states and Wilson coordinating work for Alaska and Hawaii.
    Date: 16-Dec-2003 (process 2 of 6)
    G.N. Green obtained the digital geologic map of New Mexico from the website: Re-projected the coverage into the following:

    projection: Lambert Conformal Conic units: meters datum: NAD27 standard parallel 1: 33 0 0.000 standard parallel 2: 45 0 0.000 central meridian: -100 0 0.000 reference latitude: 0 0 0.000 false easting: 0.000 false northing: 0.000

    All attributes were deleted except NAME.

    (Note: Attributes associated with the generation of the coverages were not deleted. PAT - shape, area, perimeter, coverage#, and coverage-id AAT - shape, fnode#, tnode#, lnode#, rnode#, length, coverage#, and coverage-id)

    The values from NAME where then calculated into a new field called orig_label.
    Date: 22-Dec-2003 (process 3 of 6)
    The following attributes were exported from Filemaker as a comma delimited file

    map_symbol1 map_symbol2 unit_link reference_id unit_age rocktype1 rocktype2

    The attributes were then loaded into INFO with the following structures:

    item name: orig_label width: 12 output: 12 type: c

    item name: sgmc_label width: 16 output: 16 type: c

    item name: unit_link width: 18 output: 18 type: c

    item name: source width: 6 output: 8 type: c

    item name: unit_age width: 60 output: 60 type: c

    item name: rocktype1 width: 40 output: 40 type: c

    item name: rocktype2 width: 40 output: 40 type: c
    Date: 08-Sep-2010 (process 4 of 6)
    Once the .csv was loaded, it was joined in Arc/Info with the joinitem command. orig_label as the related item.
    Date: 02-Jan-2004 (process 5 of 6)
    Once the .pat file was correct, the .aat file was addressed. The following items were added to the table:

    item name: arc-code width: 3 output: 3 type: i

    item name: arc-para1 width: 3 output: 3 type: i

    item name: arc-para2 width: 3 output: 3 type: i

    item name: source width: 6 output: 8 type: c

    Date: 05-Jan-2004 (process 6 of 6)
    Arc-code was populated using the digital map source to tag the lines using the AAT line type data dictionary. Arc-para1 was populated when additional information was available such as upthrown side of a fault or angle of thrusting on a fault. Arc-para2 is a scratch field that is used mostly in Alaska. Source was populated with code that designates the source used for the linework; typically the paper map.
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The values of the attributes ROCKTYPE1 and ROCKTYPE2 were assigned based on the information in the legends of the source maps (most of which are paper). The definitions of these values are described in the draft document Geologic Map Classification version 6.1 (Johnson and others); available at the following website: )
  2. How accurate are the geographic locations?
    The geologic map was digitized from compilations ranging in scale from 1:1,000,000 to 1:100,000 and is an accurate representation of the source maps. It is intended to be used at scales ranging from 1:1,000,000 to 1:500,000. Display at significantly larger scales may produce small errors in locations of contacts or faults relative to features contained in other data sets. Accuracy of New Mexico state boundary and those arcs intersecting it: The accuracy of the state boundary arcs is based on the 1:100000 scale original data used to produce this boundary. (Johnson, Bruce R. and Leveritch, Beth, 1998, 1:100,000 Scale State Boundaries of the Conterminous United States: U.S. Geological Survey, unpublished (see metadata file: st100kmeta.txt, Chapter A)) Those internal arcs intersecting the state boundary were extended or shortened as needed to complete polygons, possibly creating a small amount of error.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Bodies of water are classified as water, and the geologic units underlying them are not included in this coverage.
  5. How consistent are the relationships among the observations, including topology?
    All internal polygons were checked for closure with vendor software and on hard copy plots. Overshoots and undershoots have been deleted or corrected as appropriate.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
