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.

purpose:
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.

Additional information on resource:
The orginal 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).

name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
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 Arkansas 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.

evaluation Method Description
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: http://geology.usgs.gov/dm)
