Separates for geology, surface faults, and cultural features were scanned and sent via email from U. S. Geological Survey, Reston, VA. The scanned data was converted to a ARC/INFO georeferenced cover. Our intent is to show the overall fault pattern, and to show the locations of the main exposed and near-surface faults for comparison to deep subsurface structures. We made little attempt to edit details of the digitized faults, beyond adding tic marks to indicate dip directions of a few normal faults. For details such as exact locations, fault dips, separations, and cross-cutting relations, users should consult the original geologic map and the more detailed maps from which it was compiled. Purpose: The data was generated to help in understanding the seismotectonic hazards in the vicinity of the lower Wabash Valley. This data complements similar data collected in the vicinity of New Madrid, MO (US Geological Survey Open-File Report 95-0574, available via ftp at ) Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -89 East_Bounding_Coordinate: -86.99998474 North_Bounding_Coordinate: 39 South_Bounding_Coordinate: 36.5 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: Kentucky faults Place: Place_Keyword_Thesaurus: None Place_Keyword: Wabash Valley Access_Constraints: none Use_Constraints: none Point_of_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Susan Rhea Contact_Organization: US Geological Survey Contact_Position: Geophysicist Contact_Address: Address_Type: mailing address Address: MS966, Box 25046, Federal Center City: Denver State_or_Province: CO Postal_Code: 80225 Country: USA Contact_Voice_Telephone: 303-273-8639 Contact_Facsimile_Telephone: 303-273-8600 Contact_Electronic_Mail_Address: rhea@usgs.gov Contact_Instructions: email is the best way to make contact Native_Data_Set_Environment: SunOS, 5.5.1, sun4u UNIX, ARC/INFO version 7.1.1 Cross_Reference: Citation_Information: Originator: Wheeler, R.L., Rhea, Susan, and Diehl, S.F., Drahovzal, J.A., Bear, G.W., and Sargent, M.L.

Logical_Consistency_Report: Chain-node topology present. Completeness_Report: all faults included on the Geologic Map of Kentucky within the map area are represented in this cover Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Original scale 1:500,000. The scanned images were not georeferenced, and an unknown amount of error was introduced during the georeferencing process. No tests performed. Accuracy of locations on the Geologic Map of Kentucky is unknown. The relative accuracy in this representation is the same as on that source map. Absolute locations are within several km, although this is estimated. Faults were compared to those on 1:250,000 scale Paducah Quadrangle Geologic Map and were adjusted to connect where it appeared they should.

The covers were not georeferenced and had to be 'rubber-sheeted'. This involved TRANSFORMing the cover from page units (inches) to map units (meters) in an Albers Equal Area projection. Cultural features and latitude/longitude intersections were identified on the cultural features cover and on previously georeferenced base covers. Links between the two covers were created and the cultural features cover was ADJUSTed and compared to the base cover. Several iterations of creating links and ADJUSTing were required to get a good match. The links were then copied from the cultural features cover into the fault cover and used to ADJUST the faults. The adjusted cover was clipped to the map area. The resulting fault cover overlapped some of the more accurate data in the Paducah cover (padflt) and the less accurate data in the Illinois Basin Consortium cover (ibcflt). This cover's boundary was used to erase overlapping faults in the IBC cover. This cover was erased by the Paducah cover's boundary. At the boundary between the Paducah cover and Kentucky cover, misalignments between faults were visible. These errors were assumed to be in the Kentucky cover and it was adjusted again to eliminate misalignments. Revisions: Data not explicitly changed, although location inaccuracies introduced or corrected by transform and adjust procedures is unknown.
