These lineaments are thought to reflect structures in the crust that may be related to earthquake generation or control of earthquake location. The broad Paducah gravity lineament trends southeast across the SW corner of the map area. Hildenbrand and others (1996) have interpreted that the lineament represents numerous upper-crustal mafic intrustions. Within and west of the map area, small earthquakes are aligned with the NE edge of the lineament and their abundance decreases abruptly NE across the edge. The Commerce geophysical lineament trends NE across the map area. Langenheim and Hildenbrand (1997) attribute the lineament to a mafic dike swarm of unknown age. Topographic lineaments, Quaternary offsets on mapped faults, igneous intrusions, and a few earthquakes align along the lineament. The south-central magnetic lineament trends NW across the center of the map area and extends far beyond the map area in both directions. Hildenbrand and others (1996) interpret the lineament as a 40 km wide zone of high susceptibility intrusions of intermediate composition and probable Pc age. Heigold and Kolata (1993)suggest that the lineament may represent Precambrian Proterozoic terrane boundary. Seismicity south of the lineament (Reelfoot Rift) is greater than seismicity north of the boundary (Wabash Valley), but this boundary is located further to the south and trends more northerly than the south- central magnetic lineament. Present evidence implies that this lineament is the least likely to be causally related to modern seismicity. 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 ) Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1995 Ending_Date: 1997 Currentness_Reference: cover contains locations of all published lineaments Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -89 East_Bounding_Coordinate: -87 North_Bounding_Coordinate: 39 South_Bounding_Coordinate: 36.5 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: gravity lineament Theme_Keyword: magnetic lineament 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 Data_Set_Credit: Hildenbrand 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, Diehl, S.F., Drahovzal, J.A., Bear, G.W., and Sargent, M.L.
