The lines represent locations of magnetic highs that they interpreted as dikes. Modeling indicates the dikes are vertical, extend to within 200 m of the surface, and have the magnetic properties of mafic or ultramafic rock. Some of the interpreted dikes coincide with the easternmost Early Permian, mica peridotite and perhaps lamprophyre dikes that Nelson mapped (these are in cover lampdike.) Hildenbrand and Ravat concluded that the interpreted dikes are also probably Early Permian ultramafic intrusions. 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 at http://pubs.usgs.gov/of/1995/0574/ Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1996 Ending_Date: 1996 Currentness_Reference: Hildenbrand publication date Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -88.42851257 East_Bounding_Coordinate: -87.9046402 North_Bounding_Coordinate: 38.00849915 South_Bounding_Coordinate: 37.35390854 Keywords: Theme: Theme_Keyword_Thesaurus: USGS Thesaurus Theme_Keyword: geology Theme_Keyword: igneous rocks Theme_Keyword: geologic structure Theme_Keyword: geospatial datasets Theme: Theme_Keyword_Thesaurus: none Theme_Keyword: magnetic basement Place: Place_Keyword_Thesaurus: none Place_Keyword: Wabash Valley Theme: Theme_Keyword_Thesaurus: National Geologic Map Database Catalog themes, augmented Theme_Keyword: 1100 - Geology Theme_Keyword: 1101 - General Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Categories Theme_Keyword: geoscientificInformation Place: Place_Keyword_Thesaurus: Augmented FIPS 10-4 and FIPS 6-4 Place_Keyword: f17121 = Marion Place_Keyword: f17025 = Clay Place_Keyword: f17159 = Richland Place_Keyword: f17101 = Lawrence Place_Keyword: f17185 = Wabash Place_Keyword: f17047 = Edwards Place_Keyword: f17191 = Wayne Place_Keyword: f17081 = Jefferson Place_Keyword: f17055 = Franklin Place_Keyword: f17065 = Hamilton Place_Keyword: f17193 = White Place_Keyword: f17059 = Gallatin Place_Keyword: f17165 = Saline Place_Keyword: f17199 = Williamson Place_Keyword: f17087 = Johnson Place_Keyword: f17151 = Pope Place_Keyword: f17069 = Hardin Place_Keyword: f17127 = Massac Place_Keyword: f17153 = Pulaski Place_Keyword: f21007 = Ballard Place_Keyword: f21145 = McCracken Place_Keyword: f21039 = Carlisle Place_Keyword: f21105 = Hickman Place_Keyword: f21075 = Fulton Place_Keyword: f21083 = Graves Place_Keyword: f21035 = Calloway Place_Keyword: f21157 = Marshall Place_Keyword: f21139 = Livingston Place_Keyword: f21055 = Crittenden Place_Keyword: f21143 = Lyon Place_Keyword: f21033 = Caldwell Place_Keyword: f21221 = Trigg Place_Keyword: f21047 = Christian Place_Keyword: f21219 = Todd Place_Keyword: f21177 = Muhlenberg Place_Keyword: f21107 = Hopkins Place_Keyword: f21233 = Webster Place_Keyword: f21225 = Union Place_Keyword: f21101 = Henderson Place_Keyword: f21059 = Daviess Place_Keyword: f21149 = McLean Place_Keyword: f21183 = Ohio Place_Keyword: f21141 = Logan Place_Keyword: f47161 = Stewart Place_Keyword: f47125 = Montgomery Place_Keyword: f47147 = Robertson Place_Keyword: f18129 = Posey Place_Keyword: f18163 = Vanderburgh Place_Keyword: f18173 = Warrick Place_Keyword: f18147 = Spencer Place_Keyword: f18037 = Dubois Place_Keyword: f18125 = Pike Place_Keyword: f18051 = Gibson Place_Keyword: f18083 = Knox Place_Keyword: f18027 = Daviess 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, and Diehl, S.F., Drahovzal, J.A., Bear, G.W., and Sargent, M.L.
