I've been searching for geological information for Alexander County,
North Carolina, specifically aeromagnetic coverage and high resolution
gravity anomaly information. The information can be in paper or
digital form.
What I've found so far are the following:
1. Daniels, David L. and Zietz, Ididore. 1981. Aeromagnetic map of the
Charlotte 1 degree x 2 degree quadrangle, North Carolina and South
Carolina. Map I-1251-A. US Geological Survey: Reston, VA. Price $4.00

10. Wilson, William F. 1962. Beryl occurrences in North Carolina.
Information Circular 17. North Carolina Geological Survey: Raleigh.
Price: Out-of-print
This publication lists beryl occurrences in Alexander, Ashe, Burke,
Catawba, Cleveland, Gaston, Iredell, Jackson, Lincoln, Macon,
Rutherford, Swain, Transylvania, Wake, Warren and Yancy counties. From
the search: patterns of diabase dikes that occur in ... beryl
occurrences in Alexander, Ashe, Burke ... Counties in North Carolina.
The report ... and twenty county maps showing

North Carolina Dikes, seems to describe the 1985 geologic map but notes
there is a 1993 digital file revision. The map which accompanies the
online description does not show dikes as far west as Alexander County
with one exception, a southeast to northwest dike just inside the
western boundary of Lincoln Cty. and across the eastern end of Burke
Cty.

North Carolina Faults refers to the same publication as above. The
accompanying map shows no faults crossing Alexander County but does
show a west southwest to east northeast fault in Redell, immediately
east of Alexander.
13. The official geologic map of North Carolina (1985) as published by
the NC Geological Survey and the US Geological Survey. This information
consists of three datasets: geologic formations, dikes, and faults; all
are distributed together. 1:250,000 -- Base maps used to develop the
1985 NC Geologic Map
14. Lists of theses in geology of North Carolina were also checked and
nothing found pertaining to Alexander County.
Have I missed anything? Ideally larger scale aeromagnetic and gravity
anomaly maps would be desireable. Is there a library near Alexander
County that has all or most of this material for consultation?
Thanks for any help you can offer.
