Kansas Geological Survey Open-file Report 2001-55 |
Interpreted lineaments from Gravity and Magnetics maps highlight
some of the basement structure in the area. The midcontinent rift
system is a north-northeast-south-southwest trending fault zone.
The northwest-southeast trending faults along the Central Kansas
uplift appear to be offset structures of the midcontinent rift
(Baars and Watney, 1991). Stratigraphic relationships suggest
reactivations of these zones of basement weaknesses throughout
the Paleozoic. These trends are evident at many different scales
on the Pre-Pennsylvanian Arbuckle erosional surface, from the
orientation of the main drainage across the Central Kansas uplift
to the major axis of individual
dolines.
