Progress Report of the Kansas Basement Rocks Committee and Additional Precambrian Wells

Abstract

The Kansas Basement Rocks Committee is actively collecting data pertaining to Precambrian rocks of Kansas. An additional 84 wells known to encounter the Precambrian bring the total number of known Precambrian tests in Kansas to about 2,200 as of December 31, 1961. A generalized configuration map of the surface of Precambrian rocks shows major post-Mississippian structural features in the state. Potassium-argon age dates for five samples range from 1165 to 1460 million years.
