Abstract
The objective of this thesis was to date a Precambrian rock from the basement of Ohio. The Precambrian sample came from a disposal well drilled in Perry Township in Lake County, Ohio. The rock, which was of a granitic composition with secondary dolomite, was dated by the Rb-Sr whole rock method. The date of the rock was found to be 566±45 million years.
