Masters Theses

Abstract

"Geologic mapping has been completed for the northern half of the Ellington Quadrangle, Missouri. Rocks exposed in the thesis area are Precambrian and Paleozoic in age. The Precambrian rocks are granites and felsite. The Paleozoic rocks include the Potosi and Eminence Formations, of Upper Cambrian age, and the Gasconade Formation of Ordovician age. Distinction between the Potosi and Eminence Formations is difficult because of conformable and transitional relationships. In the thesis area sufficient evidence was available to separate the dolomites of the Potosi and Eminence as mappable units. This mapping should be useful as a basis for more detailed geologic investigations, both economic and academic.

The area is influenced by the buried knob topography characteristic of the St. Francois Mountains. Structure and deposition were found to be directly associated with the buried Precambrian erosion surface.

Geologic data such as measured stratigraphic sections and outcrop locations are included and should provide readily available information useful in further mapping in adjoining areas" -- Abstract, p. ii
