Abstract

"PURPOSE AND SCOPE OF INVESTIGATION The major purpose of this investigation was to determine by a comprehensive study various geological and magnetic characteristics of buried and resurrected Precambrian hills of the Central Ozarks. A second important objective was the determination of characteristics which might aid in the location of buried Precambrian hills. A final objective was the testing of the magnetic surface integration method for identification and determination of depth of buried Precambrian hills.

This investigation is limited to buried and resurrected Precambrian hills of the Central Ozarks. It is concerned primarily with the structure and stratigraphy of sediments adjacent to buried and resurrected Precambrian hills, and magnetic anomalies associated with the hills. Other geological characteristics are considered in less detail.

Six areas within the Central Ozarks were selected for detailed mapping and study. The structure and stratigraphy of Upper Cambrian and Lower Ordovician sediments were examined in order to determine environments of deposition, the origin of peripheral dips, and the origin of tangential and radial jointing noted during the study. Magnetic characteristics were surveyed at several localities, and efforts were made to reproduce the magnetic fields associated with the Precambrian hills by use of the surface integration method. Configuration of the Precambrian topography and its relationship to overlying and surrounding sediments was also considered.

The petrology and structure of Precambrian igneous rocks of which the hills are composed are not considered in detail in this dissertation. In addition geochemical and other geophysical aspects remain to be examined in greater detail by future workers"--Introduction, pages 1-2.
