Seasat Orbital Radar Imagery Applied To Lineament Analysis And Relationships With Hydrocarbon Production In The Wartburg Basin Area, Tennessee, S. E. A. Brite

Masters Theses

Seasat, an orbital synthetic aperature radar launched in 1978, has produced high-resolution imagery enhancing over 1186 observed linear topographic indentations or lineaments in the Wartburg Basin area of east-central Tennessee. The main objectives of this thesis are to verify these lineaments in the field, to compare them with aerial photographic lineaments in the same area, to statistically analyze lineament trends, and to compare lineaments with oil and gas trends in the Wartburg Basin area.

Lineaments from Seasat imagery were located in the field with a high degree of accuracy. Three distinct lineament systems were derived from lineament orientations, their grouping …

The Geology And Origin Of The Sawyer Uranium Prospect, Live Oak County, Texas, Charles L. Brewster

Masters Theses

The Sawyer uranium prospect is a subsurface uranium occurrence hosted within the basal Oligocene Catahoula Formation of the Texas coastal plain. The host rocks consist of tuff-ball conglomerate, tuffaceous sandstone and tuffaceous claystone whose geometry and lithological characteristics indicate that they are the products of a crevasse-splay depositional environment. Compositionally, these lithologies are feldspar-depleted litharenites, with the feldspar depletion due to the corrosive, ore-forming processes. These sediments display pedogenic to early diagenetic features including diffuse to discrete micrite nodules, clay cutans, fresh to partially argillized glass shards, clay booklets, authigenic zeolites and sulfides, paleosoil horizons and calcite cement.
