Geology Of The Hagan Coal Basin, Earl P. Harrison

Earth and Planetary Sciences ETDs

This study was undertaken with the foremost objective of determining the stratigraphy and structure of the area, and correlating it with known surrounding areas.

The method of study was through geologic mapping in the field. The formational contacts, faults and other features were studied in the field with the aid of aerial photographs. The sections were measured in the field by hand-leveling with a Brunton compass up across the exposures. The lithology of the formations was studied as the sections were measured. The base map was taken from a planimetric map prepared by the Soil Conservation Service from aerial photos. …

Paleoecology Of The Brachiopoda, Celia Faith Hendren

Earth and Planetary Sciences ETDs

The immediate concern of the writer in the preparation of this thesis is not so much to give long statistical lists of conclusions (unfortunately this type of material is exceedingly scarce), but to sift the readily available facts in print and prepare a brief history of the work already accomplished on living and fossil Brachipoda. Where possible, there will be a discussion and evaluation of the views presented by different authors.
