Graduate Theses and Dissertations
The east-to-west oriented Arkoma Basin is a peripheral foreland basin or depositional trough that developed during the Carboniferous Period. This formation covers an aerial extent of approximately 33,800 square miles and spans from west-central Arkansas into southeastern Oklahoma (McGilvery, Manger, and Zachry, 2016; Perry, 1995). The Atoka Formation, deposited during the early Pennsylvanian, is the largest Paleozoic formation by aerial extent in the state of Arkansas and is located within and comprises the bulk of Arkoma Basin sediments (McFarland, 2004; Nance, 2018). This formation has been informally divided into three divisions, the lower, middle, and upper, based on their stratigraphic …

Geologic Mapping From Aerial Photography In The Boston Mountains, Northwestern Arkansas, Mikel R. Shinn
Journal of the Arkansas Academy of Science
Aerial photography has been employed to map stratigraphic and structural features in the Boston Mountains of Washington and Crawford Counties, Arkansas. Exposures of resistant stratigraphic units within the lower Atoka Formation were delineated on a series of large scale aerial photographs over an area of about 150 square miles. With the aid of a Bausch & Lomb Zoom Transfer Scope, the positions of the units were subsequently transferred to 1: 24,000 scale topographic base maps. The presense of east trending anticlines and synclines and a series of low displacement normal faults is reflected by either gradual or abrupt changes in …
