A geologic study, both field and laboratory, was made of the 12,000 foot thickness of steeply dipping Freda for­ mation exposed along this river. The field study Includes mapping of sedimentary structures In an effort to determine the dominant current directions during deposition of the formation. Pebble and quartz grain orientation as well as heavy mineral and rock composition analyses were made In the laboratory to supplement the field work.

  • Subsurface Facies Analysis of the Devonian Berea Sandstone in Southeastern Ohio
    SUBSURFACE FACIES ANALYSIS OF THE DEVONIAN BEREA SANDSTONE IN SOUTHEASTERN OHIO William T. Garnes A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2014 Committee: James Evans, Advisor Jeffrey Snyder Charles Onasch ii ABSTRACT James Evans, Advisor The Devonian Berea Sandstone is an internally complex, heterogeneous unit that appears prominently both in outcrop and subsurface in Ohio. While the unit is clearly deltaic in outcrops in northeastern Ohio, its depositional setting is more problematic in southeastern Ohio where it is only found in the subsurface. The goal of this project was to search for evidence of a barrier island/inlet channel depositional environment for the Berea Sandstone to assess whether the Berea Sandstone was deposited under conditions in southeastern Ohio unique from northeastern Ohio. This project involved looking at cores from 5 wells: 3426 (Athens Co.), 3425 (Meigs Co.), 3253 (Athens Co.), 3252 (Athens Co.), and 3251 (Athens Co.) In cores, the Berea Sandstone ranges from 2 to 10 m (8-32 ft) thick, with an average thickness of 6.3 m (20.7 ft). Core descriptions involved hand specimens, thin section descriptions, and core photography. In addition to these 5 wells, the gamma ray logs from 13 wells were used to interpret the architecture and lithologies of the Berea Sandstone in Athens Co. and Meigs Co. as well as surrounding Vinton, Washington, and Morgan counties. Analysis from this study shows evidence of deltaic lobe progradation, abandonment, and re-working. Evidence of interdistributary bays with shallow sub-tidal environments, as well as large sand bodies, is also present.
