b'Petrologic and Petrographic Analysis of the Altamaha Formation in the Soperton Area, Treutlen County, GeorgiaWiley M. Griffin IV, Department of Physics, Astronomy, Geosciences and Engineering Studies Faculty Sponsor: Dr. Mark S. Groszos, Department of Physics, Astronomy, Geosciences and Engineering StudiesThe Miocene Altamaha Formation consists of well-indurated sandstones that crop out as prominent exposures in the eastern Coastal Plain of Georgia. The tops and bottoms of these exposures are covered, but the unit is at least 6 meters thick. Outcrop, hand sample, and petrographic analysis shows the unit is composed primarily of poorly sorted, angular to sub-angular quartz grains with subordinate feldspar grains and varying degrees of clay matrix. Most exposures are white in color with abundant secondary staining from iron oxides. Grain-size ranges from fine/medium sands to pebbly conglomerates. Some samples show distinct bi-modal grain-size distribution.The clay matrix is interpreted to be the result of in situ weathering of feldspar grains. If this interpretation is correct, these rocks were originally deposited as arkosic sandstones. Samples were collected from seven locations along highway 221 south of Soperton, Georgia, and along highway 46 east of Soperton, Georgia.Transient Conductive Heat Transfer Analysis of a Metallic BarJustin Crance, Department of Physics, Astronomy, Geosciences and Engineering StudiesFaculty Sponsor: Dr. Barry Hojjatie, Department of Physics, Astronomy, Geosciences and Engineering StudiesIn this study, we develop an experimental heat transfer system and the corresponding model to analyze the transient conductive heat transfer through a bar of unknown thermal conductivity. Using the analytical model and comparing it to the experimental data a value for the thermal conductivity of the unknown metal was obtained. The analytical model was validated using the material properties and geometric dimensions corresponding to a commercial system made using an aluminum bar. There was a small difference between the experimental results and those obtained by the model due to imperfect insulation.61'
