The Geological Sciences Colloquium Series presents James Fox and Sebastian Barkett, Geological Sciences graduate students discussing their research on Friday, Oct. 11 at 2 p.m. in Clippinger 205.
James Fox
Fox presents “The Black Hand Sandstone Member of the Cuyahoga Formation as a Gilbert Delta Deposit.”
Abstract: Found in parts of Hocking Hills State Park, the Black Hand Sandstone is a familiar sight in south-eastern, Ohio. This research utilizes various sedimentological field and laboratory techniques to characterize the Black Hand Sandstone Member of the Cuyahoga Formation. Evaluating the combination of sedimentary structures and textures provide a means for this member to be interpreted in terms of a depositional environment.

Barkett presents “Physical and Chemical Parameters Determining Bacterial Growth of Acid Mine Drainage Sites in Southeast Ohio.”
Abstract: The generation of acid mine drainage (AMD) products from mining activity is the result of atmospheric oxidation of sulfide minerals when in contact with water through biogeochemical processes where bacteria play an important role. AMD yields products that are harmful to biological life, negatively influence the water chemistry, and alter stream sediments. This project aims to compare and describe the interactions of the water chemistry, sediments, physics of flow, and bacterial presence in AMD systems that are dominated by the elevated metals Fe, Al, and Mn. Four streams with contrasting chemistry will be studied for chemical composition, sediment analysis, discharge, and bacterial populations. Through these methods we expect to gain insight about the multifaceted nature of AMD interactions and improve existing remediation technologies.
