Ohio Wesleyan Senior Shares Research Results at Regional Meeting

Eric Mumper Makes Poster Presentation at Geological Society of America Annual Meeting

DELAWARE, OHIO – Ohio Wesleyan University student Eric Mumper wants to know why a Delaware-area shale rock formation contains large cannonball-like structures and whether these “carbonate concretions” are tied to the shale’s potential as a source of natural gas. 

The senior geology major and biology minor from Delaware, Ohio, believes understanding the microbiological processes at work in the creation of the black Devonian shale could “shed light on how to exploit modern microbial systems to develop sustainable sources for carbon fuels in the future.”

Mumper has been studying the issue with Ohio Wesleyan geology professor Karen Fryer, Ph.D., and he shared the results of their work in a poster presentation at the 46th annual meeting of the Geological Society of America North-Central Section. The meeting was held April 23-24 in Dayton.

“My research was to document the sizes, shapes, and composition of these iron concretions and to develop a model for their formation,” said Mumper, who plans to pursue a doctorate in geomicrobiology at Ohio State University this fall. “I was able to document four stages of development and built a model for this growth. The growth of these iron concretions reveals some interesting information about what conditions were like during the Late Devonian here in Ohio.”

Mumper’s research included using reflected light microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy to examine the shale and the concretions.

He said making the poster presentation helped to validate his work and ensure he was on the right path in the research.

“The presentation was an opportunity to put all of my work and interpretations to the test,” Mumper said. “I knew that there would be a number of geologists at the meeting who had much more experience than I do. If my model held up to their scrutiny, I would know that I did a good job. And it did! So much confidence was gained in presenting.”
