Summer Research Students Show Off Their Work

The 2012-13 school year has begun here at Denison, and tradition dictates that all the hardworking research students get to show off the science they’ve done. This year three Geoscience majors presented their summer research at the annual Summer Research Symposium. Check them out:

Mariann Bostic, presenting on stratigraphy of the earliest stages of the Kungurian Stage in the Pequop Mountains, Nevada(advisor: Kate Tierney)

April Strid presenting on models for carbon cycling in soils due to land use (advisor: Tod Frolking)

Amy Williamson presenting on pressure and temperature determinations for the Eagle Lake Pluton, California (advisor: Erik Klemetti)

Job well done … and now onto their senior year!

Flint Ridge, Ohio

Being in the middle of Ohio as a petrologist you find out that there aren’t a lot of crystalline rocks to gaze upon – at least without drilling a 5-km hole directly below one’s feet. However, there are some cool localities that exhibit mineralization that might not be igneous or metamorphic basement, but at least have some great examples of minerals for an introductory rocks and minerals course.

Views from an airplane

Some great images of the southwest to start off the week, courtesy of Dr. David Greene.

“Here are a couple of pictures I took from the window of a Southwest Airlines flight coming into Las Vegas, as I was returning to Ohio at the end of my field season. The yellow-orange rocks in the foreground are Jurassic Aztec Sandstone, and the grey-green vegetated slopes above with the prominent grey stripes are Cambrian limestone of the Bonanza King Fm.
