SRU geoscientists take closer look at cooling history of Canadian rock samples
To the unknowing observer, the rock wall shouldering the Trans-Canada Highway, where the road sidles the banks of Kama Bay near Nipigon, Ontario, is just that, a rock wall. But for a faculty-student research team at Slippery Rock University, the site demands a much closer look.
Fortunately for Logan McIntyre, a junior dual environmental geoscience and modern languages and cultures major from Volant, she doesn't have to travel to Canada to check the rocks out. Instead, she is looking at dozens of rock samples from the outcrop, each the size of a postage stamp, magnified 200 to 500 times on a computer screen at an SRU laboratory and under a scanning electron microscope at Indiana University of Pennsylvania. The samples came from a 1.4-meter slab of diabase igneous rock taken from the Kama Bay outcrop in 2008 by Michael Zieg, SRU professor of geography, geology and environment.
