On September 23-24, 2017, the Advanced Structural Geology class enjoyed the unseasonably hot weather in northern Wisconsin to look at the Mountain Shear Zone. Did you know there is a Mountain, Wisconsin? Well there is… and 1.8 billion years ago, some major mountains were located there! The class looked at rocks that deformed deep within that mountain belt and are exposed on the surface today. The highlighted rocks included small-scale shear zones across granitic gneiss and deformed metamorphosed pillow basalts.
The students in the class are Andrew Jungbluth, Gayantha Kodikara, Chad Martin, and Sheryl Stephenson. They were led by Dr. Dyanna Czeck from UWM and Dr. Prajukti Bhattacharyya from UW-Whitewater. Photos all courtesy of Gayantha Kodikara.
