I joined Earth Sciences about 8 months ago, moving back to Waterloo from Sudbury where I worked in Klohn-Crippen's Mining Group for several years, consulting on a variety of issues related to Rock Stability Assessment and Improvement, as well as Mining and the Environment. Prior to that time, I worked for a number of years in Geological Engineering Research with the University of Toronto, CSIRO in Australia and the Geomechanics Research Centre at Laurentian University. I have also dabbled in permafrost research and highway construction and design along the way.
What you are looking for is sedimentary rocks. These are the ones that look like they have layers. They do. The rocks were created layer after layer as dirt or animals fell to the bottom of a lake, marsh or sea. Granite and rocks that were formed from volcanoes generally do not contain fossils. It was just too hot.
A four-ton grey syenite rock striped with deep blue sodalite arrived on the Waterloo campus by truck last May, and settled into the Geological Garden among 50 tons of other rocks, mainly from Ontario locations. Tended by Peter Russell, the rock garden has been growing since 1986. The new rock was donated by Andy Christie, owner of the Princess Sodalite Mine, east of Bancroft. It will be dedicated to the memory of Elizabeth Edwards, an Earth Sciences staff member who died in 1997.
