Elora and Fergus geology

What on Earth: Volume 7 2011

A geological view of Elora and Fergus

One of the most scenic features of southern Ontario is the Elora gorge on the Grand River. The river has cut down about 30 m into dolostone (related to limestone) in the time since the last glacier ice melted away about 14000 years ago.

In natural science, the frontier of the unknown is never far away. One of the frontiers lies below our feet. What lies below the surface of the ground? How did the University campus get to be so hilly?
In May, 1976, a hole was drilled by the Department of Earth Sciences drilling rig beside the Chemistry Building, in order to get a glimpse into the unknown below us.

Homer Watson Park geology

What on Earth: Volume 7 2011

Kitchener: The Homer Watson Park section

P. F. Karrow

On the west bank of the Grand River, at Homer Watson Park, is an exposure of the subsurface materials which reveals something of the geological history of the Kitchener area. The exposure was created by river bank erosion by the Grand River. From time to time the exposure is covered by slumped material and vegetation, but this varies with river flooding and weather conditions.

My interest in geology goes back as far as I can remember. My dad’s family is from Bancroft, Ontario, the self-styled mineral capital of Canada, so for every Christmas my Grandparents would give me beautiful rock samples from their area.
We had a fantastic Gem and Mineral Show this year. The change from a Saturday/ Sunday show to a Friday/ Saturday show gave students the opportunity to visit the show between classes. 
We would like to thank everyone for coming out to see the show and showing your support for the Sciences.

After studying pictures and small pieces of rocks and minerals in first year at the University of Waterloo, I finally got to experience the practical side of geology this summer working for the exploration department of a gold company.

Marl

Paul Karrow

Department of Earth and Environmental Sciences, University of Waterloo

Marl is a soft, light-coloured (white to pale gray or) mud-like sediment, seen in shallow waters of some small lakes or ponds, or under swamp lands, where it typically is covered by black organic sediment (Figure 1).
