Document Summary
Economic geology brings a lot of people into geology Companies look for people that look for training (differentiation between rocks and minerals) logging core. Drillers go and take long drills of rock, and you must tell them what it is. The geology of ontario 4 layers (from toronto rocks by eyles) Layer cake diagram (see slide) 4 layers of ontario geology in it. The oldest layer is the one at the bottom, layer 1- that layer in ontario is more than a billion years old. Precambrian and aged comes from plate collision and mountains. Layer 2 tropical seas paleozoic hot and tropical; near the equator; however, over time the erosion wore it down to relatively flat. Peneplenation there was a rugged surface and it got worn down almost flat. It was being eroded by all those elements. Coral reefs started to flourish so we already know coral reefs make a rock called (sedimentary rock) limestone.
