What is the Canadian Shield rich in?

Northern Ontario History

The Canadian Shield is a result of tectonic processes, where smaller continental landmasses drifted together and collided over hundreds of millions of years. The Canadian Shield is one of the world’s richest areas in terms of mineral ores, such as nickel, gold, silver, and copper.

Is the Canadian Shield bedrock?

Precambrian rock is the major component of the bedrock. The North American craton is the bedrock forming the heart of the North American continent and the Canadian Shield is the largest exposed part of the craton’s bedrock.

What provinces make up the Canadian Shield?

The Canadian Shield stretches from Labrador to the Arctic. It covers parts of Saskatchewan and Alberta. It covers much of Quebec, Ontario, Manitoba and the Northwest Territories. It is 5 million km2.

Is the Canadian Shield made of granite?

The Shield forms the ancient geological core of the North American continent and has some of the oldest rocks found on Earth. These ancient rocks are largely hard and resistant granite, gneiss and volcanic rocks that were formed more than a billion years ago. Canadian Shield rocks underlie a third of Canada.

How thick is the Canadian Shield?

The sedimentary cover is less than a mile thick on the platform, but it increases to about 2.5 miles (4 km) in the Hudson Bay, Michigan, Williston, and Illinois sedimentary basins and to 4 miles (6 km) and more in troughs adjacent to the peripheral orogenic belts.

Why is the Canadian Shield almost completely uninhabited?

This region has dry, barren, and mostly uninhabited areas. This is largely because it has long, cold winters with heavy snow and perpetually frozen soil.

What kind of rock is the Canadian Shield made of?

The Canadian Shield is the ancient core of the North American Continent. It is composed mainly of highly metamorphosed granite, with smaller areas of metamorphosed sedimentary and igneous rocks and some areas of relatively horizontal but still quite ancient sedimentary rocks.

What is granite made of?

granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth.

Where was the eroded material from the Shield deposited?

ANSWER: (p. 97) The eroded material or “sediments” from the Shield (see Fig. 10-8) was moved by rivers and deposited in shallow seas surrounding the Shield. Over millions of years, these sediments were compressed into layers of sedimentary rock to form the bedrock that today underlies part of every province.

Are there fossils in the Canadian Shield?

Although some Precambrian fossils such as stromatolites can be found in northern Ontario in the Canadian Shield, most of the fossils in Ontario will be found in the Paleozoic rocks that record the life that lived in the shallow seas emergent during the times.

Is there limestone in the Canadian Shield?

Over time, they formed sandstones and shales, interleaved with limestones formed in clearer waters. Today, the land between the shield and the St. Lawrence Valley produced by these processes (the country north of Belleville in present-day Ontario) is a region of bare limestone plains, thin soils, and abandoned farms.

What animals are in the Canadian Shield?

Characteristic wildlife include moose (Alces alces), caribou (Rangifer tarandus), black bear (Ursus americanus), lynx (Lynx canadensis), snowshoe hare (Lepus americanus), wolf (Canis lupus), sharp-tailed grouse (Tympahuchus phasianellus), ruffed grouse (Bonasa umbellus), American black duck (Anas rubripes) and wood …

Why are there no dinosaurs in Ontario?

A: Ontario dinos? They almost certainly lived here, but there are virtually no rocks of the right age here: those rocks are too old. There are some rocks of right age and type in far northern Ontario. … I hope to find Ontario’s first dino some day.

What dinosaurs lived in Ontario Canada?

Well-known dinosaurs first named from Canadian specimens include Albertosaurus, Centrosaurus, Corythosaurus, Dromaeosaurus,Gorgosaurus, Lambeosaurus, Pachyrhinosaurus, Parasaurolophusand Styracosaurus.

How old is the granite of the Canadian Shield?

DID YOU KNOW? The Canadian Shield contains some of the oldest rocks on Earth. In 2008, researchers estimated rock found on the northern shore of Hudson Bay, 40 km south of Inukjuak, to be 4.28 billion years old. Its age means the rock was created approximately 300million years after the formation of Earth.

What was Canada like millions of years ago?

The land was barren, likely dry and rocky. Locally, there may have been microbial soil crust. There was no vegetation as we know it today – no grass, no trees, no plants. This photo shows what the land may have looked like 500 million years ago, during the Cambrian Period.

Can you find shark teeth in Canada?

Fundy Geological Museum: Shark Teeth! The Fundy Geological Museum’s primary field site (Wasson Bluff, NS) is known for being the location of Canada’s oldest dinosaur, but there is so much more there! … Shark teeth are made of dentin (like our teeth), which is a hard substance the fossilizes well.

What happens if you find dinosaur bones on your property Canada?

Violation of the Act is punishable by fines of up to $50,000 and/or one year in prison. If you find a fossil, the location is as important as the fossil itself.

Who lived in Canada before the natives?

Everyone has to come from somewhere, and most archaeologists believe the first peoples of Canada, who belong to what is sometimes called the Amerindian race, migrated to western North America from east Asia sometime between 21,000 and 10,000 B.C. (approximately 23,000 to 12,000 years ago), back when the two continents …
