Sedimentary Rocks - Canada Mines

2019/02/16 · Given the ages of rocks in Northwest Ontario, the vast majority of sedimentary rocks are now metamorphosed to some extent but can usually be recognized for the sedimentary rocks they were. This is essential to understanding what type of environments they formed and were deposited in and as such their geological history is essential in exploration for precious minerals like gold and platinum.

2019/10/22 · Coal is a sedimentary rock formed over millions of years from compressed plants. Inorganic detrital rocks, on the other hand, are formed from broken up pieces of other rocks, not from living things. These rocks are often called clastic sedimentary rocks. One of the best-known clastic sedimentary rocks is sandstone.

Sedimentary rock - Wikipedia

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological ...

Geology of Canada - Natural Resources Canada

Canadian geology spans four billion years of Earth history. The oldest rocks are preserved in the stable Archean crustal blocks of which the largest include the Superior, Slave, Hearne and North Atlantic cratons. These blocks are also the repository for much of Canada’s gold, copper, iron, zinc and diamonds.

21.2 Western Canada during the Precambrian – Physical Geology

The oldest rocks in British Columbia are the strongly metamorphosed sedimentary, volcanic, and intrusive rocks of the Monashee Complex, situated to the west of the Columbia River near Revelstoke (Figure 21.7). Aged around 2 Ga, these may actually be part of Laurentia.

21.1 Geological History of Canada – Physical Geology

These are at least partly made up of sedimentary rocks that were deposited along the coasts and then folded, faulted, and uplifted during continental collisions. The term Laurentia is geologically equivalent to the term Canadian Shield , although the latter is generally considered to be the area where the ancient Laurentian rocks are exposed at the surface and not covered with younger rocks.

what kind of rock is formed from sediments?

Cross-bedded sandstone of the Gunsight Formation of the Mesoproterozoic Lemhi Group. These rocks often start as sediments carried in rivers and deposited in lakes and oceans.

2015/03/04 · This kind of rock is found in many places in Canada (eg, near the Amulet-Dufault ore body near Noranda, Qué) and in the contact metamorphic rocks of BC's coastal ranges. Gneiss [Ger "spark," for its sparkling appearance] is a coarse-grained rock with distinct layers made up of different proportions of minerals.

East Central Ontario minerals | Earth Sciences Museum ...

The sedimentary rocks of the area were altered to marble, amphibole, paragneiss and quartzite, while the volcanic rocks were altered to mostly amphibole. An area called Quadeville, in south eastern Ontario, is well known for its large pegmatite, which was formed when the Earth’s crust deformed and cracked during this mountain building time.
