Oct 22, 2019 Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves. For instance, most limestone forms at the bottom of the ocean from the precipitation of calcium carbonate and the remains of marine animals with shells. If limestone is found on land, it can be assumed that the area used to be under water.

Feb 07, 2006 Blueschists are found only in rocks formed during the last 120 million years, and therefore are restricted in Canada to the Cordillera. Eclogites are also generally restricted to relatively young rocks, with the worlds only occurrence of Archean more than 2.5 billion years old eclogites being discovered recently in the Canadian Shield in northern Saskatchewan.

Geology of 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 Canadas gold, copper, iron, zinc and diamonds.

Feb 16, 2019 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.

Feb 16, 2019 Igneous Rocks are the most primitive of rocks they come directly from molten rock and crystallize in varying ways to become rocks. Since the other types of rocks metamorphic and sedimentary are derived from igneous rocks to start with it is important to know the basics of where the source rock came from.

Nov 23, 2020 Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earths surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. These rocks often have distinctive layering or bedding and create many of the picturesque views of the desert southwest.
