The geology of Ontario is the study of rock formations in the most populated province in Canada- it is home to some of the oldest rock on Earth. The geology in Ontario consists of ancient Precambrian igneous and metamorphic rock which sits under younger, sedimentary rocks and soils. Around 61% of Ontario is covered by the Canadian Shield. The ...
The Athabasca basin, a historical fluvial siliciclastic basin with sediments from the Hudsonian mountains with the occasional rare marine sequence. [16] [dead link ] The Athabasca basin was formed during the Statherian or Paleohelikian 1.7 to 1.6 billion years ago when coarse fluvial and marine clastic sediments were laid down containing gold, copper, lead, zinc, and uranium oxides.
Synonyms in this case include rock dust, rock powders, rock minerals, and mineral fines. The igneous rocks basalt and granite often contain the highest mineral content, whereas limestone , considered inferior in this consideration, is often deficient in the majority of essential macro-compounds, trace elements, and micronutrients .
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
It is also the most unstable volcanic massif in Canada, which has dumped clay and rock several meters (yards) deep into the Pemberton Valley at least three times during the past 7,300 years. Hot springs near the Mount Cayley and Mount Meager massifs suggest that magmatic heat is still present.
The volcanic rocks are between 1.49 and 2.3 billion years old. The Nain Province is subdivided into the Makkovik-subprovince, which is mainly made up of the 25,000 foot thick Aillik Group quartzofeldspathic, argillite, limestone, conglomerate, paragneiss and iron formations. [citation needed]
The word badlands is a calque from the Canadian French phrase les mauvaises terres, as the early French fur traders called the White River badlands les mauvaises terres à traverser or 'bad lands to traverse', perhaps influenced by the Lakota people who moved there in the late 1700s and who referred to the terrain as mako sica, meaning 'bad ...
The Clay Belt is a vast tract of fertile soil in Canada, stretching across Cochrane District in Ontario and Abitibi County in Quebec, covering 180,000 square kilometres (69,000 sq mi) in total [1] with 120,000 square kilometres (46,000 sq mi) of that in Ontario. [2]
