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 Scotian Shelf is a geological formation, part of the Continental shelf, located southwest of Nova Scotia, Canada. [1] It covers an area of 120,000 square kilometres (46,000 sq mi), [2] is 700 kilometres (430 mi) long and ranges in width from 120 to 240 kilometres (75 to 149 mi). It has an average depth of 90 metres (300 ft). [3]
Superficial deposits (or surficial deposits [1]) refer to geological deposits typically of Quaternary age (less than 2.6 million years old) for the Earth. These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine .
Geologic map of North America. The geology of North America is a subject of regional geology and covers the North American continent, the third-largest in the world. Geologic units and processes are investigated on a large scale to reach a synthesized picture of the geological development of the continent. The divisions of regional geology are ...
Geologic units and processes are investigated on a large scale to reach a synthesized picture of the geological development of the country. Geologically, Canada is one of the oldest regions in the world, with more than half of the region consisting of precambrian rocks that have been above sea level since the beginning of the Palaeozoic era.

The Ontario Geological Survey (OGS) is an administrative Branch of the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry.It is responsible for documenting and communicating the Geology of Ontario, and manages the Abandoned Mines Information System (AMIS), the Ontario Assessment File Database (OAFD), the Ontario Drill Hole Database (ODHD), the Ontario Mineral ...
Only the most general of rock distinctions are made on the existing geological map, and only a very rudimentary understanding of the surficial geology exists. Currently there is no publicly available, regional-scale surficial (till) geochemical data which is essential for understanding exploration potential for metals and diamonds.
The Fort St. John Group is a stratigraphic unit of Lower Cretaceous age in the Western Canada Sedimentary Basin. [2] It takes the name from the city of Fort St. John , British Columbia and was first defined by George Mercer Dawson in 1881.
