Canada The Munising Group or Formation is a 1,700 feet (520 m) thick, white to light grey [ 1 ] Cambrian sedimentary unit that crops out in Michigan and (to a lesser extent) Ontario . At one end of its extent, it comprises a basal conglomerate overlain by the Chapel Rock Member and the Miners Castle Member; elsewhere, it comprises the Eau ...
The Devonian Catskill Group or the Catskill Clastic wedge is a unit of mostly terrestrial sedimentary rock found in Pennsylvania and New York.Minor marine layers exist in this thick rock unit (up to 10,000 feet (3,000 m)).
The divisions of regional geology are drawn in different ways, but are usually outlined by a common geologic history, geographic vicinity or political boundaries. The regional geology of North America usually encompasses the geographic regions of Alaska, Canada, Greenland, the continental United States, Mexico, Central America, and the ...
Many of Canada's major ore deposits are associated with greenstone belts. [ 15 ] The Sturgeon Lake Caldera in Kenora District , Ontario, is one of the world's best preserved mineralized Neoarchean caldera complexes, which is 2.7 Ga. [ 16 ] The Canadian Shield also contains the Mackenzie dike swarm , which is the largest dike swarm known on ...
Western Europe and parts of Central Europe generally fall into the temperate maritime climate (Cfb), the southern part is mostly a Mediterranean climate (mostly Csa, smaller area with Csb), the north-central part and east into central Russia is mostly a humid continental climate (Dfb) and the northern part of the continent is a subarctic ...
The geology of Europe is varied and complex, and gives rise to the wide variety of landscapes found across the continent, from the Scottish Highlands to the rolling plains of Hungary. Europe's most significant feature is the dichotomy between highland and mountainous Southern Europe and a vast, partially underwater, northern plain ranging from ...
Dunvegan Sandstone. The Dunvegan Formation is composed of marine, and deltaic sandstone with thin shale interbeds in the Peace River Country. East of Dunvegan, Alberta it is of marine origin, and in its western reaches in British Columbia it was deposited in a continental facies, where the sandstone becomes more conglomeratic.
