Geologic belts of Western Canada. The geology of British Columbia is a function of its location on the leading edge of the North American continent.The mountainous physiography and the diversity of the different types and ages of rock hint at the complex geology, which is still undergoing revision despite a century of exploration and mapping.

The landforms of British Columbia include two major continental landforms, the Interior Plains in the province's northeast, the British Columbia portion of which is part of the Alberta Plateau. The rest of the province is part of the Western Cordillera of North America , often referred to in Canada as the Pacific Cordillera or Canadian Cordillera.
Fiord Ranges - Geophysical Survey of Canada designation for the Kitimat Ranges, plus the lower portion of the Pacific Ranges between the icefield-massifs at the core of the range and the coast. [3] The latter are sometimes labelled the Front Ranges on some topographic maps but are not in evidence on modern versions. Pacific Ranges. Chilcotin Ranges
Overlying these two geological formations are the Nido and Spectrum formations, which were deposited between 6 and 3 million years ago during the second magmatic cycle. The fifth oldest geological formation comprising the Kitsu Plateau is the Big Raven Formation, which was deposited during the fifth magmatic cycle in the last 20,000 years. [4] [5]
[2] [6] It was required for geology reporting purposes since Jack Souther, a volcanologist of the Geological Survey of Canada, was studying the area in detail between 1970 and 1992. [ 7 ] [ 8 ] [ 9 ] The escarpment was named for its association with Mess Creek , a tributary of the Stikine River which flows into Sumner Strait of southeast Alaska .
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
