This map depicts Canada's 2 great parts: the Shield and the Borderlands. The Shield consists of a core of old, massive, Precambrian crystalline rocks and covers half the country including most of Quebec and Ontario, the majority of Nunavut and Manitoba and all of northern Saskatchewan and eastern Northwest Territories. The Borderlands regions are formed by younger rocks and surround the Shield. The Borderlands' 7 physiographic regions include: the Appalachians in Atlantic Canada, the St. Lawrence Lowlands in southern Quebec and Ontario, the Interior Plains in central and northern Canada, The Cordillera in Western Canada and 3 arctic regions: Arctic Coastal Plain, Arctic Lowlands and Innuitian.

Contained within the 4th Edition (1974) of the Atlas of Canada is a map that shows physiographic regions across Canada. These regions are split into the Borderlands and the Shield.

Canada is a vast country comprised of a multitude of very different landscapes: Atlantic provinces, the Appalachians, St. Lawrence and Great Lakes lowlands, Canadian Shield, The Prairies, mountain ranges and high plateaus of the Canadian Cordillera, and northern Canada.

Nunavut’s mineral potential is substantial, which is why large and small companies are investing millions of dollars for prospecting and exploration in the volcanic and metamorphic rock of the Canadian Shield, particularly for gold, and more recently diamonds. This map locates the main exploration sites in 1998.

This map shows the location of the Shield physiographic regions. The Shield is divided into five great regions: Kazan Region, Davis Region, Hudson Region, James Region and Laurentian Region. Each of these five regions is divided by subareas, and each of these subareas has its own geological characteristics.

A geological province is an extensive region characterized by rocks and structures of varying types and ages. Canada has seventeen geological provinces consisting of a shield, platforms, orogens and continental shelves. Nunavut includes four of the geological provinces: Innuitian Orogen, Arctic Platform, Hudson Bay Lowlands, and Bear Province.

This GIS dataset is part of a digital compilation of the Precambrian geology of the Alberta portion of the Canadian Shield and Athabasca Basin. It is one of the datasets used to produce Alberta Geological Survey Map 537. The dataset displays locations on the Alberta shield where we took rock samples for 40 argon/39 argon dating. Attributes include crystallization and/or cooling age, mineral analyzed, sample identifier and rock type, literature reference, and analytical method.

Canada’s landmass is very diversified and comprises 7 distinctive areas called physiographic regions, each of which has its own unique topography and geology. Physiographic regions are large areas that share similar relief and landforms shaped by common geomorphic processes and geological history. Physiographic regions are often used to describe Canada’s geography to show regional differences in climate, vegetation, population and the economy.

This dataset collection contains three interrelated datasets mapping the location of Canada’s 7 different physiographic regions, their 21 subregions and many divisions (landforms).

Samples of rocks during reconnaissance geological mapping by Geological Survey of Canada field parties have been used to estimate the average abundance of some trace elements in the surface crystalline rocks of the Canadian Shield. The preferred values are as follows, in ppm: Ni, 19; Cu, 26; Zn, 60 ; Pb, 18; V, 59; Sc, 12 ; Y, 21; La, 71; Zr, 190 . Regional variations in trace element content of the rocks suggest that Pb is mobile under high grade regional metamorphism but that Ni , Co, Cu, Zn, V, and Scare relatively immobile and tend to be concentrated in rocks of granulite facies. Ni is more abundant and Pb and Zn less abundant in Archean rocks than in Proterozoic rocks.
