These mountains formed over tens of millions of years as a result of tectonic collisions between the continents and crustal plates located in what is now the Pacific Ocean basin. The crustal plates included slivers (terranes) of volcanic islands, ocean floor and other small continents that collided with and remained stuck onto (accreted) the margins of the continents. These mountain-building collisions were marked by igneous intrusions and volcanism, deformation (folding, faulting, and metamorphism) and uplift. In British Columbia the Canadian Cordillera is made up of five, northwest-trending morphogeological belts: Foreland, Omineca, Intermontane, Coastal and Insular. They are defined by their distinct geology and the mountain-building processes that formed them, and are separated from each other by faults. Geoscientists have determined that the rocks in the Foreland belt formed along the edge of ancient North America. However, rocks forming the belts further west formed elsewhere and were accreted to the continent between 185 and 50 million years ago. The unique geological characteristics and mountain-building history of each belt determine the mineral resources each one contains.

Bibliography: O M IN KA AS AL E C Foreland Belt, represented by the Rocky Mountains, is made up mostly of a great thickness (>15 km) of ancient sedimentary rocks. Most are between 700-50 million years old, but some are up to 1.5 billion years old. They are composed of sediment that was eroded from and deposited along the western edge of the ancient continent. During mountain building they were thrust eastwards for at least 150 km onto the continent. Fording River Invermere W.R.P.

Most of these metamorphic rocks formed from pre-existing sedimentary rocks. Some of these are similar in composition to sedimentary rocks in the Foreland, while others are more similar to those in the Intermontane. This complexly deformed belt represents the exposed roots of a deeply-eroded mountain chain. It marks a collision zone that formed when the Intermontane was accreted to North America. • Intermontane Belt, a region of high plateaus and rolling uplands, is made of ancient to Recent volcanic and sedimentary rocks that are intruded in many areas by granitic rocks. The oldest of the volcanic and sedimentary sequence (370-180 million years) represents ocean floor and volcanic island arc terranes that formed offshore and were accreted during middle Jurassic time (165-172 million years ago). The granitic rocks are related to ancient island arc volcanism and to later accretion of Insular belt rocks. • Coast Belt includes the Coast and Cascade mountains and extends up to the Yukon. It is made up mostly of 185 to 50 million year old granitic rocks, plus scattered remnants of older, deformed sedimentary and volcanic bedrock into which the granitic bodies have intruded. (Similar, undeformed sedimentary and volcanic rocks occur in both the Intermontane and Insular belts.) Similar to the Omineca, this belt marks a collision zone. It represents the roots of a deeply-eroded volcanic mountain chain that formed during accretion of Insular belt rocks to North America. • Insular Belt includes Vancouver Island, the Queen Charlotte Islands, and the bedrock forming the seafloor out to the toe of the continental slope about 100 km west of Vancouver Island. It is made up mostly of ancient (350-180 million years) volcanic and sedimentary rocks, which are intruded locally by granitic rocks. Like those in the Intermontane, the volcanic and sedimentary rocks represent exotic terranes that formed out in the ocean basin and were accreted to the continent by mid-Cretaceous time (100-115 million years ago). IN FO • E E N TA E N NO RM TA O TNE IMN R ND LA A RE EC IN OM T L TA AS CO SU IN R LA The variety and distribution of mineral resources in British Columbia are directly related to the province’s complex and unique geology. Some of these resources, such as limestone, occur and are mined in many regions around BC. Others occur or predominate in only certain morphogeological belts as dictated by their bedrock geology and the mountain-building processes that overprint them (Dawson, K. M., et al., 1991). Major coal deposits, for example, are predominant in the sedimentary sequences of the Foreland and Insular belts, while economic copper-molybdenum porphyry deposits are predominantly associated with granitic intrusions in the Intermontane. Where BC’s mineral resources are discovered depends on geology. Where they are extracted depends on economic, logistical, and environmental considerations.
