Terrane boundaries

Possible locations of various Cordilleran terranes during the Permian (ie. prior to 250 m.y.)

Passive margin A passive ocean- continent margin existed from around 700 m.y to around 200 m.y. ago. A thick sequence of sediments – clastics and limestones - accumulated in this time.

Subduction Subduction of oceanic plate beneath North America. Subduction- related volcanism existed. Approach of micro-continents from the southwest.

Intermontane Super-terrane Accretion of the Intermontane Super- Terrane and consequent thrusting and folding of existing sedimentary rocks into the Rocky Mountains. Approach of more micro-continents. Subduction related volcanism and intrusive bodies. The Intermontane terrane is mostly volcanic and sedimentary rocks that formed a long way away.

Coast range plutonic complex Formation of the Coast Range Plutonic Complex. Accretion of the Insular Super Terrane. Ongoing subduction of the Juan de Fuca Plate beneath B.C., Washington and Oregon. Further uplift of the Rocky Mountains.

Coast Range Plutonic Complex

Extent of ice cover at the height of the last glacial advance (ca. 14,500 years b.p.). Ice was up to 3000 m thick in central B.C., 2000 m on Vancouver Island Wide-spread glaciation started around 2.5 m.y. ago
