Spences Bridge Group

From Wikipedia, the free encyclopedia

The Spences Bridge Group is a 100 million year old volcanic group of the southern Intermontane Belt in British Columbia, Canada. It consists of two stratigraphic units known as the Pimainus Formation and the Spius Formation.[1] The Spius Formation represents a shield volcano and the underlying Pimainus Formation is interpreted to be a set of stratovolcanoes.[1]
