5203 |a"Quaternary intermediate volcanic rocks of the Monmouth Creek volcanic complex, located west of Squamish, British Columbia, were mapped to determine their extent and origin. The deposits are distributed within a deep embayment in the granite wall of the Howe Sound, and have a present day thickness of about 200 m. They comprise a sequence of andesite lavas, domes, and lobes, and associated monolithological andesitic breccia units. Cogenetic, en echelon andesite dykes intrude the entire complex, and their erosional remnants outcrop as a series of steep-sided, enigmatic pinnacles and spires. On the basis of petrographic and geochemical criteria the authors identify two distinct magma types expressed as aphyric andesite and hornblende andesite. On the basis of field relationships and the properties of the volcanic deposits and their distributions, the Monmouth Creek volcanic complex is shown to have a glaciovolcanic origin. A model is presented for the emplacement of the volcanic deposit that indicates the presence of a major fjord-filling glacier, likely greater than 1 km thick and occupying Howe Sound to an elevation of about 800 m above present-day sea level at the time of eruption"--p. 1.
