Salal Creek Pluton
The Salal Creek Pluton, also called the Salal Creek stock, is a small circular quartz monzonite intrusion with an area of 35 sq mi (91 km2). It is eight million years old, containing 52 dikes composed of basalt and was probably formed 5 mi (8.0 km) or less below the Earth's surface.[1] It forms part of the Pemberton Volcanic Belt, a geological formation that formed as a result of subduction zone magmatism in the Canadian Cascade Arc.
