Pebble Creek Formation
From Wikipedia, the free encyclopedia
Pebble Creek Formation is a volcanic formation in the Garibaldi Volcanic Belt created when Mount Meager erupted about 2,350 years ago and by two rock avalanche deposits.[1]
The two rock avalanches are not linked with the 2,350 BP eruption, although the post-eruption avalanche may have its causes in the over-steepened slopes produced by the explosive period of the eruption.[1]
The rocks of the Pebble Creek Formation are the youngest known of the Mount Meager volcanic complex, and are made of dacite.[1]
The formation includes a dacite lava flow, pyroclastic flows, lahars and fallout pumice.[1]
