Lapili tuff & volcanic breccia
Virtual Museum ID: 20-S23-34
These deposits were formed when airborne debris from nearby volcanic eruptions was deposited over a wide area. The red and maroon colours indicate a subaerial rather than a submarine environment.
These rocks are believed to be mainly early Jurassic in age deposited during the Sinemurian time period. Further east in McKendrick Pass and Saturday Lake areas a thick polymictic basal conglomerate separates these rocks from older late Triassic volcanic rocks of the Takla Group.
