The Tuscan Formation of Northern California With a Discussion Concerning the Origin of Volcanic Breccias
Anderson CA. 1933. The Tuscan Formation of Northern California With a Discussion Concerning the Origin of Volcanic Breccias. Bulletin of the Department of Geological Sciences. 23(No. 7):215-276
The Tuscan formation appears at the southern end of the volcanic province commonly referred to as the Cascade Range, while older rocks to the east are part of the Sierra Nevada. To the west, the volcanic Tuscan formation interdigitiates with the Tehama formation which forms a part of the Coast Range. Volcanic breccias resulting without water in addition to those transported by water are also discussed. Lassen Peak in particular is mentioned with relation to mud flows formed by nuie ardente eruptions, where melted snow banks caused a torrent of mud.
