Summary:
Tentative name "Berlin volcanics" used by Felts (1936, unpub. thesis) is abandoned in favor of Mehama volcanics which occurs in northwestern Oregon. Felts (1936) described "Berlin volcanics" as varicolored volcanic rocks in southeastern quarter of Lebanon 15' quad, OR, as showing "such lack of sorting, rounding, or bedding that they must be classed as air-laid volcanic breccias". Age of Mehama volcanics is Oligocene, although lower part may range downward into Eocene.
