Abstract
IGNIMBRITES are commonly of rhyolite, rhyodacite or dacite composition, less commonly of andesite composition, and rarely of basalt composition. Ignimbrites associated with sodic-alkaline volcanism are rare and known examples are restricted to the Kenya field, although doubt has been cast1–3 on their ignimbrite origin4, and it has been suggested that they are more akin to froth flows. A preliminary examination of a series of rocks from Tenerife indicates that in this, another sodic-alkaline environment, a number of different types of volcanoclastic flow may be distinguished.
