New age tor the vitrophyric rhyolite-dacite from Ancud (42°S), Chiloe, Chile

Charles R. Stern    
Mario Vergara    

Resumen

Vergara and Munizaga (1974) reported an age of 760,000 years for a sample of rhyolite-dacite obsidian from the mainly late Oligocene to Miocene Central Valley volcanic belt at Ancud, Chiloe (Fig. 1). They interpreted this sample as representing ?a last and isolated volcanic event in this series?.
