Pyroclastic volcanism of Middle Miocene age in the Valle del Cura: New geological and radiometric data

Recent studies of the geology and volcanic stratigraphy of the Valle del Cura, plus a new radiometric age, led to the recognition of a pyroclastic event of Middle Miocene age that completes the Tertiary volcanic stratigraphy of the region. These rocks are represented by dacitic crystalline tuffs int...
