| The Ambre-Bobaomby volcanic field at the northern tip of Madagascar consists of Miocene volcanics capped by very recent cones. The earliest volcanism produced a large basaltic massif and minor pyroclastic flows. Tertiary to Quaternary volcanic rocks span a wide geochemical spectrum, including basaltic, andesitic, rhyolitic, trachytic, phonolitic, and foiditic compositions. The young volcanoes have very well-preserved morphologies and were mapped as Recent (Besairie, 1973). Other very recent cones are located at the southern end of the massif, and crater lakes are also present. | |||
