Introduction:
Nosy-Be island off the NW coast of Madagascar contains very recent basaltic lava flows from well-preserved cinder cones. Many large crater lakes are found in the central part of the island. Nosy-Be volcanics, which are dominantly of low-silica foiditic compositions, overlie Mesozoic limestones and other sedimentary rocks. Two periods of activity occurred at Nosy-Be. Initial eruptions of fluid lava flows from the western side of the massif were followed by the construction of numerous strombolian cinder cones on the western plain. Little is known about the age of the volcanic field, and the only K-Ar dates are Tertiary in age, but the Nosy-Be volcanics were mapped as Recent (Besairie, 1973).---
