BackgroundThe Mega Basalt field, straddling the Ethiopia-Kenya border, is referred to in Kenya as the Dukana volcanic field. The Ethiopian portion was considered to have been active during the Holocene (Mohr, 1979; Davidson, 1983). The Kenyan portion was mapped as Pleistocene in age, with one Potassium-Argon date of about 0.9 million years ago (Charsely, 1987). The 1.8-km-wide Gof Dukana basaltic maar is surrounded by ejecta containing abundant basement igneous and metamorphic rocks. About 50 pyroclastic cones with associated lava flows rise to about 150 m above the lava platform in northern Kenya.
