Djibouti

Djibouti

Djibouti occupies the eastern part of the Afar Depression and as such is an integral part of that volcanic-dominated feature, much of which is described under Ethiopia. The 1:500,000 'Geological map of Central and southern Afar' (Varet, 1978) covers the whole of Djibouti and the following localities are all distinguished on that map. The greater proportion of the country is occupied by basalts, mostly tholeiitic, but there are also extensive areas of rhyolite much of which is peralkaline.
