- •
The northern Afar Depression is one of the most volcano-tectonically active portions of the East African Rift system.
- •
Quaternary lavas in this area range from transitional to tholeiitic basalts, with significant across-axis variation.
- •
Depth and degree of melting of the source reservoir underneath the rift played a major role for the geochemical variations.
