Abstract
The trends of heat flow density in West Africa are discussed in relation to the large-scale structural framework. The heat flow density is low in the stable Archean nuclei (30–40 mW m−2) and increases to 50–60 mW m−2 in the surrounding mobile belts affected by the Pan-African orogeny (600 Ma). In the northern part of West Africa, the high heat flow density (70–100mW m−2) is interpreted as resulting from a rejuvenation of the lithosphere during Mesozoic and Cenozoic in connection with several tectonic processes (Hercynian orogeny, Cretaceous rifting, Cenozoic volcanism and Alpine orogeny).
