The development of magmatism along the Cameroon Volcanic Line: evidence from seismicity and seismic anisotropy [PDF]

, 2014
The Cameroon Volcanic Line (CVL) straddles the continent-ocean boundary in West Africa but exhibits no clear age progression. This renders it difficult to explain by traditional plume/plate motion hypotheses; thus, there remains no consensus on the ...
