The plateau effectively capped the plume for 30 million years, suppressing mantle melting, halting the creation of new volcanic structures, and resulting in the 30-million-year gap in the Samoan ...

The mantle is split up into two domains — the African and the Pacific — that emerged when supercontinent Pangaea broke apart. When you purchase through links on our site, we may earn an ...
