Description
-
Diagram showing the three types of mantle plumes. The Austral-Cook volcanic chain is sourced from the superplume shown under the Pacific Ocean. These plumes are broad and tend to stall in the upper mantle. There, they spawn into a series of smaller heterogeneous plumes, which are the expressions we see at the surface.
