The asthenospheric magma may interact with the overlying lithospheric mantle.
The available data suggest that the source of these rocks was a fertile, garnet-bearing, asthenospheric mantle.
The magmas have clearly remained in the upper mantle since the oceanic lithosphere was formed, and have not been displaced by asthenospheric flow since that time.
These Quaternary volcanic rocks from Santorini are Cenozoic volcanic rocks with a significant asthenospheric component.
