Constraints on volumes and patterns of asthenospheric melt from the space‐time distribution of seamounts

Constraints on volumes and patterns of asthenospheric melt from the space‐time distribution of seamounts

Although partial melt in the asthenosphere is important geodynamically, geophysical constraints on its abundance remain ambiguous. We use a database of seamounts detected using satellite altimetry to constrain the temporal history of erupted asthenospheric melt. We find that intraplate volcanism on...

Zusammenfassung:Although partial melt in the asthenosphere is important geodynamically, geophysical constraints on its abundance remain ambiguous. We use a database of seamounts detected using satellite altimetry to constrain the temporal history of erupted asthenospheric melt. We find that intraplate volcanism on young seafloor (
