| 11. | The lithosphere is only 30 km and there is a low seismic velocity asthenosphere below.
|
| 12. | As delamination continues, more asthenosphere rises to replace the lower lithosphere as it sinks.
|
| 13. | A steepening of the subduction after 12 mya resulted in the influx of hot asthenosphere.
|
| 14. | Beneath the northern margin of the plateau, anomalies in the asthenosphere have been described.
|
| 15. | The weakness of the asthenosphere allows the tectonic plates to move easily towards a subduction zone.
|
| 16. | The geothermal structure in a subduction zone determines the melting rate of subduction slab and asthenosphere.
|
| 17. | Several explanations have been proposed : a lower limit to the pliable asthenosphere, a phase transition,
|
| 18. | This would suggest that the Lithosphere-Asthenosphere boundary underneath oceanic lithosphere also deepens with plate age.
|
| 19. | The lithosphere essentially " floats " on the asthenosphere and is broken-up into ten major plates.
|
| 20. | The calculated source depth of the lava is consistent with an origin at this depth in the asthenosphere.
