Delamination introduces warm blocks of lower with a low melting point into mantle; these eventually heat up, ascend, decompress, melt. The mantle below 100 km depth is mainly dry peridotite, but its temperature will be above recycled fertile (basaltic or eclogitic) components, obviating need excess form "hotspots" "melting anomalies". plates pull apart delaminate, upwells; entrained crustal fragments various ages are create anomalies along developing mid-ocean ridges, fracture zones, old suture zones. Eclogites associated delamination warmer less than subducted oceanic more susceptible entrainment. You do not have access content, please speak institutional administrator if you feel should access.
