One possible source of these structures is dense thermochemical piles overlying ultra-low velocity zones.
One possible source of these structures is dense thermochemical piles overlying ultra-low velocity zones.Campbell and Griffith showed that komatiite was probably formed due to these structures. The largepositive Clapeyron slope of the post-perovskite transition has a significant impact on their formation. HansRamberg pioneered the use of large-scale models to study these structures. W. J. Morgan was the firstperson to propose the existence of these structures. They consist of a hot tail and a cooler head. Thesestructures explain giant oceanic plateaus, large igneous provinces, continental flood basalts, and hotspotvolcanism. For 10 points, identify these columnar upwellings in the mantle.
