Mantle plumes from top to bottom
NH Sleep - Earth-Science Reviews, 2006 - Elsevier
Hotspots include midplate features like Hawaii and on-axis features like Iceland. Mantle
plumes are a well-posed hypothesis for their formation. Starting plume heads provide an …

Rayleigh–Taylor instabilities from hydration and melting propel 'cold plumes' at subduction zones
TV Gerya, DA Yuen - Earth and Planetary Science Letters, 2003 - Elsevier
It is commonly thought that hot diapiric flows prevail in the mantle wedge above the
subducting slab. However, hydration and partial melting along the slab can create a …

Continental crust formation on early Earth controlled by intrusive magmatism
The global geodynamic regime of early Earth, which operated before the onset of plate
tectonics, remains contentious. As geological and geochemical data suggest hotter Archean …
