Genesis and evolution of kimberlites
Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

A reappraisal of redox melting in the Earth's mantle as a function of tectonic setting and time
SF Foley - Journal of petrology, 2011 - academic.oup.com
Redox melting refers to any process by which melt is generated by the contact of a rock with
a fluid or melt with a contrasting oxidation state. It was originally applied to melting owing to …
