Kimberlites

Developments in Petrology, 11B: Kimberlites, II: The Mantle and Crust-Mantle Relationships focuses on the formation, characteristics, and properties of kimberlites.
The selection first offers information on silicate and oxide inclusions in diamonds and diamond eclogite and graphite eclogite xenoliths from Orapa, Botswana. The text also ponders on petrography, petrology, and geochemistry of xenoliths and megacrysts from the Geronimo Volcanic Field in Arizona and two-pyroxene megacrysts from South African kimberlites.
The text elaborates on the nature of the upper-most mantle beneath Victoria, Australia as deduced from ultramafic xenoliths and depleted mantle rocks and metasomatically altered peridotite inclusions in tertiary basalts from the Hessian Depression. Topics include area and rocks of investigation, composition, abundance, and properties of metasomatically altered mantle, and petrography and mineralogy.
The selection is a dependable source of information for readers interested in the formation, properties, and characteristics of kimberlites.
