"This monograph, written by three experts with long experience in the field, presents a complete account of the characteristics of komatiites including their volcanic structures, textures, mineralogy and chemical compositions. Models for their formation and eruption are evaluated, including discussion of the controversial issue of whether komatiites originate from anhydrous or hydrous magmas. Stephen Barnes and Michael Lesher have contributed one chapter on volcanology and another on the valuable nickel and copper ore deposits found in some komatiites." "Komatiite is a key reference for researchers and advanced students interested in petrology, Archaean geology, economic geology, and broader questions about the evolution of the Earth's crust and mantle."--Jacket.
