    This chapter is divided into three sub-sections covering xenoliths types, distribution and transport; xenoliths and megacrysts of mantle origin; and xenoliths of crustal origin. The first section provides a review of xenolith and megacryst distribution, nomenclature and discusses ascent mechanisms and rates. Section two covers macroscopic features, texture and microstructures of mantle xenoliths. Other topics in the section are composite xenoliths, mineral assemblages and geochemistry and petrographic and geochemical evidence for mantle metasomatism within the xenoliths. Section three covers the occurrence, mineral assemblages, microstructures and geochemistry of crustal xenoliths. Isotopic characteristics are briefly mentioned. -R.W.Nesbitt
