,The Sub-Continental Mantle and Crust — Evidence from Kimberlite Xenoliths,orhombic olivine to its denser, cubic polymorphringwoodite. The fact that ringwoodite has not yet been identified in the kimberlites gives a maximum value of 300 km to the depth sampled by kimberlite.

0343-2181 that it is getting something worth reading. After all, intense research into the upper mantle over the past two decades has already resulted in a number of volumes on kim berlites and their xenoliths. So why yet another one? First, in this book I have concentrated on kimberlite as an individual roc

Distribution and Tectonic Setting of Kimberlites,ork. In addition, it is apparent that in many areas, and particularly in the circum-cratonic fold-belts, the intrusion of kimberlite is part of a phase of very limited igneous activity manifested by intrusion of other rare rock-types; brief summaries of this contemporary activity are included below.

Mineralogy of Kimberlites, incorporated from the high-level formations forming the wall rocks of the kimberlite intrusions, and (b) later minerals formed during weathering or percolation of groundwater, it will be appreciated that the mineralogy of individual kimberlites may be extremely variable and complex.

Kimberlite Genesis, it will be seen that the essential problem is the origin of the phenocrysts and the kimberlite matrix itself. In particular, it is the source and reasons for the concentration within the kimberlite matrix of the high amounts of incompatible elements (see Chap. 5, kimberlite geochemistry) that have to be explained.
