Abstract
The principal objective of this chapter is to compare, contrast, and illustrate the mineralogy and petrology of archetypal kimberlites, also known as group I kimberlites, with those of the group of diamond-bearing rocks which, in this work, are termed “orangeites.” The latter rocks have previously been termed “micaceous kimberlites” or “group II kimberlites.” The discussion, in conjunction with detailed mineralogical studies described in Chapter 2, will demonstrate conclusively that kimberlites and orangeites cannot be derived from the same parental magma and thus are not genetically related.
Working towards precision in nomenclatural problems is not simply play for bureaucratic minds but, on the contrary, it is a suitable exercise which should lead to less ambiguous communication. Gian Gaspare Zuffa (1991)
