Cognate Mineralogy,pter is therefore to identify both unusual mineral species and compositional fields of common minerals which are characteristic either of lamprophyres collectively, or of particular branches.

Nature, Origin and Evolution of Lamprophyre Melts, (1986) and Bergman (1987). This chapter concentrates on: (1) the nature of lamprophyre liquids; (2) genetic unity and diversity; (3) the probability that lamprophyres represent . melts (Appendix B), or parent melts to a range of more evolved (intermediate-felsic) rock-types.

Economic Geology,nting evidence that lamprophyres are connected with a medley of precious materials: diamond, gold, sapphire and possibly PGEs. A realization has dawned that lamprophyres are ‘ultra-deep’ (Section 8.3), and that this makes them economically special. Even confining attention to lamprophyres . kimberli
