Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
Jacob and Mikhail 2022, this volume) nor a common crustal mineral (the exceptions being …

Cratons are the ancient cores of continents, characterized by tectonic inactivity, a thick
mantle lithosphere and low heat flow. Although stable as tectonically independent units for …

Zircon megacrysts represent a late stage in the crystallisation of the magmas that produced
the low-Cr megacryst suite (Ol+ Opx+ Cpx+ Gnt+ Ilm+ Phl+ Zir) found in many kimberlites …

Trace element abundances in igneous zircons, as determined by electron microprobe and
laser-ablation microprobe ICPMS analysis, are shown to be sensitive to source rock type …

This remarkable volume presents the first revision to the classification system of diamond-
bearing rocks in over eighty years. Presenting the latest mineralogical data, this book offers …

Although most economic geology research is concentrated at the deposit or mineral-system
scale for a single well-defined deposit group with a consistent metal association, there are …

In this paper the geological occurrence, geochemistry and mineralogy of ultrapotassic
(K2O/Na2O> 3 (molar ratio)) and perpotassic (K2O/Al2O3> 1 (molar ratio)) igneous rocks …

The source mineralogy and conditions of origin of the three main groups of ultrapotassic
rocks are outlined by combining experimental constraints and an abstraction of evidence …

Micro-inclusions in cloudy diamonds from Koffiefontein consist of three main types: silicates,
carbonates and brine inclusions. The silicates belong to either the eclogitic or the peridotitic …

Early recognition and rejection of uneconomic prospects is essential to an economically
rational diamond exploration program. Some powerful new techniques for prospect …
