The role of gas-fluidisation in the formation of massive volcaniclastic kimberlite

Paper helps people find diamonds. Diamonds are found in large conical geological structures called pipes full of powdery material called kimberlite, within which diamonds are embedded. Paper shows geological structure of pipes is consistent with structures that form in laboratory experiments when gas is passed through a tapered bed of particles so that they are fluidized (i.e. their weight is supported). Work was funded and subsequently used by DeBeers [contact: Independent Consultant (formerly DeBeers Group Geologist Research)]. Work also led to first-author Gernon's PhD and contributed to his appointment as Lecturer at Southampton University [tinyurl.com/gen-eng-47].
