This book presents topical research in the study of the mineralogy of zircon and olivine and their properties, production and applications. Topics discussed include the application of U-PB dating and chemistry of zircon in the continental crust of Calabria; the internal morphology and crystal growth of accessory zircon from igneous rocks; the reduction, softening and melting behaviour of olivine pellets in an experimental blast furnace; characterizing the radiation damage in zircon and the weathering reactions of olivine as an effective way to sustainably capture CO2.
