  abstract = {{G}em corundum, a minor but persistent megacryst in east {A}ustralian basalt fields, is mined from some placer concentrations. {L}aser ablation, inductively coupled plasma mass spectrometry analyses and {O} isotope determinations on a colour range of corundum from different fields, show that chromophore ({F}e, {C}r, {T}i, {V}) and genetic indicator ({G}a, {M}g, 18{O}) values can distinguish corundum sources (magmatic, metamorphic and metasomatic) before basalt incorporation. {T}hey also characterise corundum groups from different fields. {T}his identified two metamorphic groups, one carrying ruby at {B}arrington {T}ops, and a magmatic group distinct from those from other gem fields (lower {F}e, northeast {T}asmania; higher {F}e, {Y}arrowitch). {R}uby-bearing groups show clear provincial characteristics and include lower temperature spinel-facies groups ({B}arrington, {Y}arrowitch) and higher temperature garnet-facies groups ({C}udgegong-{M}acquarie {R}iver). {H}igh {M}g/{F}e and {N}i values in the latter approach those for corundum in diamond, and are a possible diamond indicator. {T}he corundum derived from diverse fold-belt and felsic sources in underlying lithosphere forms a dataset for comparing corundum from other basalt fields.},
