loveringite
Loveringite is a rare metallic oxide mineral of the crichtonite group with the chemical formula (Ca,Ce)(Ti,Fe,Cr,Mg)21O38. It is a late-stage magmatic mineral, formed in the residual melt of mafic layered intrusions in either the olivine-chromite, pyroxene, or plagioclase-rich layers.〔(Handbook of Mineralogy )〕
==Discovery and occurrence==
Loveringite was discovered in 1978 in the Jimberlana Intrusion, Dundas Shire, Western Australia,〔(Mindat with locations )〕 and was named for Australian geochemist and University of Melbourne professor John Francis Lovering, in recognition of his work on fission-track methods in geochemistry.〔〔
Loveringite has also been generally found in areas of medium-grade metamorphism, reported from the Hoggar Mountains of Algeria; the
Hohe Tauern Mountains, Salzburg, Austria; the Koitelainen intrusion of Lappland, Finland; Bourg d’Oisans, Isere, France; Bracco, Liguria, Italy; the Kerguelen Islands; the Khibiny Massif in the Kola Peninsula of Russia;〔〔 and at Makwiro on the Great Dyke in Zimbabwe.
