ulvöspineln.

/ˌʌlvəʊspɪˈnɛl/

Forms: Also ulvospinel.

Etymology: < Swedish ulvöspinell (F. Mogensen 1943, in Blad för Bergshandt. Vänner XXVI. 135), < the name of the Ulvö islands, Sweden: see spinel n.

Mineralogy.

A mineral of the spinel group, Fe₂TiO₄, frequently found as lamellæ in magnetite.

1947 Mineral. Abstr. X. 6 X-ray examination shows two spinel phases with cell edges 8·40 and 8·47Å., close to the values for magnetite (8·37) and ferrous orthotitanate Fe₂TiO₄ or titanspinel (8·50). It is assumed that the ore contains a large amount (100,000 tons) of the latter which is named Ulvöspinel.

1963 D. W. Humphries & E. E. Humphries tr. H. Termier & G. Termier Erosion & Sedimentation i. 6 The Curie point is 575°C. for pure magnetite and 675°C. for hematite; it alters in the solid solutions of magnetite (Fe₃O₄) and ulvo-spinel.

1970 Sci. Jrnl. May 32/3 If the lava lake was sufficiently enriched in titanium dioxide, its base would tend to collect concentrations of ilmenite, ulvospinel and pseudobrookite.

1971 Nature 3 Dec. 264/1 The rock contains relatively small amounts of the phases that we have found in other Apollo basalts (nickleliferous iron, troilite ulvöspinel, ilmenite, [etc.]).
