Summary

Mineragraphic, chemical, and X-ray data are presented on the titanomagnetites1 from a differentiated teschenite sill. The minerals are generally homogeneous. The earliest titanomagnetites are Fe3O4.Fe2TiO4.FeTiO3 a solid solutions; the titanomagnetite crystallization trend is one of enrichment in Fe3O4 and FeTiO3 at the expense of Fe2TiO4. The relations of the titanomagnetites to the parent rocks and associated minerals, and their role in basaltic magma iron enrichment are also discussed.
