Mineralogy of High-Ti basalt
Essential minerals - these are minerals that are required within the classification of this rock:
Feldspar > Plagioclase | A petrological term for Albite-Anorthite Series. |
Ilmenite | Fe2+TiO3 |
Pyroxene | A petrological term for Pyroxene Group. |
Non-essential minerals - these minerals are common, sometimes major components, but are not always present:
Armalcolite | (Mg,Fe2+)Ti2O5 |
Olivine | Equivalent to Fayalite-Forsterite Series; usually a more or less Fe-bearing forsterite. |
Pyroxene > Clinopyroxene > Augite | (CaxMgyFez)(Mgy1Fez1)Si2O6 |
Pyroxene > Clinopyroxene > Pigeonite | (CaxMgyFez)(Mgy1Fez1)Si2O6 |
Ulvöspinel | TiFe2O4 |
