A systematic study of the Raman spectra of the titanomagnetite solid-solution series (Fe 3-x Ti x O 4 ) for x = ~0.0, 0.2, 0.4, and 0.6 has been conducted. The samples showed combinations of five previously predicted Raman peaks at ~190, 310, 460, 540, and 670 cm -1  that correspond to vibrational modes with T 2g (1), E g , T 2g (3), T 2g (2), and A 1g , respectively. The calibration of Raman spectra for titanomagnetite with known values of Ti concentrations reveals a strong dependence of relative intensity for the T 2g (2) and T 2g (3) modes on Ti concentration. The most prominent feature is the appearance and increase in the relative intensity of a T 2g (3) peak above x = ~0.2. On the other hand, the Raman peak for the T 2g (2) mode gradually diminishes as Ti increases and nearly disappears at x = ~0.6. Combining the two relative intensities potentially provides a sensitive indicator of Ti content. The technique was applied to study titanomagnetite in grains from Hana Volcanics and melatroctolite from Rhode Island.
