  1. Titanite encircling illmenite in an amphibolite-facies metabasalt.

  2. Repost from last year: A titanite lozenge imaged both using a cellphone through the microscope ocular, and with a proper imaging system. It's surrounded mostly by quartz (+feldspar).
    Likely from the Grenville, but from a teaching collection two generations of retired professors ago.

    Titanite can be part of the record of temperature, pressure, and timing of crystallization.

  3. Reposted from bsky:
    A hand-ground section of tephrite from Kaiserstuhl Volcanic Complex showing

  4. Repost from last year:
    I've seen sphene! (Sounds better than "the rock is tippsy with titanite")

    Centimeter-size black sphene (titanite) with apatite (dark brown) and orthoclase feldspar (light brown). Folding pocket knife for scale.

    From the Bancroft locality in Ontario, Canada. Grenville-aged (~1.2± billion years)

  5. from the Rocky Mountain Association of Geologists:
    Titanite: the Wedge-shaped Timepiece, by Ronald L. Parker

    has a distinctive crystal form that it flaunts…

    …titanite is among the very few minerals that enjoy a larger color dispersion than that of diamond…

    Hayden, Watson & Wark established that the relative concentration of Zr 4+ in titanite is systematically related to pressure and temperature conditions.

  7. Next round in #mincup24 : it's #titanite vs. #Calcite . I voted for titanite because I love the Hauzenberg area where it was first found. And I love the colours.

  8. I've seen sphene! (Sounds better than "the rock is tight with titanite")

    Centimeter-size black sphene (titanite) with apatite (dark brown) and orthoclase feldspar (light brown). Folding pocket knife for scale.
