  1. #MinCup24

    ⚒️🧪 geology

    Congratulations, #calcite! Your fizzy effervescence makes us bubble with joy. Farewell #titanite. Your chronology indicates a return in 2025.

  2. Just sayin’ the margin is currently 2 VOTES between #Titanite and #Calcite if you want to recruit new players to your #MinCup24 team.

  3. 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.

  4. 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.

  5. #MinCup24 R2M7: #Titanite versus #Calcite

    This matchup is all about timing.

    Titanite's main claim to fame is as an indicator mineral for everything from formation temperature, pressure and chronology. Calcite’s U-Pb dating can help constrain the timing of fault slip, and the minimum age of ancient ocean crusts and volcanic rocks

    Time to choose a mineral!

  6. 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.

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