  1. Look at this #calcite crystal and its super strong birefringence, yielding two distinct optical paths! And yes, that's Captain Haddock, a subtle reference to the strong polarization effects in calcite sunstones, likely used as navigational aid by seafarers in the Viking Age. #MinCup25 #teamcalcite

  2. Now for a match-up I actually care about in #MinCup25 ! I feared this.
    Perovskite is such a potentially important part of our #solarpunk future... but I'm #TeamCalcite through, so there was never really a choice.

  3. It's not that I don't like Rhodochrosite; I do. But people, don't let that distract you from the goal tonight - a win for Calcite in this round of #MinCup24. For the foraminifera, for the red algae, for the sea urchins - do it for the urchins!

  4. A faithful and painful day in #MinCup24 - the battle of the carbonates: Rhodochrosite vs. Calcite.

    One is a sink for calcium, the other for manganese. Both are cool, both are important, but only one of them is a major skeleton-forming mineral.
    So it's #TeamCalcite today, but it will be #TeamCarbonate later.

  5. People, what is wrong with you?
    Why choose a mineral that comes in only one color when you can have a mineral that can come in all colors?

  6. One of the things I really like about Calcite is how weird it is. You see, Calcite can have a variable amount of Mg in it, and that amount varies by rate, but also what else is around, which could lead to some other interactions...

  7. Time for #TeamCalcite to once again bring in the votes as our home team is up against Titanite on #MinCup24.

  8. @FaithfullJohn This is #TeamCalcite land, we have signes and secreat handshakes and everything.

  9. Todays the day! The most important matchup of #MinCup24 - Calcite vs. Celestine ⚒️
    I like Celestine; it's really important in the story of Aragonite diagenesis; I want to do more with it.
    It's a nice dash of blue - but Calcite is the medium!
