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!

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.

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?

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...

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

Today #calcite is on of the competitors in #Mincup24. That's all I need to know: in memory of Ornella I'm in #TeamCalcite, or team #sunstone because of the very high #birefringence of #mineral calcite. First picture is from Ornellas first MineralCup

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!

Calcite is crazy diverse. Just look at this 2015 Smithsonian display of calcite! https://www.mineralcup.org/2023/campaigns/round-1-match-11
