Rhodochrosite has won the Mineral Cup!
Well done @mineralcup.bsky.social and congratulations to the meat rock fans! #MinCup24 was a great success as always.
Here’s my final excuse to post my Lino block print Rhodochrosite.
Next year I have a different print to suggest. 😉

Ihr Wisst, was ihr zu tun habt: stimmt für Kyanit!

Repost from Adriana Guatame
(@adriguatame.bsky.social):
With #kyanite I always remember this video created by Stacey Phillips via the Mineralogical Society (the LEGO stop motion science videos) -
All my faves have been defeated so here’s your chance to convince me to vote in the finals of #MinCup24!
Shall it be Rhodochrosite so we never have to hear the chants of “meat rock” again?
Or should I vote for pretty blue Kyanite, used in ceramics, gems & as an index mineral?
Convince me.

Some non #MinCup24 related mineralogy.
The discussions around calcite made me think of the database of grains in sediment from my 2023 paper (https://www.nature.com/articles/s41598-023-47029-4).
There is this thing we tell: aragonite is more common in the #ocean in low latitudes than in high latitudes. But I can show that with my #research !
I reprocessed the data for the shelves to show how carbonate grain mineralogy changes with latitude - for the #sedimentology classroom. -

It's the #MinCup24 finals! There were ups and downs, but my favorite Rhodochrosite has made it to the finals! Please vote for this lovely pink mineral that has inspired many legends 😊

We made to the final round of #MinCup24, it's the moment - Red vs. Blue!
Rhodochrosite, a flamboyant carbonate and possibly a key to the Mn cycle up agians Kyanite, a bladed aluminosilicate. While we still want revenge for Calcite, it's Go #TeamCarboante!

Alright fine. I guess we're doing red vs blue (someone who paid more attention to RvB than me should haul out the quotes.) (... well okay it's more that I've never seen the first like. Idk 5 seasons? With captions so I genuinely dgaf. I have an autograph from... someone roosterteeth circa 2010 tho), so ANYWAY tangent aside, while the meat rock looks tasty, you can't eat it. So one must go with #kyanite!! #MinCup24

Kyanite is used in porcelain(more dishware and plumbing than art) but it is used in jewelry. Plus it is an index mineral. But I am going to give the art vote to Dioptase for its unparalleled history as a pigment which stretches back to the Neolithic! For the #MinCup24 semi-finals and the last surviving pigment in competition!

Perovskite is found just west of Montreal in the Oka Complex; Carbonate-rich, silica-poor magma emplaced in the Cretaceous. The site was mined for niobium in the 1960's and 1970's -it's also enriched in REEs and thorium.
There’s more about perovsite at Oka on MinDat:

Today's the day! Vote Rhodochrosite! It is beautiful, and it is attached to some gorgeous legends. It looks like petrified roses. Rose Garden of the Dwarven Kingdoms. ❤️

Pretty blue Kyanite is used in porcelain(though more dishware/plumbing than art) but it is used in jewelry. Points for physics as an index mineral.
But topaz wins the art vote with centuries of gems, carving & jewelry. Plus on the physics front we have its use in lens & xray spectroscopy #MinCup24

Kyanite isn't just a fetching blue mineral that documents the experience of sediments under extreme duress.
It's an ore -Virginia alone mined 83,000 tonnes in 2023. Kyanite in furnace insulation transforms to mullite when heated, expanding to reduce porosity and shrinkage.Virginia Kyanite (photo: J. Wyman) from:

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. -
As of this round of the #mincup24 vote, I chose #Dioptase over #Wavellite since I own more specimens (obviously, I bought more because I loved it more, for the emerald color and its variety of localities). :blobcatgooglytrash:

Vote for #Dioptase in this year's #MinCup24 🍀 Now and the next round to come! As said last year as well, dioptase can be stunning. (And I expected the preview to show my pics from last year?)

O no what a match-up. Alas for #wavellite, lovely kiwi mineral, arbitrary choice to vote for the one in my collection has me voting for #dioptase. (I think this might be the furthest in dioptase has gotten in the years I've been playing! 👀 ... now watch I just jinxed it. 😆) #MinCup24

Antimony Tin Oxide scatters the wavelengths of infrared light emitted by warm humans. The antimony is often sourced from #stibnite. This material is being used to create fabric infrared invisibility cloaks!

Round 3 Match 1 of #MinCup24 is a challenge for my art or physics voting scheme!
Perovskite wins the physics vote with its exciting possible origins in the mantle or even a Brown dwarf + its potential for use in solar panels
Stibnite wins the art vote for kohl, glassmaking & pyrotechnics & as a grey-black pigment for centuries
-
Pretty purple Charoite can be carved but I have to give topaz the art vote for jewelry since ancient times.
Topaz also gets the physics vote for its use in optics and x-ray spectroscopy.

Please vote for the beautiful, purple #Charoite in today's #MinCup24. Slightly radioactive ☢️ & weakly fluorescent, and so 'Deep Purple' people first thought it was dyed, we have a pretty unreal 'metal' 🤘 pick to beat boring yellow-brownish topaz. Charoite needs your help!

yeah calcite is cool but have you considered a mineral that is not literally the most common one on earth #titanite #teamTitanite #mincup24
RE: https://bsky.app/profile/did:plc:r6drdfmf5fzdtvuacnfmfiga/post/3l4sde3scbl2e -
Vote calcite for its gargantuan role in art history: all of marble & limestone sculpture, chalk drawing, large amounts of painting as pigment & extender. Vote calcite for fossils! And trilobite eyes!
Sure titanite gets points as an indicator mineral but birefringent calcite gets the physics vote!
