@bkania.bsky.socialLook i just found a new crush this #MinCup26 in #Cylindrite
@erikstrub.bsky.socialCome on! No crystal structure, yes,... but would you also kick out icosahedrite? Probably some people will, but I am all for cylindrical of 5-fold symmetries. Vote #cylindrite ! #mincup27
@ougeolsoc.bsky.social#pyromorphite - dainty green clumps like mineral moss, but the oddness of those "rolled, incommensurate atomic sheets" of #cylindrite is intriguing. Still on #TeamCylindrite in this round of #MinCup26
@bobthebird.bsky.socialNothing else has crystals like these. A vote for uniqueness. #Cylindrite
@crystallised-cricket.comI hope that I'm not the harbinger of doom for #Pyromorphite, but it really does deserve to win today's #MinCup26 round because it does know where it's atoms are at (no crystal structure set for #Cylindrite)
@bowtiediene.bsky.social#MinCup26 I was going to vote for #cylindrite, but then I read about the possible lead remediation properties of #pyromorphite. Go #pyromorphite because lead poisoning freaks me out a bit.
@mineralcup.bsky.social#MinCup26 Round 2 Match 6:
It's a pair of soft, heavy lead minerals as vivid hexagonal phosphate #Pyromorphite is against spiralling rolled sheets of #Cylindrite.

@tarnado.bsky.socialTOXIC TAKIS - VOTE #CYLINDRITE
@ougeolsoc.bsky.socialLove the mica look alike crystals of #pyrrhotite but the sheer strangeness of #cylindrite sheets turning themselves into roll ups is amazing do that's where my bote is going today!

@alexwitze.bsky.socialGotta be #Cylindrite
@beniandermatt.bsky.socialAs someone who doesn't know jack sh*t about minerals, I appreciate #Cylindrite for having a perfectly descriptive name.
A rock that does what it sais on the tin.
@bobthebird.bsky.socialSometimes during #MinCup I learn about a new mineral, and immediately go "I gotta get me one of those!"
I'm voting #Cylindrite
@corgiseveryhour.bsky.socialOh yeah, a #metalmatchup with #pyrrhotite v #cylindrite, and my #teampoison position requires me to pick the lead laden #cylindrite.
@fortmaligator.bsky.socialVoting for #cylindrite tonight as it’s sufficiently convinced me of being a (slightly) better match for Valyrian steel in GOT. Unlike Fe-rich #pyrrhotite, it doesn’t rust; but like Valyrian steel, it’s exceptionally rare. Difficult choice, but visually it’s also spot on for the throne.
@barrygoldman1.bsky.socialfound a paper describing #cylindrite structure a little bit #MinCup26
www.minsocam.org/ammin/AM77/A...
no diagram tho, showing why sheets curl up into cylinders.
@louisedawe.bsky.socialI'm voting #cylindrite for #MinCup26! As reported by Evain in @actacrystb.iucr.org, levyclaudite-(Sb), a member of the cylindrite-type minerals, is incommensurately modulated and joins sheets with mismatched dimensions, producing its extraordinary curved form! journals.iucr.org/b/issues/200...
@warriorchicken.meMy vote goes to #Cylindrite over the fascinating but treacherous pyrrhotite
@crystallised-cricket.comNo contest today in #MinCup26 in my mind - #Cylindrite is one of the minerals that sneaked into definition with no crystal structure defined! So #Pyrrhotite all the way - plus there's there awesome thing that a small nudge in the iron positions is what gives it its magnetic properties.
@mineralcup.bsky.social#MinCup26 Round 1 Match 12
Grey hides complexity for these metal-rich minerals as trickster #Pyrrhotite battles geometrically-unusual #Cylindrite in this monochromatic matchup.
