AUSTRALIA and beyond - We need to assemble again for #Putnisite! This amazing structure needs your support in today's #MinCup26 battle. For shear density and novelty in its strange/wonderful crystal structure it should get your vote over #Julienite
Image representing the crystal structure of putnisite - here red spheres represent oxygen atoms, light blue spheres/polygons represent calcium atoms, dark blue spheres/polygons represent silicon atoms, brown spheres/polygons represent carbon atoms, green spheres/polygons represent strontium atoms. There is also some chromium hiding in the structure that is in part represented by a yellow triangle. The representation is drawn in VESTA from entry #20044 in the American mineralogist database
Image representing the crystal structure of julienite - here red spheres represent oxygen atoms, dark yellow spheres/polygons represent sodium atoms, dark blue spheres/polygons represent cobalt atoms, yellow spheres represent sulfur atoms, brown spheres represent carbon atoms and light blue spheres represent nitrogen atoms. The structure is viewed down its c axis and shows that there are sodium/water(oxygen) units surrounded by cobalt complexes with nitrogen, carbon and sulfur attached. The representation is drawn in VESTA from entry #9760 in the American mineralogist database

#MinCup26 Round 2 Match 5 It's a pair or rare, vibrant minerals with unusual chemistry as purple #Putnisite is up against blue #Julienite. VOTE: www.mineralcup.org/2026/vote-re... RESULTS: www.mineralcup.org/2026/vote-re...
Split photo of tiny grape-jello purple cubical crystals with a rough surface. The crystals are poking out of a massive rough rock with areas of fuzzy green and broad purple, all with a grainy coating of white as though it were rubbed with flour. The other photo is saturated cobalt blue needle-line crystals in a narrow fan sparkly and rough on a smooth creamy background

Attracted by the backstory for #julienite (and as Henri Julien was french, presumably the name is pronounced with a soft "J" ?) So, vote #teamjulienite in #Mincup26

Voting #Julienite for #MinCup26! Check out this classic @actacrystb.iucr.org by Cano et al. to see a different cobalt(II) thiocyanate, this one with Co-NCS-Co bridges, and with water molecules and sulfur completing a hydrogen-bond network. journals.iucr.org/paper?S….

Today it's #Calcite against the extremely rare #mineral #Julienite at #MinCup26😻 We vote for calcite in memory of Ornella 🌈 who voted for calcite because of its use as #compass 😻 due to its high birefringence😻
Ornella 🌈 is showing her compass

#MinCup26 Round 1 Match 11 It's a pair of minerals that pull off near-magical tricks with their properties as ubiquitous #Calcite is up against rarity #Julienite. VOTE: www.mineralcup.org/2026/vote-re... RESULTS: www.mineralcup.org/2026/vote-re...

Going with #Julienite this round, because I was a grad student, and I now teach grad students on a regular basis so the name of this one hit me right in the feels, y'all. (I'd like to be hard scientific about this stuff but I'm a sociologist. I'm all about the people behind the science.) #MinCup26
