In today's #MinCup26 duell it is #Hafnon against #Putnisite we didn't know either of them, but we see that the #mineral Hafnon has a simple formula Hf[SiO4]. Just simple enough for our humans😽 and that it is the only known mineral with #Hafnium as main ingredient🙀 #DoesItCat ? Yes🐾

#MinCup26 Round 1 Match 9: It’s a pair of tiny minerals with unusual chemistry as hafnium-containing #Hafnon battles with strontium/chromium-containing #Putnisite. VOTE: www.mineralcup.org/2026/vote-re... RESULTS: www.mineralcup.org/2026/vote-re...

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

#MinCup26 Minerals as #Transformers Small brown and craggy #Hafnon bears a resemblence to Tasmania Kid, while #Putnisite is giving me Misfire vibes.
Cartoon drawing of the transformer called Tasmania Kid who turns into a brown tasmanian Devil. he's a bit craggy.

I'm afraid the bling factor of both minerals in todays #MinCup26 does nothing for me at all. However #Hafnon gets my vote for the super sluthing story of how this minerals main constituent #Hafnium was discovered. Have a read of this www.ch.ic.ac.uk/rzepa/blo…. @mineralcup.bsky.social

Hafnium and Niels Bohr - Henry Rzepa's Blog

In 1923, Coster and von Hevesy claimed discovery of the element Hafnium, atomic number 72 (latin Hafnia, meaning Copenhagen, where the authors worked) on the basis of six lines in its X-ray spectrum. ...

I have to go with #Hafnon in this round because as beautiful as Putnisite is, I'm unfortunately not that great at staying hydrated. But I am definitely resilient and irregular on a daily basis. #MinCup26

I am a sucker for minerals with less common elements. The last time I thought about hafnium was probably in 1988! But now again today. Vote #hafnon! #MinCup26

Somebody persuade me which of these very esoteric minerals to vote for please! #Hafnon, pretending to be zircon in pegmatites, or pretty purple volcanic #putnisite? #MinCup26

Please vote for #Hafnon for its contributions to geochronology. Thank you for your time and help. ( If you ❤️ Zircon, you surely ❤️ its good friend Hafnon. 🙂)

Putnisite is stunning but my vote tonight goes to #hafnon for its extreme temp performance & aerospace applications 🚀 (Also, it doesn’t sound like ‘Putin.’)
