Ugh, those brackets this year are miserable! I tend to support #teamClay but facing off against metal? Btw, both sound like people from other planets in a very goofy scifi series. I need to read more arguments first.

Come on #TeamClay go vote for #nontronite
#MinCup25 Round 1 Match 15 - It's a mineral found mostly in the farthest reaches of space vs one so common an exhaustive list of localities is nigh impossible as alloy #taenite faces off against clay #nontronite.

Obvs I'm backing Lizardite and sepiolite 'cos I'm team clay 4 lyfe. But interesting to see vivianite, aka the missing mineral, back in the running with Fluorapatite, the very not missing mineral. Phosphates are phos-GREAT! #MineralCup #TeamClay

Kaolinite preserved this fossil for over a billion years, and forms the mug I'm drinking coffee from. Zircons cool but TMK can't preserve fossils, and has never held my beverages. #ClaysForDays #TeamClay #geology ⚒️ fossil is 300 microns long.

Totally supporting #TeamCopper this year, even though it's not doing brilliantly. But then again, I used to support #TeamClay, and look what happens every year.

Like every year I'm on summer vacation and will try not to forget #Mincup next to all the great things around me. Not sure yet whom to root for, but as ever I'm totally #teamClay

I'm a hydrologist at heart, I was ecstatic. (And soil science slightly lower down, so still upset at #TeamClay never getting a look in)

Another highlight is this VHS recording of the American Idol finale? Justin vs Kelly or Clay vs. Reuben? I'll never know! #teamclay
