Logging on for the first time in forever to share exciting work done by my husband and his colleagues. 18 million year old enamel proteins from the Turkana Basin, Kenya.
I didn’t have anything to do with it, but it’s very cool.

@cbdawson the chaos makes it more fun 😄
@cbdawson it’s also worth noting that I also like messing with my husband who is one of those people who are adamant that mercury isn’t a mineral 😂
@cbdawson it’s funny to see people get big mad about it as if it’s the big issue geology should working on, instead of just shrugging it off as a exception to the rule and moving on 😂. And the definition of mineral doesn’t specify a temperature range anyway, so I don’t see a problem just going with it. It’s not that big a deal. And maybe it’s because we’ve had this fight so many times over ice so all I can do now is laugh
Today’s matchup between calcite and mercury is a difficult one for me. Not because I can’t choose which is my favorite (I love calcite), but because there a part of me that just wants to vote for mercury because it upsets so many people that mercury is on a mineral list 😈 #MinCup23 https://www.mineralcup.org/2023/campaigns/campaigns/campaigns/round-2-match-5
Vote in Round 2 Match 5 — Mineral Cup
It’s a legendary pair of minerals with a unique set of properties: quicksilver Mercury that tests the definition of a mineral, and double-refracting effervescent Calcite. One is found within thermometers, the other can be used to track the temperatures of ancient seas. Which will rise to the occasio
I love both topaz and corundum, but today I’m rooting for corundum because I’ve always loved rubies and sapphires more and my husband has given me two pieces of jewelry with sapphires, including my engagement ring https://www.mineralcup.org/2023/campaigns/campaigns/campaigns/round-2-match-4
Vote in Round 2 Match 4 — Mineral Cup
If you thought last round featured some hard battles, we were just getting started! But being the standard for Mohs Hardness only scratches the surface of the ways these gorgeous gems are valued every day. Who wins in the battle of beauty and brawn between Topaz (Mohs 8) and Corundum (Mohs 9)?
@Anthro I don’t really know where it came from. It’s possible I bought it, lost it in my car, and completely forgot about it, but the specimen info is missing. One of my friends may have dropped it after a gem and mineral show and it got lost. All I know is that I found it cleaning out my old jeep.
Having a difficult time deciding today for #MinCup23. It’s my favorite teal copper mineral vs my favorite goth girly, Vivian. I’ll probably go with dioptase because of my attachment to my little dioptase friend I found in my car, but I won’t be mad no matter which wins. https://www.mineralcup.org/2023/campaigns/campaigns/round-2-match-3
@tsherrygeo that is simultaneously awesome and mean 😆
Everyone likes showing photos of clear quartz, but I love #quartz because it can be purple (and other colors)! Just look at this amethyst! Stibnite is cool looking, but it isn’t this lovely color. #MinCup23 https://www.mineralcup.org/2023/campaigns/campaigns/round-2-match-2
