Idk, I'm just a person who keeps doing stuff and ending up in situations.

Funky textures.

Getting my needed dose of 234-year-old drama.

I have received interesting mail.

If you find yourself intrigued by calcite crystallography, I strongly recommend browsing Goldschmidt’s Atlas Der Krystallformen, which has 150 pages of this. Available to view here (log-in is required to view the PDF - but an account is free and easy!): www.mindat.org/reference.ph...

My vote is for #adamite because of the adamite bat. The bat is largely mummified but adamite has started to replace around its face - fluorescent light highlights the adamite. Found by John Seibel, late 1980s at the Gold Hill Mine, Utah, collection of Mark Mitterman.

A dark colored bar is perched on a dark colored rock crag - fluorescing neon green adamite balls decorate the rock and adamite has started to replace the bat particularly around the face.

This is what happens when stibnite “rusts.” I had to unpack a backpack full of rocks for the TSA over this specimen once, and the man was so, so very disappointed when we opened the box and I’m still laughing about it.

‘Stibiconite’ ps. Stibnite • Wadley, Catorce Municipality, San Luis Potosí, Mexico • 13.8cm x 5.5cm x 2.3cm.

Two long intergrown blade-shaped crystals of stibnite (a silver-colored metallic mineral) have been replaced by a crusty yellowish - eh, something, this one is a little complicated. It's probably a mixture of minerals, really, but it’s been called 'stibiconite’ historically. The IMA was arguing about it, I did not hear if they reached a conclusion. For our purposes: it's basically just antimony rust.

One of my favorite things, for being so plain but so incredibly cool: the oldest mineral yet found. Jack Hills zircons have been dated to ~4.4 billion years ago. They were formed during the Hadean (all of earth was more-or-less molten), then cycled into sedimentary grains. #MinCup #TeamZircon

Zircon (medisediments) • Jack Hills, Nookawarra Station, Murchison Shire, Western Australia, Australia • 3.5cm x 3.4cm x 2.1cm.
A sample of metasediments containing zircon grains from Jack Hills - it's a pretty average looking rock, grainy and sort of reddish-pinkish colored. Some quartz grains are visible, the largest ~6mm across. The zircons have been dated to ~4.4 billion years ago (Hadean). There is some shimmery bronzy material sprinkled throughout the mass, and my understanding is that material is the zircons (but I could be wrong).

Behold, a kitten.

A cream-colored kitten with faint reddish/grey stripes on his extremities is asleep on a towel - there are many toe beans and a little curly tail, and he is just obscenely cute.
