#Durangite is associated with hydrothermal alteration of glassy volcanic deposits. What a striking change in chemistry to replicate the color of hot magma! Image of flame-colored, tabular crystals from mindat.org #MinCup24 🧪⚒️

For today’s #MinCup24, we’re voting for #Durangite, both for its rarity and striking red color.

Durangite gets its name from Durango, Mexico, where it’s found in a tin mine. Learn more about the geology of Mexico (and check out our Spanish translations!): https://t.co/q3EUBWCLQC

Typical #Wavellite spheres from Třenice, Czech Republic. The yellow color on surface is caused by #Cacoxenite.#MinCup24 #MinCup pic.twitter.com/0QBqagipBQ

Both contenders this round are aluminum bearing minerals- one a greenish phosphate and the other a reddish arsenate

But wavellite gets my vote! The morphology of the globular aggregates lend to a beautiful surprise of radial fibrous crystals when cut or fractured#MinCup24 https://t.co/xWXfqV1iAR pic.twitter.com/hHaJVnN5WH

Is it just me that thinks radiating #Wavellite crystals look like slices of kiwi fruit? #MinCup24 Image sources: commons.m.wikimedia.org/wiki/File:Wave… commons.m.wikimedia.org/wiki/File:Kiwi  en.m.wikipedia.org/wiki/File:Wave

2 rare minerals collected for their looks Durangite is found in veins in ryolite & in pegmatite dikes through granite Wavellite forms in fractures in aluminous metamorphic rock, in hydrothermal regions & in phosphate rock deposits. It gets the art vote for its use in cabochons & jewelry #MinCup24

Wavellite just looks neat 🤷‍♀️ What is everyone’s favorite flavor of this mineral? Broccoli, lime, beans or moldy meat? #MinCup24

Now it’s time to recruit more players! Chat in the comments or on the social media platform of your choice (tag us and use #MinCup24 when you can). Everyone deserves to learn more about minerals, choose favourites, and enjoy.
