Something quick for #MineralMonday, a pretty little beryl (aquamarine, I reckon) I broke out as an exemplar cyclosilicate for lab a couple weeks back. ⚒️🧪💎

No #MineralMonday today. Without contributions from people like you, I have nothing to post.

Would you like to feature your research, field photos, a neat mineral, a recent publication? Please send information and up to 4 images to akoziol1 at udayton dot edu.

Quick #MineralMonday from me! Have a few hematite included quartz and smoky crystals! Also congratulations to quartz winning the mineral cup!

A cute little rhomb of rhodochrosite, a shape you see in other minerals with a similar crystal structure. #MineralMonday #GeoscienceBluesky ⚒️🧪

For this #MineralMonday, I’m continuing to celebrate Quartz’s victory at #MinCup26, and to photograph the quartz specimens in the collection.

Here is a prase flower, a leek-green variety of quartz, with its characteristic slender crystals.

Welcome back to another #mineralmonday

Here is a cut and polished slab of Banded Fluorite from China. Fluorite can form in hydrothermal veins that carry large amounts of calcium and fluorine. Those veins find open spaces in rocks and eventually cool and crystallize.

A really cool massive halite crystal with a fluid inclusion!! Halite is a Mineral Cup favourite this year. #MineralMonday #MinCup26 #GeoscienceBluesky ⚒️🧪

Let's not forget that it's Monday, as the final contestants in #MinCup26 face off in nerve-wracking do-or-die showdowns.

For this #MineralMonday, here's a yellow specimen of Uranocircite, a uranium-barium phosphate with a striking yellow color.
