Today I found out that was first found down the road from me in Cornwall, so it was a quick and easy vote! Vivianite is a secondary mineral so it appears in a range of geological settings and an even replace organic material~

Well I have a bias for cinnabar. From volcanoes to sediments to volcanoes again and finally lacquerware. Random videos when we were isolated during covid. Mineral Cup #MinCup

According to folklore, seeing the columns was a bad omen. These were ghosts of Vikings who drowned as they were chased to the ice during a battle. Took this pic in the Ikka fjord, Greenland, on a windless day in 2018. Still trembling. 2022

Quartz makes great sand. This thin-section view (cross polarized) from a Cambrian beach of NY State. Well-rounded quartz with quartz overgrowths.

gotta be for me. Not only its kind accomodation of U-Pb dating, but also its often brilliant internal zoning as shown by cathodoluminescence.

Usually I would vote for time-keeper zircon. But I've had some fun playing with fluorite recently. Just look at how pretty it is...

Very sad 😞 for timelord defeat in Mineral Cup #MinCup however one must endure even the greatest pressures as this folded migmatitic gneiss form northern Norway, and go for new challenges (we will have some Zr from this beauty, stay tuned!)
