I love both minerals! Hematite makes BIFs, one of the best rocks, plus it has so many habits and finishes. Haüyne makes gorgeous blues and it likes to capture bubbles and other minerals as inclusions. It also has some cool patterns on thin section. TS images: www.alexstrekeisen.it/english/vulc...

Sorry to hear about the passing of Danny Thompson. Enjoyed him many a time live as the perfect partner to John Martyn’s mesmerising guitar and vocals. Hope they are playing together again somewhere. youtu.be/UQQYLV9ir5A?...

Found this amusing: "I would like the odometer to register in kilometers instead of miles ... I record my *mileage* and it would be handy to have the odometer display kilometers"

Following last week’s #WaterfallWednesday, Brian’s sent another gem – Hull Pot full to the brim in January 2023! After heavy rain, Hull Pot Beck spills in, creating a spectacular waterfall. Occasionally, it even fills completely! 🌧️ #Ribblesdale #YorkshireDales #StepInToNature

St Mary’s Chapel, Grandtully, a remote Perthshire chapel whose interior comes as a magnificent surprise. The chapel was probably built in about 1533. It was refurbished in 1636, when a painted ceiling was inserted in its eastern half. More pics and info www.undiscoveredscot... #Scotland #Perthshire

#kyanite fields forever, or until the next orogeny #MinCup25

Today I’m voting for the pretty blue mineral with 2 different hardnesses depending on the direction you test it! #kyanite #MinCup25

There's a shady character on Queen Street. Twice in the year, at the vernal and autumnal equinoxes, the dawn light shines right along Ingram Street, turning the Iron Duke, his steed, Copenhagen, and even his traffic cone hat, into a shadowy work of art. Picture: u/Hoyerman68

North Chesthill Estate is trying to stop walkers enjoying 4 Munros in Glen Lyon during all of Sept & Oct. #ScottishOutdoorAccessCode is clear on 🦌 stalking: Landowners can manage routes on specific days, but NOT force unreasonable blanket bans. We hope @perthandkinross.bsky.social can intervene.

My vote today goes to the green mineral first found in a meteorite: #kosmochlor. Why? Well, my bachelor thesis was in weathering of the El Hammami meteorite to determine weathering products a meteorite sample can develop once it has hit Earth. Meteorites are so cool and interesting! #MinCup25

T20. Blimey. Salt peppered the boundary.

It's not a tank unless it's from the Tank region of France - otherwise it's just a sparkling armoured fighting vehicle

Wait just a minute. #Tugtupite is fluorescent, phosphorescent, pleochroic, piezoelectric AND nicknamed “Reindeer blood”? Sorry #Pollucite. I was wondering what the #MinCup25 version of “Meat Rock Mania” would be. I think #Tugtupite might be it. Vote: www.mineralcup.org/2025/vote/r1...

Cs is great but how cool is #Tugtupite? It contains Beryllium, which is also very rare and the red color results from small amounts of sulfur and not some Fe or Mn. When pale tugtupite is exposed to UV light or sunlight, the red color intensifies. #MinCup25

Before… After…

7 Sept 1870 // Experimental turret ironclad HMS Captain sank in heavy seas off Cape Finisterre. Her overweight and overmasted design with high centre of gravity and low freeboard caused her to capsize. About 472 of 490 men and boys on board died.

I choose the feldspathoid #leucite over the hydrocarbon mineral. Won’t catch me voting for a hydrocarbon #MinCup25

Anyway, compare the emulator version (left) and real hardware (right) and you can see that the emulator is optimistic. This may be down to my settings, or it not timing some nuance of the hardware correctly. Regardless, DMA it is for super-fast filled graphics. Moral - test on real hardware kids.
