82. Sunburst

🧠 Glasgow Uni looked great in the setting sun. I really wanted to try some 'breaking the rules' effects by taking shots facing the sun (mirrorless cameras have electronic viewfinders so I wasn't risking eye damage!)

⭐I love the rays coming from the sunlight disappearing behind the buildings. I also like the purple and green streaks to the left (I'm sure they've a technical name I don't know).

➡️ I took this quickly and had to rotate it so the lamppost was straight but that cut off more of the building at the left than I wanted.

#ThinSectionThursday In Archaean times, ultra-hot komatiite lavas were often erupted at Earth's surface. The hottest ones were much hotter than anything erupted today (maybe up to 1600oC). They often show fabulous "spinifex" textures with skeletal/dendritic crystals typical of very rapid growth, like this 2.7 billion year old one from Munro Township, Ontario. Field of view about 2mm wide. Specimen in the #Hunterian museum, University of Glasgow. See Alt-txt for more. 🤩 #Geology #Microscopy

Calcite and perovskite may be battling it out in #minCup25 today, but they can be friends too. Here's an image of a layered rock with perovskite (dark brown) and clear blebs of calcitic carbonatite melt, and spiky crescumulate calcite crystals. This strange rock is from one of the Benfontein kimberlite sills in South Africa. Image is about 15mm wide. Sample is in the #Hunterian museum collections in Glasgow. #ThinSectionThursday #Geology #perovskite #Calcite #mineralogy

#MinCup24 Copper vs Perovskite - hard to choose a favourite today!🤔 Meanwhile, here's a very nice native copper specimen from the Carboniferous basalts of Boyleston Quarry, Barrhead. 🤩 This locality has produced t he finest Scottish copper specimens. This one is about 10 cm long, and in the #Hunterian collections at University of Glasgow... #Geology #Mineralogy

#ThinSectionThursday A beautifully zoned epidote crystal with an older brown allanite core in Lewisian gneiss from the summit of Dun I, the highest point on Iona. From the #Hunterian collections in Glasgow. Field of view about 0.5mm across. See Alt text for more... #Geology #Iona #Mull #Lewisian #Microscopy #Mineralogy

#MinCup23 #Arsenuranospathite vs #neptunite. Arsenuranospathite has a splendidly bonkers name, but I'm going for neptunite. The neptunite in this specimen in the #Hunterian museum collections, from San Benito, California, has a δ41K potassium isotope ratio of 0.21‰± 0.06. It's probably the only specimen of neptunite on Earth for which the potassium isotope ratio is known 😊 🤓 See https://pubs.rsc.org/en/content/articlelanding/2018/ja/c7ja00257b #Geology #Mineral #Isotopes
