They had form even before that. Verses and instrumental (except one bar) of Curfew also in 7/8.

Have had a quick look and could not see any with ocelli but a marvellous variety of relationships between olivine, plagioclase, and clinopyroxene. Might have to post the "pegmatite" one for next week's #ThinSectionThursday!

😍 I have not seen this. I am about to return the one I shot to the department collection and will look for others like yours. The one I shared was collected by (Ulsterman) Henry Emeleus and we have so many more from NI.

Photomicrograph of olivine dolerite. Isolated, euhedral to subhedral olivine phenocrysts (showing second and third order interference colours) are surrounded by a groundmass made up of opaque iron oxides and an ophitic intergrowth of small, euhedral plagioclase laths surrounded by large clinopyroxene crystals.

Spectacular olivine dolerite from Fair Head, County Antrim in XPL for #ThinSectionThursday. Olivine shows particularly vibrant interference colours while the ophitic intergrowth of twinned plagioclase and clinopyroxene is a textbook quality example. 🧪⚒️🌋

Michael Ort was a marvellous guide when we took a party of @durhamearthsci.bsky.social undergrads there in 2007.

I know your pain. My lad’s first two years in a football team involved an all maroon strip. Two years I had to cheer that 😐😂🇳🇬

Indeed. Although the last general election suggested the is a fairly reliable sense of the need amongst electorates in many, especially marginal, constituencies.

True. But @jamesrball.com’s original point was that Reform pronouncements are also in hindsight but without attempting to look at the actual distribution of votes.

There’s a few of us on here. Lots of artistic landscape and rock stuff appears on my feed. Don’t comment on all but lovely to see. Cannae beat a good rock!

Almost certainly - hence its overall very rounded shape and fairly smooth surfaces. But that is a long, long time after the formation processes I described.

That is a migmatite. The dark bands recrystallised while being heated and compressed to produce their layering. The pale bands were melt (either sweated out the dark or intruded later) and crystallised. The whole thing was squished while hot giving the wavy appearance. ⚒️🧪
