Thin Section Thursday! contributed by Reagan Elizabeth Davis, UG student at James Madison University. The rock pictured is a Kyanite Quartzite gathered near Ogilby California. (XPL) Kyanite shows low to moderate interference colors, and bladed form. #ThinSectionThursday #kyanite

Rare blue yoderite replacing kyanite (-talc + quartz). Only found in two places on Earth (Tanzania and Zimbabwe), yoderite forms at high pressure in hot subduction zones from rocks rich in in Mg and Al, poor in alkalis and Ca, in the presence of water and oxidized ferric iron (±Mn).
Named after Hat Yoder of the Geophysical Lab, CIW.

With #Kyanite in the final, better purchase your samples today (from your favourite retailer) before the prices go up!
Own the winner for a reasonable cost!

The Montreal Gem and Mineral Show is happening at the end of the month in the main convention center (Le Palais des Congrès).
No guarantee of fantastic #Tugtupite or #Kyanite samples, but many others for sure. There's always a good representation of Canadian and Quebec localities.

Wouldn't it be amazing to have a kitchen counter top made from kyanite?!

Repost: Kyanite isn't just a fetching blue mineral that documents the experience of sediments under extreme duress.
It's an ore: Virginia alone mined 83,000 tonnes in 2023. Kyanite in furnace insulation transforms to mullite when heated, expanding to reduce porosity and shrinkage.Virginia Kyanite (photo: J. Wyman) from:

This is one of the dykes found near Ayer's Cliff, just SE of Magog, Quebec. It's a set of three dykes, one of which has the deep-derived xenoliths. That one dyke (not photogenic) has weathered much faster, perhaps due to a higher carbonate content.

A photo of a Cretaceous dyke intruding into Appalachian-deformed sedimentary rocks deposited in the lower Paleozoic: Earth history from 110 to almost 500 million years ago.
But #kyanite records more of the story: it's part of xenoliths brought to the surface by these dykes that document Grenville crust (1.1 billion years old) at depth.

Look “space green” kosmochlor may be of meteorite origin and occasionally carved as it’s associated with jadeite, but blue kyanite definitely gets the arts vote for jewelry and use in porcelain and pottery glazes. Plus is gets physics points as an index mineral. #MinCup25

With #kyanite I always remember this video created by Stacey Phillips via the Mineralogical Society (the LEGO stop motion science videos) -

Alright fine. I guess we're doing red vs blue (someone who paid more attention to RvB than me should haul out the quotes.) (... well okay it's more that I've never seen the first like. Idk 5 seasons? With captions so I genuinely dgaf. I have an autograph from... someone roosterteeth circa 2010 tho), so ANYWAY tangent aside, while the meat rock looks tasty, you can't eat it. So one must go with #kyanite!! #MinCup24

Okay I know it's early hours yet but how is #kyanite beating out #dioptase?? Come on. I love the practical geological indicator it is too (and also it polishes up super pretty as well!), but like... Dioptase tho. Let it have its year in the spotlight! 😆
