One more resource before #MinCup23 voting starts: during the pandemic we discovered the http://www.alexstrekeisen.it/ site run by Alessandro Da Mommio (in Italian and English). It's chock-full of sample and thin section photos, well organized.

Blue #sapphirine is well represented: here a reaction texture between sillimanite and cordierite, in thin section.

#mineralogy #thinSection #photography

#Sapphirine has a complicated structure, with Mg in two sites and Al both four-fold and six-fold coordinated. It has only about 15 wt% SiO2.

It has monoclinic symmetry, but still can form attractive crystal faces when it can grow unimpeded. A good example is on the cover of Dexter Perkin’s on-line mineralogy text, found at:
https://opengeology.org/Mineralogy/

In polarized light, sapphirine changes color with orientation (called pleochroism).

Fully aware it's way more common/popular to cite early/mid 20th century artists/designers/movements as inspiration/reference in contemporary #GenerativeArt, but I've always had _zero_ interest in those (as reference) and to this day been finding my main inspirations in science and natural phenomena/processes...

Ps. Also loving their process overview video and some of the ingenious methods (like using quartz crystals to estimate remaining sample thickness) used to prepare the samples:

For #ThinSectionThursday, I present the NWA 4723 meteorite.

NWA 4723 is the official Meteoritical Bulletin catalog name for a single large L3 chondrite stone recovered from the Saharan Desert in Morocco prior to 2006.

Photo shows a close-up of a single chondrule-like structure. It's unusual appearance resembles a face of some kind. What do you see?

For #ThinSectionThursday, I present the NWA 4910 #meteorite, also known as the "Begaa" meteorite.

This meteorite was recovered from the Sahara near Begaa Morocco in 1999. It was analyzed and officially classified as a LL3.1 chondrite. It is rich in chondrules of all types.

#thinsectionthursday Yey - managed to log in and get my favorite flexible sandstone #thinsection image up.

The thin section scan looks wild enough already

Santa this year brought me a new batch of #Elba #thinsection (s) which included my first 5 thinnies of the #sanbagawa rocks! I am so happy 😍 😍 😍 🎄 🎆 🎇 Happy 2023 everybody! #geology #academia #happynewyear

For #ThinSectionThursday I present the Kapoeta #meteorite.

On April 22, 1942, a single large meteorite fell on a road in a remote area of the Sudanese desert. Analysis shows it is a #howardite type that originates from the asteroid 4 Vesta. Howardites represent the upper-most "top soil" layer of the asteroid - regolith and xenolithic clasts that are remnants of foreign impactors.

For #ThinSectionThursday I present the SAU 008 Martian #meteorite.

SAU 008 was recovered from the Sayh al Uhaymir area of the Al Wusta desert in Oman. It is a basaltic shergottite that originates from the planet #Mars.

Shergottites are an igneous rock composed mostly of olivine, plagioclase, and maskelynite.

For #ThinSectionThursday, this is the Faith #meteorite. Faith is a H5 chondrite that was recovered from a Perkins County South Dakota farm in 1952.

The photo (first image) shows a textbook barred olivine #chondrule. I was so enthralled with this perfect chondrule that I decided to paint it (second image).
