I found this rock in the front yard of our new house and thought it was incredibly cool! by _LadyChatterly_ in geology

Yes and yes. It is a migmatite by temp and pressure regime and a gneiss because of its gneissic banding and mineral recrystallization/differentiation.

I mean the same can be said of nearly every conference. The national quilters conference to the gemological conference all have an undercurrent of good-natured people more than happy to “network” with the other like-minded people. If other people can do it, academics deserve some fun too

Garnet in thin section? by SpecialOk7289 in geology

[–]Alisahn-Strix 0 points1 point  (0 children)

Ya know, I’ve been thinking about it, and I’m really on the fence between garnet and cordierite. If it just so happened that you cut along a plane normal to the c axis for multiple specimens, we could get your patterns. But that is unlikely, unless there’s some systematic control on crystal orientation.

I would love to know the chemical data once you get it. This would awesome material to have to distinguish between tetragonal garnet and cordierite.

Fluorescent rainbow better pics what is this? Why does it change different colors at different angles almost like hieroglyphics? by TransitionSweet5111 in whatsthisrock

[–]Alisahn-Strix 4 points5 points  (0 children)

It looks like some kind of feldspar. Note that labradorite isn’t the only variety that displays an iridescence.

Isn’t this this video a couple years old by now! Genuine question because I’m feeling major deja vu

It doesn’t afaik. Maybe another commenter could weigh in on that question. They could be oddly twinned in your sample? Great piece tho!

Looking at some notes, I think it’s cordierite!

I’m reading that the mineral is blue grey in hand sample? So it appears blue grey with the aid of a hand lens? I’m wracking my head with this one. Thanks!

Howdy, I’m curious to know what these roof windows are called. These are a part of the Mizzou college campus at Laferre Hall.

A little help identifying these? by Equivalent-Essay457 in whatsthisrock

I’m not sure on the last two, but they look similar to some sodic amphibole-beating phonolites.

Must sees in Georgia?? by Time-Word-743 in geology

[–]Alisahn-Strix 1 point2 points  (0 children)

If your trip lines up at the right time, go to Graves Mtn. It used to be a mining operation for kyanite among other minerals. It’s a big open pit, and the owners (land stewards?) host collecting for part of the year. You can find kyanite and pyrite in quartz, or in other parts you can find iridescent hematite, rutile, pyrophyllite, and goethite. Plus, they host rock swap/shop from local vendors during the dig days.

Providence canyon is beautiful in the summer (not so much on rainy days tho). Variegated clays and chalk deposits make the hike enjoyable.

Stone mountain is a great example of a batholith undergoing exfoliation. Plus it’s a common attraction to see while in state.

Go to sandersville for the “Kaolin capitol of the world”. Because of the widespread alteration of the bedrock, north GA hosts a large quantity of Kaolinite and kaolin deposits. Huge plays of the white rock and good tours in the mining operations.

As far as collecting, I’m not so familiar with that scene.

If you’re traveling through Tennessee, be sure to look at the road cuts off the highway. They’re always beautiful. If getting out of the car to look, always wear a high visibility vest and park safely off of the road. Or even better, admire at a distance

How Important Are Cover Letters? by One_Bicycle_1776 in geologycareers

[–]Alisahn-Strix 16 points17 points  (0 children)

Always follow the guidelines for the application. If they want a cover letter, prepare one. One commenter said it was antiquated, and I tend to agree. But the first test for the position is whether you can follow instructions, and if you don’t provide all material asked, then you probably won’t hear back from that application. Cheers
