you need more than only 3, right? i dont know but will send some. Exam in which field? [I am a petrologist, we are a rare breed, so i am certain thats not the field you are going for :)]

One of the things I always loved about Europe is the casual carbonate petrology just laying around being architectural and shit. You don't see so much of that stateside, but sometimes you get lucky. These pillars in Colony Square Mall are clad in a lovely brecciated bioclastic limestone. ⚒️🦪

Aside from bad history takes breaking my immersion, being a petrologist means that every time a movie has fake rocks for plot maguffin, or fake cliff/tunnel/mine/cave scenery, it ejects my suspension of disbelief with Jato rocket assistance.

Any petrologist or mineralogists out there have a ballpark answer to “how long does it take an exposed Granodiorite surface to create a weathering rind that turns to grus?” Assume snowy winters and warm summers.
How long would it take to develop such a surface?

For many, Venus is nothing more than a bright dot in the sky. But not for geochemist and experimental petrologist Edgar Steenstra. He wants to understand how the channels on Venus that are thousands of kilometers long were formed. Since this month, TU Delft has the equipment to investigate this.

OH WOW NOT TO BE CONFUSED WITH PETROLOGIST/GEOLOGIST OTTO HAHN
like I get that Otto's common and rooster last names are common but this one woulda thrrown me for a loop if it weren't for the co-authors

I’m very excited to announce that the always fantastic field geologist Dr. John Wakabayashi is invited as Wichita State Geology’s Watkins Lecturer next Wed & Thurs, 12-13 Nov.
If you’re around south-central KS/northern OK & interested in Earth Science, this is a multi-day event not to be missed!!

October 29, 1882, birthday of Scottish mineralogist and petrologist Samuel James Shand.
At college his first interest was chemistry, to this he soon added an avid curiosity about geology, combing both in his study of igneous rocks and mineral assemblages

I’ve not been much of a talc user but defo never used it since I became a petrologist. Not all actinolite-tremolite is asbestiform but there’s potential for it & other ‘asbestos’ minerals to be present. Talc itself is a silicate so risky as a powder. I’d give it a miss www.bbc.co.uk/news/article...

The claim involves 3,000 people and focuses on internal memos and scientific reports, seen by the BBC.

What exactly do you expect a petrologist to do here? There’s no hidden phase transition in the olivine or pyroxene systems that we are magically going to discover. If there’s a transition at that depth, it must be a compositional change, which is to me a free parameter that I have no data on.

September 29, 1998, died on this day Swiss petrologist and mineralogy teacher Albert Streckeisen.
The Quartz - Alkali feldspar - Plagioclase - Feldspathoids diagram (short QAPF - diagram) for the classification of igneous rocks is also known as "Streckeisen diagram" in his honor.

Also, YES, I met both Nick Zentner and Hannah Shamloo - a petrologist focused on magma, and part of the 1% of BIPOC women with geology PhDs - this weekend, and they were freaking FABULOUS. (I think poor Nick was a bit celeb’d out by yesterday, though, lol.)

^ this is an excellent marine science perspective.
As a petrologist, I see two major issues:
1) they don’t say what reaction mechanism they imagine which will be rapidly sped up by nuking the sea floor. Is it CO2 reacting with mafic glass? Because that’s most of what the seafloor is.
