When your mutuals only ever talk about high grade metamorphism. Call that an eclogite chamber

happy birthday heavensward, metamorphism is my "i love heavensward" fic, i promise

Serpentinite that's becoming peridotite again, thanks to contact metamorphism

Staurolite:
- A silicate mineral
- Forms during regional metamorphism
- Can be used to determine the grade of metamorphism
- The state mineral of Georgia, USA
- Its name comes from the Greek word "stauros" (cross) because it sometimes forms cruciform twins #minerals

For #RockinTuesday I show you this neat #eclogite slab exposed in an open air museum in the Besshi area (Shikoku, Japan). Along the usual red garnet and green omphacite, this rock contains quartz, calcite, rutile, zoisite, kyanite, and phengite.

FOV about 10 cm.

Benitoite on natrolite with neptunite. Benitoite is a barium titanium cyclosilicate. Formed when Ba-bearing hydrothermal fluids pass through Ti-bearing blueschists during retrograde metamorphism associated with serpentinite mélanges.

as a sociological phenomenon, its fascinating to see the jensen huang metamorphism. First from crypto and now this

i figure you get your 20s creativity from jamming your head with shit for 20 years then having it undergo metamorphism; i jammed my head full of normal sci fantasy shit. im now preparing for my creatuve 60s by intentionally jamming my head with a bunch of fucked up shit that isnt sci fantasy

Living under the weather,
Call it an #umbrella term.
Living under pressure,
Call it metamorphism.

Bold of you to assume sedimentation, crystallization, metamorphism, and weathering of minerals aren't “proper character development”

yeah we thot feldspar, but mind you it is from the Franklin Marble, which has crazy minerals. and yes metamorphism. over the hill (less than a mile) was a crumbly schist.

a secret third thing (metamorphism)
#wolqotd / #wolquestion

When faced with a difficult situation does your wol / oc grow stronger or crack under pressure?

Need clever examples of P-T estimates of contact metamorphism around the world. With 'clever' I mean situations in which you find the right assemblage that really narrows it down to a limited pressure and temperature interval :)

You will get cited! ☺️

Titanite forms in high pressure & temperature environments associated with metamorphism, & is an indicator mineral used to infer the geological history of its formation. Its beautiful crystals have a wide range of colors due to the variety of REE it can store in its crystal lattice. More 👇🏼 #MinCup25

Textbook: 'contact metamorphism is static'

The thin section:

In my experience, I have never seen fully static contact metamorphism, but that's maybe because Tuscan plutons aureoles are very deformed. Anyway, I am pretty tired of reading this sentence in textbooks 🙃
