Banded Iron Formation

Here's a photo of a beautiful 3.4 Ga banded iron formation from the Barberton Geo Trail, South Africa. It's heavily weathered, but there was still some green underneath the oxides. Exposure is ~3m high. #Geology

While both metamorphic and sedimentary rocks undergo processes that transform them from their original state, they have distinct differences in their formation, characteristics, and properties. Here are the key differences between metamorphic and sedimentary rocks: Read more here:

Trivia Tuesday!

Do you know what metamorphosed quartz is called?

Micaceous Marble? Calcareous Schist? Sometimes metamorphic rocks aren't so cut-and-dry.

#but for realsies #if anyone knows a consistent way to class metamorphic rocks with mixed lithologies pls point me to a source #im dying out here #in which cube is a geologist #metamorphic #geology

in order: two different species of ammonite, three trilobites of two different species (one of which is still in the matrix)

#FOSSILS BABEY!! #rambles #geology #not *as* into paleontology as i am geology as a whole #esp igneous and metamorphic rocks #so these are the only kinds of fossils I really have #they are Sick As Hell Though and I’d love to expand my collection… #they’re just expensive lol #anyway!! the smaller ammonite on the top is slightly opalized and exhibits flashes of red/green :] #incredibly cool #OH AND THE SPECIES THING IS AN INCREDIBLY ROUGH GUESS

Intruded Pelite

#ThinsectionThursday A carbonate vein intruding a 3.2 billion year old pelite. Greenish mineral is chlorite, dirty grey brown material is carbonate, pale grey white material is quartz, opaque material is pyrite. 4x Magnification #Geology #Metamorphic

Conchoidal Fracture and Burial Metamorphism wld both be pretty solid band names I think

#ok burial metamorphism is a bit clunky but conchoidal fracture has good fricatives #i think a lot of geology terms wld make good band names

Hello ! Has someone already asked you about your most hated rock ? The rock that annoys you the most ? The harder rock(s) to study ? Have a great day !

Hi! Actually, not until now. I do not have a ‘hated rock’, as in every rock an interesting story can be found. But if I had to pick one, I think it would be a marble.

Marble is a metamorphic rock which originally was a limestone (a sedimentary rock made up of fossils of ancient sea creatures) that was transformed/recrystallised by intense heat and pressure. Because of this metamorphic transformation, fossils in limestone rock are often destroyed and much of the rock’s earlier history is erased. But of course, that’s not to say that there is nothing that can be done with it!

Thanks for your question! Dr Rock.

Sedimentary, metamorphic, and igneous!

hey girl are you a silly man? because you're a high grade metamorphic rock

#studying for my geology exam is melting my brain #this phrase just came into my head #(the joke is sillimanite is a high-grade metamorphic rock.) #ocean.mp3

We interrupt your irregular schedule of thin sections to introduce hand samples! Any ideas on what the main minerals are? (Hint: they're all metamorphic rocks)
