Mr-glomeroporphyritic - Expect Nothing

Trying to reorganize my rock collection on my shelf by how much I want the specific rocks to be displayed. The problem is that I'm a geology major and I love all of them

Happy Ace Week, everyone!! No matter where you are on the ace spectrum, you are celebrated this week! And if you are learning about asexuality, we hope that this week will prove helpful.

[image description: a purple square with the text "Happy Ace Week!! October 22nd-28th, 2023." There are illustrations of a rainbow in the asexuality pride flag colors (black, gray, white, purple) and a purple star character with a smiling face. The AVEN logo is in the lower left corner.]

YOURE WELCOME!! THANKS FOR READING ABOUT THE ROCKS I THINK THEYRE REALLY GREAT

i wish i had a geologist friend who could sit me down and tell me everything about these rocks and what kind of rock it is and how they were formed and everything about them:(

theyre just normal rocks but i want to KNOW about them.

ftr I am forever going to be bitter that the post I wanted to be "let's talk about extinct ecosystems and how cool they are!" got derailed into yet another post just talking about a single taxon like the millions of other posts on palaeoblr

“we only have bones as evidence so every scientist is just guessing stuff, right?” 🤨

wait are chickens actually decended from t-rexes or is it just a comedic pairing

Chickens and T. rex share a recent common ancestor, more recent than T. rex shares with Stegosaurus or Brontosaurus/Apatosaurus

Chickens did not descend from T. rex, because T. rex is a very specialized and derived dinosaur

However, they - and all other birds, because all birds are in a single group - descended from small raptorial dinosaurs like Velociraptor. And, the common ancestor of Velociraptor and all birds (including chickens) could fly

And since birds descend from the same common ancestor as all other dinosaurs, they're dinosaurs.

Hullo-geology student.

These looks like fluvial, or river, cobbles. They get the rounded shape from moving down-stream, the rounder the rock the longer they stayed in the river.

The top one on the right, sort of white-ish, looks like a chert pebble. This is made of the same stuff as quartz, and is super resistant to weathering, so they last a long time, especially in river systems.

Both of the middle ones look sort of like granite or perhaps a breccia. Breccia is a form of sedimentary rocks where smaller rocks get cemented together and make a bigger rock. The angular shapes of the rocks looks like feldspars, indicatinf a granite that got weathered. I think that the bottom left one is also a granite.

The top left one and bottom left one I dont really know. They both kinda look like granites, but it is difficult to tell. The bottom left one looks like it cooled with magma mixing, so there are larger grains with smaller ones, a texture called porphyritic.

I should note, this is based almost entirely on grain size, coloration, and pattern. I am also guessing because I don't know the geologic history of the area. Soooo i might be wrong but this seems like the most likely based on the images.

Thanks for showing me rocks i think theyre really nice

Just because we aren't seeing more posts about Palestine, doesn't mean the genocide has stopped. Let's keep Praying and speaking up for Gaza, Palestine.
