geology memes are the schist. they're so gneiss, you don't even have to mine too deep for them

What's the difference between a tabular body of silica-rich igneous rock and a lesbian who has fallen ill?
One's a felsic dike and one is a dyke who fell sick.
Thank you, the booing makes me more powerful AND less funny actually.

The geologist's joy:
I am wearing my green hiking pants, the ones that zip above the knee -- all the better for packing light, I've learned. I lived out of a carry on last summer, no room for luggage amidst the rock samples and the chatter, the sunburnt skin, sweat and joy.
I am wearing my green hiking pants, this I remember -- their hands brush against them, soft. That's what you learn in the field, how to look for and how to find, amidst the dust, the smallest sparkle. A moment, a little thing -- pick it up, hold it up to the light, grit humming under your nails like a heartbeat.
So much wonder in a pebble, so much story, if only you slow down to look. The dance of tectonic plates, the roar of an ocean long dry -- some long field days, sun-kissed, I want to carry each stone against my skin like a gemstone bead. There's beauty in story distilled.
We bump teeth, laugh, pause -- they ask if they can unzip my pants at the knee. Not the hips, not yet. For now, this is perfect. Little moment, remember -- I in my green hiking pants, they in their jeans, spring thawing outside their window, a hope, but never a promise.
This may be a pebble, nothing more and nothing less, a bead in a chain of stories, neither a promise nor an epic, just a glitter -- but I know how to read pebbles.
I know how to hold a moment in my open hand, brief and sparkling as a gem.

Turn a three mile hike into a five mile hike with this one simple trick: constantly pace back and forth to look at neat rocks.

morally grey/evil scientist characters are always like biochemical engineers or nuclear physicists or whatever but the people want VARIETY give me a story about a fucked up geologist for once

Eternal Flame Falls sounds like the coolest concept for a fantasy book. A path you follow down into a ravine until you find an ever-burning flame inside of a waterfall? That’s fuckin metal! But it’s not in a fantasy book it’s like an hour away from my house I can literally go see it any time! I remember it like once a month and lose my shit over it every time

I got a Geiger counter!
Let’s look through my collection for some Spicy Rocks! I’ve never deliberately collected radioactive specimens, so I have no idea what I’m going to find.
First, though, let’s test the baseline level of radiation in my house.
It’s fun to hear the Geiger counter click as it detects radiation. 20 counts per minute. Nice! You’re unlikely to ever see a count of zero, as pretty much everything in the world, including the human body, gives off a little bit of radiation.
20 is a normal baseline, nothing to be concerned about. Standing in my house, I’m getting a radiation dose of about 0.00013 milliseieverts per hour - or a little over one mSv a year. This is an average yearly dosage of radiation for people in my country, and is something my body can easily process. For context, a dosage of 100 mSv would slightly increase my risk of cancer, and a dosage of 1000 mSv would immediately give me radiation sickness.
But enough about these boring, safe amounts of radiation. I want to see some spice! Let’s check over by the Rock Wall!
Hm, I’d expected the CPM to be noticeably higher around my rock collection, but I’m getting nothing! Even testing each individual rock, nothing’s more than a few ticks above the baseline. So far, my fancy new toy is looking like wasted money. :c
WAIT! THERE!! 62 CPM! That’s three times higher than the base reading in the rest of my house!!! YESSS!! THIS ROCK IS SPICY!!!!
Here’s the rock that’s setting off my Geiger counter. (Yes I’m touching the spicy rock with my bare hands, don’t worry about it.)
This fossil, which is as big as my head, is part of the femur bone of a Megalonyx, a North American giant ground sloth!
These huge animals could grow as big as ten feet tall. They lived alongside humans during the last ice age, and it’s theorized that humans may have hunted them to extinction. This particular fossil was found in a phosphate mine!
Why is it radioactive? Because… sometimes fossils are just radioactive! They spend a lot of time in the ground, which is full of radioactive minerals, and often radiation just gets all up in there. There are some fossils on display in museums which are so radioactive that they have to be coated with lead paint for the safety of curators and museum-goers! Compared to those, this femur bone is barely radioactive at all.
So is it really safe for me to have this in my house, much less handle it with my bare hands? Well, yeah! Remember, despite having this spicy rock in my collection, the radiation baseline in my house is completely normal. Here’s why.
Even just a few centimeters away from this specimen, the Geiger counter’s reading is halved. A few inches away, and it can’t detect any radiation at all. It basically has to be directly touching the rock to get an abnormal reading. Which means I also have to be touching the rock to receive a meaningful amount of radiation exposure.
But even holding this rock in my hands, I’m only getting a dosage of about 0.0004 mSv per hour. If I never let go of this rock for an entire year, I would get a dose of about 3.5 mSv. Which is… still completely within the safe threshold for my body to process. Nothing to worry about!
Man, I gotta start collecting some spicier rocks.

Geological horror. You find a geode and crack it open and the crystal lining its walls is human blood that can't be genetically matched to anyone. You find a human skeleton but every one of the bones is made from rock, a rock that you know can't be whittled into those shapes. You find layers of clay and loam that sport ancient fossils at the top and the still-rotting corpses of modern animals at the bottom.

In 1935, quarry workers in Port Madoc, North Wales used a unique device to ride the rails when returning from work. The device consisted of three wheels and a hand brake.
