The Silicate Garden

"A chemical reaction creates colorful growths with a remarkably organic appearance (hence the "garden" name). The process is similar to crystallization, but in contrast to ultra-orderly crystals, this is a self-organizing non-equilibrium process that creates complex structures."

Yellowstone National Park, WY (No. 23)

Yellowstone is at the northeastern end of the Snake River Plain, a great bow-shaped arc through the mountains that extends roughly 400 miles (640 km) from the park to the Idaho-Oregon border.

The volcanism of Yellowstone is believed to be linked to the somewhat older volcanism of the Snake River Plain. Yellowstone is thus the active part of a hotspot that has moved northeast over time. The origin of this hotspot volcanism is disputed. One theory holds that a mantle plume has caused the Yellowstone hotspot to migrate northeast, while another theory explains migrating hotspot volcanism as the result of the fragmentation and dynamics of the subducted Farallon Plate in Earth's interior.

The Yellowstone Caldera is the largest volcanic system in North America, and worldwide it is only rivaled by the Lake Toba Caldera on Sumatra. It has been termed a "supervolcano" because the caldera was formed by exceptionally large explosive eruptions. The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 37 miles (60 km) long, 18 miles (29 km) wide, and 3 to 7 miles (4.8 to 11.3 km) deep. The current caldera was created by a cataclysmic eruption that occurred 640,000 years ago, which released more than 240 cu mi (1,000 km3) of ash, rock and pyroclastic materials.This eruption was more than 1,000 times larger than the 1980 eruption of Mount St. Helens. It produced a caldera nearly 5⁄8 mi (1.0 km) deep and 45 by 28 miles (72 by 45 km) in area and deposited the Lava Creek Tuff, a welded tuff geologic formation. The most violent known eruption, which occurred 2.1 million years ago, ejected 588 cu mi (2,450 km3) of volcanic material and created the rock formation known as the Huckleberry Ridge Tuff and the Island Park Caldera. A smaller eruption ejected 67 cu mi (280 km3) of material 1.3 million years ago, forming the Henry's Fork Caldera and depositing the Mesa Falls Tuff.

Why choose between who to ship who with when you can just make them all a polycule

Felt like giving her something casual

[felikatze]

trouble differentiating sulfite and sulfate? got a problem with halogenides? just rely on your DEAR OLD FRIEND KALIUMPERMANGANAT, THE ONE WHO DOES IT ALL!!!

No reducing substances in my sauce no sir no sir we got sulfate in this house 🫡

Happy new year India! :D

May this year bring you more silly and cake

Cursed DametaGala interaction that just popped into my head.

Galacta Knight: Hast thou been scratching again?

Dark Meta Knight: ...Maybe. Why?

Galacta Knight: There's glitter everywhere.

We need a new longest word. I like pneumonoultramicroscopicsilicovolcanoconiosis as much as the next guy, but it's less fun when you learn it describes a painful disease

50 Million Years of Climate Change with Christina!

Have you ever thought about how dinosaurs lived on a warm, swampy Earth and how we live on one that’s cold enough to keep pretty much the entirety of Greenland and Antarctica buried under kilometers-thick sheets of solid ice and wondered, hmm, how did we get from there to here? The short answer is that it took 50 million years of declining atmospheric carbon dioxide concentrations and dropping temperatures, not to mention building an ice sheet or two. For the longer story of the last 50 million years of climate change, including some of the reasons why, catch this episode of our podcast with Dr De La Rocha! You’ll hear about plate tectonics and continental drift, silicate weathering, carbonate sedimentation, and the spectacular effects the growth of Earth’s ice sheets have had on Earth’s climate. There are also lessons here for where anthropogenic global warming is going and whether or not its effects have permanently disrupted the climate system. Fun fact: the total amount of climate change between 50 million years ago and now dwarfs what we’re driving by burning fossil fuels, and yet, what we’re doing is more terrifying, in that it’s unfolding millions of times faster.

Bonus content: If you want to see sketches and plots of the data discussed in this episode, you can do so here!
