was studying origins of life, that got too narrow, now studying #Geology. ... maybe this time i'll regularly post original content, what should i write?

Prepping a little for my astrophysics class that starts on Monday and runs for 10 weeks. Note: I’m 23 weeks pregnant w identical twins, and will be 32 weeks when we’re done.
Can I make it to the end?! Pretty sure my friends have started a betting pool 🙃

It's a bit of a self-limiting process as the serpentine minerals will end up clogging the fluid flow along the fault within something like a few months/years of fluid circulation. Earthquakes along these faults will periodically break through this and allow renewed fluid circulation.

When an oceanic plate bends to subduct at a subduction zone, a kind of "counter bending" happens about 100 km ocean-ward of the trench. This causes lots of normal faults in the plate, which sea water can enter and begin causing serpentinization of the mantle.

the transformations that go back and forth to make plate tectonics gyrate round and round at the mineralogical level.... makes my head swim. threads.
Let's talk about earthquakes in the mantle--a place where earthquakes should not be.

They're all pretty ductile, but most importantly don't sustain unstable slip--they allow slow sliding instead. They're usually invoked to explain slow-slip earthquakes that go on for hours/days, which don't produce seismic waves like those that occur in "normal" earthquakes.

Serpentinization results in a volume change that could induce fracturing at up to ~12 km depth, but not deeper (too much overburden pressure past that depth to overcome).
Deserpentinization results in a small net volume decrease when the volume of rock and fluid is accounted for.

There are a number of variants of this idea. Main point is "earthquakes happen in places where hydrated materials are actively breaking down and releasing water."

The September issue of Highlights magazine is out, so I can finally talk about my article about Sea Angels. They're sweet and pretty, quietly flapping through the sea... until they detect prey, their head splits open, and the tentacles come out.

planets. 10,000 miles wide objects, 100,000,000 miles apart. yet our puny 1" wide eyes can see them. weird and beautiful universe. and of course the stars... 10,000 x 100,000,000 miles from us... still can see them. very communicative universe.
Open up this picture fully.
Then look at the surface of Mars.
Then look up to the top right.
Spot Mars' moon Phobos high in the sky.
Then notice the bright spot beside Phobos.
That's Earth.
