Cyberpunk is the idea that technology will condemn us to a future of totalitarian nightmares here you can discuss recent events and how technology has been used to facilitate greater control by the elites, or works of fiction

Post geological formations, rocks, and anything geology or geoengineering related here.


Sorry if this doesn't belong here but this is the closest thing to a /sci/ board we have.

This is the Palo Duro canyon. 2nd largest canyon in the U.S. and the largest canyon in Texas located near Amarillo. 190 miles long, on average 6 miles wide, and about 860 feet deep.

Do people want the /cyb/ board renamed to "/scig/ - Science and Technology, and their effects upon society and the human imagination"?

So I'm contributing to the thread, check out the Crystal Cave in Naica, Mexico
>Nothing compares with the giants found in Cueva de los Cristales, or Cave of Crystals. The limestone cavern and its glittering beams were discovered in 2000 by a pair of brothers drilling nearly a thousand feet below ground in the Naica mine, one of Mexico's most productive, yielding tons of lead and silver each year. The brothers were astonished by their find, but it was not without precedent. The geologic processes that create lead and silver also provide raw materials for crystals, and at Naica, miners had hammered into chambers of impressive, though much smaller, crystals before

Nah. It's not like it's taking up any space.
Just keep dumping. Feel free to give us something to read too.

God damn I wanted to post about that one just now

/cyb/ is fine

I would like the name to be changed because I think it would encourage more discussions. We should put it to a vote.
Pic is Alexandrite
The alexandrite variety displays a color change (alexandrite effect) dependent upon the nature of ambient lighting. Alexandrite effect is the phenomenon of an observed color change from greenish to reddish with a change in source illumination.[8] Alexandrite results from small scale replacement of aluminium by chromium ions in the crystal structure, which causes intense absorption of light over a narrow range of wavelengths in the yellow region (580 nm) of the visible light spectrum.[8] Because human vision is most sensitive to green light and least sensitive to red light, alexandrite appears greenish in daylight where the full spectrum of visible light is present, and reddish in incandescent light which emits less green and blue spectrum.[8] This color change is independent of any change of hue with viewing direction through the crystal that would arise from pleochroism.[8]

These are from Carlsbad Caverns. If any of you ever get the chance to go you really should check it out.


I have a magnetite, an osbydian, an amethyst covered by volcanic rock and some tiny rocks like quartz and interesting ones, but my collection is really small compared to my mother's, she has a lot of rocks, one day I will have a collection as big as hers.
Do you also like rocks anon?

Postojna cave, Slovenia

I have some, but rather than specific materials, I search for weird shapes.

I remember touching an Iron meteorite while visiting a travelling space expo, though.
Just thinking "this thing comes from outside" sent chills down my spine.


I have a pretty large rock collection. I used to go fossil hunting when I was younger. I recently got a facetting machine so I can teach myself how to cut some of my stones.

These are ammonites. A species of molluscs closely related to the nautilus that went extinct about 65 million years ago.


It's so cool how crystals form in the shell cavities of invertebrates.


Golly, what caused the crystals to form in there?


When you say it like that, that sounds horrifying


Well some of those seem to have tiny edges, I wonder if this creature got it's organs hurt by them.


They were deaf long before the crystals started forming
Minerals were slowly deposited in the cavities over time and they slowly crystallized over a very long time.


Probably the fact that the shell is hollow and filled with a different material. I actually have a couple clams filled with them that I picked up in Peru.
The thing was long dead, flesh long gone, by the time those crystals started to form.


This thread is making me want to go look for fossils again.

This is calcite and its crystal structure.



>The tsunami bomb was an attempt during World War II to develop a tectonic weapon that could create destructive tsunamis. The project commenced after US Navy officer E.A. Gibson noticed small waves generated by explosions used to clear coral reefs. The idea was developed by the United States and New Zealand military in a programme code named Project Seal.[1] The weapons concept was deemed feasible, but the weapons themselves were never fully developed or used. A related concept, the bouncing bomb was developed and used in World War II, to be dropped into water as a means to destroy German dams and cause loss of industrial capacity and widespread flooding.

That was attempted during WW2. I wonder what could be done with modern technology.

>tfw moved to Florida 5 years ago
>no rocks
>moved fom Connecticut (glacial state)
>Still miss the rocks


Move to Texas. We have all kinds of fossils here from marine life, to petrified wood, to wooly mammoths, to dinosaurs. Also lots of opportunities for geologists.


does fracking get maud aroused?


Plausibly… or the opposite.
Would you be able to tell, if she did?

>The Yellowstone Fumaroles in Wyoming are an incredible display of color and geochemistry. A fumarole releases gases such as carbon dioxide, sulfur dioxide, and hydrogen sulfide, among others. Fumaroles deposit an array of minerals with the combination of acidic gases and high temperatures.

Small amounts of a material called "Louisiana Opal" or "Louisiana Sand Opal" have been mined from the Catahoula Formation near Leesville, Vernon Parish, Louisiana. If you examine this material closely, you will find that it is a sandstone in which the sand grains are bound together by a cement of clear precious opal.
