I got a rock for my birthday! I had to use a hammer to open my present. #geode #geology #crystals

thanks to this thread I was able to get Xorg working on my AMD LX TR2350

I first got a black screen when using VESA, but adding "1024x768" to the "Modes" finally got me something usable.

I blame @ltning for making me try this...
I even spent 4EUR for a 512MiB SO-DIMM 🤣

Sometimes eBay still does work!
Needed a PC2700 SO-DIMM >128MiB.
Checked eBay, found a 256MiB and a 512MiB for a very reasonable price and 2d later: here it is.
Working fine in my LX mainboard...

Been examining this rock I got for an incredible £5 today under a 60% microscope and I honestly can’t express how incredible it is. I wish I had a macro cam so I could share it with you guys, but damns. Bands, points, zigzags, eyes, botryoidal forms. I’ve died and gone to heaven #rocks #agate #geode

So I think I should share "Media" right away so folks know it's really moi - how about a rock? This "rock" is one of my more "famous" rock photos. I took it in a glass display case at the Tucson Gem and Mineral Show years ago in 2007 with a point and shoot camera. The "rock" is an amazing geode from the Bisbee mines and owner called it "Velvet Beauty". Back then it was valued at $25,000. I have thousands of photos on my flickr account that is now about 20 years old. Yikes! #Cobalt #Rock #Azurite #Geode

Geode from Bisbee Arizona opened up a little to show off the azurite druzy, fine medium to light blue crystals covering the interior of this large azurite and malachite specimen.  It is mostly cobalt blue with swirls of shite and green bits from the malachite.

I did update my based for the cheap board to 2024.8.1

Purple heart amethyst geode

A quick post about some quirky geology today.

Geodes are crystal-filled masses inside a larger body of rock. They are awesome. Scientists generally know how they form. Voids or bubbles in volcanic or sedimentary rock (particularly basalt/lava) were inundated with hot, mineral rich, fluids circulating in the ground. Crystals grew from the fluids – like rock candy grows on a string in a saturated sugar solution.

Geodes are typically small. Quartz is the most common crystals that grow in geodes. My grandfather brought me a round geode he got in Alaska that he called a thunderstone. I had a geology professor use a rock saw to cut it open to reveal a crystal bridge inside.

But some geodes can be massive. I recall seeing, in person, at a rock shop in Trump Tower in NYC in the 90s, an elongated amethyst geode several feet high. Amethyst is quartz that has atoms of iron substituted in the crystal lattice or has been exposed to radiation. I could not imagine how this massive cluster of crystals could have formed. Its price reflected its rarity. Giant geodes like this are typically from Brazil and Uruguay.

The most interesting amethyst geode I ever heard about was a heart shaped crystal cluster that was found by miners near the border of Uruguay and Brazil, where the geodes began forming over 130 million years ago. The rock was split to reveal two sides of the geode that had a clear quartz edge and a deep purple center.

Come on! That’s pretty cool!

Amethyst is a key economic resource in northern Uruguay where it has been mined for over 150 years. This area is recognized as a geological heritage site because of the amethyst here has such a deep violet color and high quality, as well as the giant size of some geodes that can be several meters in length. Even though scientists know generally how the geodes are formed, a recent study in this area of Uruguay suggests additional details. The scientists studied the fluids in the geodes and in the surrounding rocks and determined that the amethysts crystallized at low temperatures from groundwater-like fluids. This may help discover new areas of exploration.

Geodes are just Blind-Box Toys for Kobls. Think about it - you hand them a rock, and they have no idea what kind of shinier rock is inside it until they crack it open!

In unrelated news, do not take Kobls to museum giftshops. They will bankrupt you.

A pair of kobolds holding geodes. One is nervously lining up the hammer to crack theirs open, the other has already done so and is admiring the shiny rocks inside the big rock.

A quartz-filled geode from Mont Lyall, Gaspe Peninsula, Quebec. These form in Devonian volcanics of the Chic-Choc mountains, when hot water percolates through cavities. The quarry is a pick-your-own-nodules, with a service to saw them open -no guarantees!

A cavity within a pale brown volcanic rock has been filled with the mineral quartz; the center of the cavity is still open, surrounded by faceted quartz crystals.
