Answered my own question:
Aplite dikes are fine grained or sugary textured intrusives of granitic composition.

"aplite" dikes, such as found on Eichorn Pinnacle often have smokey quartz and feldspar crystals, along with muscovite.

I was going to say... I'm a climber and a Geologist, and I don't have a rock collection...

Then I realized... I have rocks from Fontainebleau, Monsant, Stanage, Hueco, and other areas that I have been lugging around for 15 years.

But Locker it is good schist!

Seriously our last few outings have been really good. We have to get-em polished up. When we do there should be some real gems in there.

We are on track to find some green agates in a new area we are going to get to as soon as there is a low enough low tide.

Oldest Rock on Earth



"It's a zircon, from the Persian word "zargun" meaning "golden colored," an extremely durable mineral found all over the world. This one turned up in a dry, hilly region of Western Australia. It was sitting inside a larger rock, and when scientists checked, it turns out this little grain formed around 4.4 billion years ago. That would make it the oldest rock we've ever seen on this planet, old enough to know secrets about early Earth, old enough to tell us a little something about how life started here."

Here's a cool banded iron formation:

Here is my new passion. Take the rocks I have polished and do something with em. I am really liking doing the wire wrap on the rocks. It is meditative and I seem to have the knack for it.

Here's my little collection. Mostly samples of Sierra granite and volcanic rock (obsidian) collected from road cuts and stream beds. One hunk of West Virginia coal. And the shale samples are from the Wadi Rum in Jordan.

I have always had a love for the Earth Sciences and elements, minerals, rocks, and now even meteorites.


G-d as described in his Good Book, well he's way into them also ...


Makes sense I would like them too.

The coolest rocks aren't the pretty crystals, which are only one mineral.

Take some granite. Go to a lot of trouble to extract the zircons. Do some more washing with harsh acids.

Then you can date a rock several billion years old with amazing precision.

Every rock tells a story, which is why I love geology. When you put them all into the proper relationship with each other, you can see the history of the planet.

I don't think that there was a single gemstone class offered when I was in school, and there still isn't. The cool rocks may be as simple as the Wingate at Indian Creek.

Crystals have fluid inclusions, and you can hit them with the electron microprobe and tell the chemistry of the parent melt.

Hell, ice is a mineral, and obsidian, strangely, doesn't fit the definition. We don't really care, because obsidian implys super fast cooling of a basaltic magma.

Hopefully I didn't get any of the igneous rock stuff wrong. I work entirely with sedimentary rocks, and I think that they are far more fascinating.

I turned down a choice job offer at graduation with the USGS because it was mapping volcanics in Nevada. Boring.

I would just like to say that it's very hard to identify a meteorite from a picture. Scientifically it's impossible, since it has to be validated geochemically, etc. etc. etc.

Having said that, I zoomed in on the image and its pretty grainy. Unless you give me a clear image of each specimen up close, I don't have a chance.


A stony-Iron is like a Pallisite:

Mostly metal with some minerals.




Marvin Killgore holding up a massive slice of his famous Chinese Pallisite meteorite that he purchased from a Chinese nomad for very little. Not good karma.
