PostPosted: Jul 13, 2018 19:50    Post subject: Green slime  

Hello everyone and thanks for all your help and advice in advance. I look forward to getting your opinions on this. And Ive learned a great deal just reading through every new thread that pops up in my email.
This is my first post.

A little about myself. I farm and ranch east of Denver as well as back in Kansas where I grew up. Ive always been interested in Native American artifacts, minerals, gems and everything else nature blessed us with.
If you wanna know anything more about me just ask.

I'll try to describe everything about this find. Last week we were visiting family outside Salida Colorado and we took some time to rockhound and pan.
I was panning on the Arkansas river and decided to move downstream to another bend and had to take the railroad tracks to get there due to a cliff and stumbled on to these rocks. They were evenly spread throughout the ballast rock on the tracks so who know where they originated.
Ive studied everything from serpentine, to onyx, omphacite, nephrite, tourmaline, malachite, and it even kinda looks like maw sit sit.

These samples are roughly the size of a baseball. I forgot to add a quarter to the images.
What you see in the pics are completely dry with absolutely no oil or anything else on them.
I say that obviously because they look so wet, waxy, greasy, etc.
The greens are vibrant and I believe the black is actually extremely dark green.
Some of the bases appear volcanic in origin but some appear bonelike.
There are small megnetic inclusions in some. One is exposed and has a hex shape (on the top edge of the slim, pie like sample).
It looks porcelain and waxy but extremely hard. Somewhere in the neighborhood of 7.
They are not fluorescent under UV black light.
And some of them have a blue hue instead of green.

Very odd stuff. I'll try to upload around 8 images.

Based on their appearance, if they're not slag (which is likely), they're probably a mix of chrysocolla and malachite mixed with silica or tourquoise. If not either of those, something else very similar I'd say. It looks like they'd make good lapidary material for making cabachons and whatnot, so if if it's not slag, then I'd say you have a great find there!

Thank you. You're right it would make great cabachons.
As far as slag, I'm not familiar with it. Slag from a smelting process?
Could be but the back sides look very volcanic but like I say, I'm not exactly sure what slag is. I'll have to study up.
For some reason I keep thinking wind river jade. Or like you mentioned, a greenish turquoise.
I asked cousin who works for that railroad and he seems to think it may have come from either Vaugh New Mexico or Granite Wyoming (areas / quarries).

I'm with Matt, they appear to be some form of slag. Your railroad story fits, as here in Canada, slag from the nickel-copper smelters were commonly used on the rail beds.

I think you guys are right on. I just did a search for 'green slag images' and pulled up very similar specimens. I will post one.
Thanks so much for the, what looks to be identification.

I forgot to mention, when I place the Geiger counter on the areas of magnetism it shoots way up on the usv/h.
And those little magnetic pieces are he size of a wooden matchhead and octagonal.
Im not sure if I wanna keep it in the house.

Looks like slag. "Shoots way up." Is that a scientific term? Just kidding.
