Man made waste of some sort, a glassy slag if I had to guess. Been learning a TON this last week on naturally occurring rocks, meteorites and manmade slag byproducts from dfferent eras and different materials

I actually found some opalized slag at an old foundry site a while back.

Here's one: It's dense, from a quartzite matrix,and I know it's a hematite, but what variety?

I found this on a hike, I believe it to be corundum not sure, its rough as can be, it has a reddish brownish color to it its 5/6 sided, terminated top and bottom, ill appreciate your time an thoughts, sweet on the thread I have more sweet specimens, I'm new to the site thanks, here are pics, I have a video to get a better look at it.

top one is Jasperiod, commonly has large loads of fine gold in it,, yours may have been reheated (IE sub crust and forced back up),, should also possibly have Calaverite View attachment 778969, i have seen this formation alot ,, its AuTe2 and a bugger to seperate ..lol

the bottom one is a mixture of Chrysocolla, and lapped quartz with mineralization.. i would say that its really heavy due to the copper, magnesium, iron, silver, and titamium within the quartz.. in a scholars terms Copper Manto development immediately beneath the andradite garnet – epidote – carbonate – hematite skarn with green (chrysocolla) – cuprite – chalcocite (grey) and ochreous hematite – limonite developed in the oxide zone after copper sulfides.. lol but a good spot to look!

that picture is pretty spectacular.

Here are some rocks I am wondering about. The first two I found in Holy Jim Canyon. The other two I found out in East Fork San Gabriel River. The big rock is magnetic where it is grey.

 

[hbprospector]

Chuck, holy Jim is an active claim,

 

[chuckufarley]

I wasn't out there mining... just picked up some rocks.....There are claims, its true. hbprospector... thanks for the heads up... I like your videos very cool stuff. It's not all claimed up there there are some areas that are open....I checked.

Looks like molybdenite.

Can you help me with these rocks

the two little gold-colored ones were found in the Cold River Vermont... I am very curious about these...
The green ones...I believe is Slag glass found in Irondequoit Creek in New York
The Brown one was found on Newcomb Beach in the Adirondacks.
The Blue/brown one was found in Schroon Lake, which I also believe is slag

Thanks so much!

 

[wilfndgold]

Quartz, Mica.

Found some more giant quartz bolders also found a tun of mica this stuff looks metalic shinny almost chrome but when you look at it its actualy a bunch of thin layers and its clear like glass kind of heavy to neat lookin. check it:

Why has this thread been moved to the Hard Rock Mining section from the Rock/Gem section??

Shar,

That piece with the penny is interesting. If it was slag I wouldn't expect to see the creamy material with it. Have a closer look at that. Also, look here for answers:

Looks like you found yourself a pegmatite vein. The last pics you show are probably Muscovite, a mica. Keep an eye out, there can be quite neat stuff in pegmatites.

 

[Hillbilly Joe]

Found this in the Montana countryside, any thoughts or ideas?

 

[MrLee]

Lots of Black Tourmaline out there as well as garnets, rose quartz & beryl. It's a mountain loaded with goodies. I've recently got some black tourmaline with garnets attached from there. Some of the tourmaline is bigger than your arm, but it's in solid rock. The mica is thick everywhere.

 

[Hillbilly Joe]

Thanks!

[h=2]Heavy Hunk of Rock[/h]

A friend asked me to find out what I could about this specimen.
It weighs 21 pounds.
It displaces 6 cups of water in a bucket.
Dimensions are roughly 7" x 6' x 4 1/2".
It is magnetic but more so on the end that looks volcanic.
It came in a load of rock from the California Sierras.







Any ideas?
thanks-​

 

[chuck_turner]

Okay, Mr Lee and I have discussed these two specimens. Let's see what you guys think. The first 5 pictures are crystalized quartz, mostly. What else is in there? The next 7 are of a rock found really close to the first. It wasn't pretty, the material looked comparable so I broke it up. What do you guys see? The specimens were found in Hart County, GA, on my property.

Meteorite fragment? You may wish to have it sectioned and acid washed...
