Quartz cluster w/ 3 different habits. Mayflower Mine, Colorado.

Do want. I'll give you $20 if you sneak that out of the collection for me.
I think I'm going to take up chain smoking so that I'll have some cool tins for my own specimens.

Good to know that all this opal won't affect my throat.

He has thousands of things. The minerals are gangster.
Maybe the old thread got archived.
Azurite w/ some malachite, Bisbee Arizona.

Get a load of the back here
>>2150621
looks almost organic.
"Eisenkiesel", what I think is referred to today as ferruginous quartz. Ellenville NY.
A few vials of herkimer diamond, some with fluid inclusions, others with hematite or cavities. These were apparently found by the collector's wife, not the collector himself, as its her name written on the labels.
I'd like to emphasize right now that these things are in no way an effective filtration mechanism for anything, and you should most definitely not pay 50 bones a bottle for any vodka that claims to have been "filtered" with herkimer diamonds.
Quartz cluster. Unknown locality.
Milky Quartz. Camp Bird Mine.
>>2150660
pretty
Herkimers in matrix. Per the collector's notes, the highest clarity Herkimer diamonds are associated with the carbon-calcite matrix in the forground.
Quartz with hematite, rutile, and actinolite. Gothard Switzerland.

The newspaper it was wrapped in is kind of interesting too.
Santa Barbara, California, News-Press. Thursday, December 11, 1980.
Rainbow-iridescent obsidian, Stauffer Oregon, 1935.

Loved the other thread you made not to long ago OP show me more bone stuff fossils.
>>2151469
Oreodon Jaw, Tertiary-Eocene, South Dakota
>>2151489
I guess this is where the canines were attached.
Cross-sectional slices of coral from the Capitol Reef, Utah. I guess he managed to get to it before it was declared a national park.
>>2151469
Cross-section through a piece of dinosaur bone. I'm not a paleontologist, so I don't know, but my friend is and he says that the abundance of red pockets in the marrow there indicates that whatever creature this came from was relatively active. I guess more iron=higher metabolism?
>>2151509
Fuck that's really neato
>>2151469
This isn't quite a fossil but uh....
Whalebone notebook.
>>2151520
From Catalina I guess?
>>2151521
It's full of pressed flowers.
>>2151524
No wait, the bone is from Monterey. I suppose the flowers are from Catalina.
Also, come on, bone sidewalks? That sounds like some kind of Tim Burton-y Halloweentown gimmick. Is this real life or a Warcraft lorebook?
This is by far the coolest thread(s) on 4chan right now.
Please keep posting regular updates as you photograph this stuff.
>>2151557
I'll try to keep a steady flow of pictures. Was surprised there isn't some "Rockhound General" or something here.
Finishing for the day with another piece of "Blue Vitriol". Not as pretty as the first, but this time with a locality: Butte Montana. I guess this stuff might have something to do with how toxic the water in that hole is.
>>2151574
how did you acquire this collection?
>>2151574
yeah, it's produced by leaching of copper oxides into sulfuric acid which was known as "oil of vitriol."
presumably dissolving your specimen there in water would likewise produce blue vitriol, sulfuric acid plus copper.
>>2151499
>I guess he managed to get to it before it was declared a national park.
yeah, though collecting fossils in Ntl Parks wasn't always a problem. The fossils belong to the people, back before about 1975 this was interpreted as whatever people happened to find them. Similar situation with cultural artifacts & etc. Used to be you could collect arrowheads and Anasazi pottery and dinosaur bones on public land without a permit.
not so much anymore.
>>2151509
Kinda depends. The large cells are cancellous bone, aka trabecular bone.
this is from the inside of a very large dinosaur bone, likely a sauropod limb bone.
the colors of the minerals filling the pockets are probably not representative of the actual tissues present. The red, e.g., is probably not iron from dinosaur heme. Red cells in dino bone are just common where red inclusions and fossils are found in general. The coloring isn't associated with any particular biology, particularly in agatized bones. It's worth noting that the cell walls fossilize before the interiors do, so whatever is inside the cell has washed out probably millions of years before the interior minerals were deposited. Unfossilized dino bone does show up on occasion, but it's almost always white with black and brown stains. Usually pretty crumbly too.

Schorl in mica schist. Danbury Connecticut. 1934
Calcite scalenohedron w/ light coating of secondary growth crystals and galena. Locality unknown.
Calcite scalenohedron w/ much heavier layer of 2ndry XLS. Cherokee Mine, Treece, Kansas.
>>2152215
Can see the host crystal here on the bottom.
Apparently Treece is a ghost town now, so if anyone lives nearby, go sneak into the mine and get some more of these.
>>2151456
More obsidian from same locale. This one is labelled as silver iridescent, but I'm not really seeing silver here...

Amethyst. Siberia. 1931.
Pyrite, sphalerite, and dolomite on galena. Leadville Colorado.
Pyrolusite. There's a note with it, but it seems to have been written by dipping a caterpillar in ink and letting it run around on the page, so I'm not sure of where it came from or when.
Smelted copper.
Ruby Jack/Zincblende, what is referred to now as sphalerite, with saddleform dolomite crystals on dolomite matrix. Scott Mine, 240.5 deep, Hockerville, Ottawa co. Oklahoma.

Keep your eyes peeled next time you're up there.

I take my kids up there to hunt pyrite, we find some decent cubes.
It's famous for its gold, here's a piece a guy with a metal detector found a few years back in the road. Currently listed for $2500 on ebay.
I mostly hunt saloon tokens and copper minerals up there. People have dug up tons of gold from the property in the last few years, much to the irritation of the mine owners.
I make more money working for the owners than stealing from them though.
>>2153206
Here's some of the junk we find up on the mine dumps there. It's a particularly good spot for acicular malachite, azurite and jackstraw cerussite.
>>2153243
Pretty sweet.
>>2152424
Neat, I live on the Des Moines River near Madrid.
>>2153267
thanks.
This is one of my favorite Leadville ores I've found- sphalerite with triangular chalcopyrite and galena.
Jenny June Mine, Leadville District.
this particular specimen was in the remains of the mine super's cabin. Those Victorian miners loved to collect some rocks.
