I was lucky enough to come across a collection of an old timer that did his collecting in the 50’s and 60’s. I’ve been there a couple times sifting through the collection for a few hours. Tons of stuff there and still more I haven’t gone through. I’ve pulled out almost 2 gallon buckets full of Lake Superior agates. Some of them phenomenal and a bunch of great smaller ones too. They had a garage sale where most of the big samples were taken by the lapidary club and their friends. Someone did tell them not to sell the football sized Lake Superior agate at the sale and it was worth much more than they were asking. I’m sure I missed some great stuff, but have been completely happy with what I got to pick through. I might go broke if the collection was intact anyway. Enough babbling and on to the pictures and questions. The first chunk I’m curious about. ROCK #1 A zoomed in look at ROCK #1.

stewdogg I believe that is or orbicular jasper or possibly poppy jasper. Not 100 percent though.

It almost looks like it has agate in it as well.

That sounds and looks possible to me for sure, perkins17. Here’s another one I need help with. ROCK #2 I can try to get better pics, if needed.

Jesse, that first orbicular piece is SO amazing! I really hope someone recognizes that one!
That second piece has the looks of Picasso Marble. I can't imagine it is...but it has the same type of patterns like Picasso Marble.

stewdogg possibly petrified wood? I don't know. Very unique piece. Bet you could make some excellent cabs

I have a piece of dino bone that has similar orbs inside some of the cells, but tiny, tiny, tiny. So, something with voids that filled. I’d buy the pet wood theory
Probably not PJ. Those orbs tend to be more ragged at the edges — not so perfectly circular
The second one, maybe something like a less colorful Indian Paint Stone, maybe? Both that and Jason’s suggestion would be soft, but PM would fizz with acid and have a white, almost soapy swarf, while IPS would yield dirty swarf — “paint.”

As jasoninsd said the #2 is Picasso Marble. Is Burnies Rock Shop Still around in Madison? Burnie could help ID the rocks if he is around.

jasoninsd, I looked up the Picasso Marble and it does look a lot like the chunk I have. I will do a little hardness test as well. Why do you say you couldn't imagine it is Picasso Marble? I wish I had a bigger chunk of that red one for sure. perkins17 myself or someone else will indeed be making cabs out of that one. Hmm, Petrified wood sounds interesting. stephan Now I want to see a pic of that dino bone. I see what you're saying about the Poppy Jasper, doesn't quite have the same patterns. I will do a hardness test on the second one to get more clues. What type of acid do you use for the acid test? rmf, I'm starting to agree with you guys and lean towards Picasso Marble on the second one. Burnie's rock shop is still around and doing well. They even opened up a second location in town. I think Bernie stopped running the shop in 1999 and his son took it over. I do suppose I could go down there and ask, if the knowledgeable people around here can't lead me towards an answer.

You might have to start taking more credit than that. I think your numbers are better with just my dumb questions.

I do suppose I could go down there and ask, if the knowledgeable people around here can't lead me towards an answer. Anything acid that is sufficiently strong* would do the trick, like muriatic (hydrochloric) for pools or rust removal, or oxalic acid for bleaching/tarnish removal. * I'm using strong to indicate concentration, not strong/weak in the chemistry/dissociation sense. While acetic acid is a "weak" acid in the chemistry sense, the problem with vinegar is that it is too dilute. a 10-20% solution of acetic acid would work just fine (vinegar is about 3%) Making a short story long....

I'm the epitome of the phrase "Even a blind squirrel can find a nut every once in awhile" when it comes to rock identification! LOL In fact I've ALMOST begun to recognize Leaverites when I'm out hounding...sometimes I don't recognize that's what they were until I get home with them though! LOL (Not self-deprecation...just realistic! LOL)

jasoninsd If it is any consolation a friend of mine and I were out fossil hunting and he found an odd pipe like thing. He showed me and I said not interested and we kept on hunting. Just before we left I asked him if he was going to take it and he said no and I said do you mind if I do. So I brought it back home and it sat for about 2yr and then I discovered it was a 70 million year old shrimp borrow. Glad I decided to rethink that leverite.

As far as guessing Indian Paint Stone vs Picasso Marble, from what I've seen of PM, the slashes tend to be clean lines. I associate the "feathery" appearance more with IPS. Not feeling it a 100%, but that's just my gut....

It seems like the colors are more similar to the Picasso Marble and the pattern is more like the IPS…

stewdogg here's the dino bone with orbs: DSC_1429_Dino bone cabochon by Stephan T., on Flickr Look at the cells with white in them. If you click through to Flickr, you can see better on the larger version. Some are even brecciated.

Wow stephan. That's a really nice cab. I bet you could get a pretty good price for it if you decided to sell it. It's very unique.
