GeneralLimonite Concretion!

6th Oct 2019 17:44 UTCWayde Harville

So neat I think

First photo, strictly speaking is not a geode; looks more like a chert nodule with a hollow center. Whether it is petrified wood (if yes, it would also not be a geode), I cannot tell from the photo. 

Second photo... a nodule... probably from a sedimentary environment.  Also not a geode.

Third photo, a sedimentary chert/chalcedony nodule with a hollow area. Also not a true geode.

Hi Wayde,

This is not petrified wood but rather a goethite/limonite concretion. Such things, though not exactly like yours, were sometimes called Indian Paint Pots because the center was oftentimes filled with that earthy tan limonitic material that could serve as a paint when mixed with water. I used to find these quite commonly in the glacial till at a gravel pit near my childhood home in Wyoming, MI. Sometimes I would break them open and they would be hollow like your first photo and other times there was a loose earthy tan nodule inside that could be removed leaving the harder shell and a botyroidal interior of the piece. Oftentimes, these would be loose and one could hear them rattle inside when the piece was shaken. Rarely, I would find fossil invertebrates like crinoids or bryozoans attached inside---these were quite rare and I think that I only found two in the thousands of hours that I spent at the gravel pit when I was a kid! It is basically an ironstone formation and not petrified wood. Still, very cool things. A couple of years ago I visited a gravel pit on a vacation back home in MI and looked for these but found not a single one. They were almost always found in the unconsolidated till with much sand, etc. and we used to dig for them in the side of the large hill that was the edge of the pit. Thanks for sharing!

Hey Dana I'm sorry for that reply. My account has been messed up and it wouldn't let me. But thanks for the help i appreciate you all correcting me because i new but very eager to learn because I'm so interested by

25th Oct 2019 07:50 UTCWayde Harville

It only puts part of my replies idk what's wrong but I just typed out a long reply. But to shorten it up I wanted to add better photos to see if you could help me identify if this is a Indian artifact!

25th Oct 2019 07:51 UTCWayde Harville

If so I would love to add my first artifact to my new lil collection! I'd be proud! Thanks for your help and I hope you the best hunt on your next gravel pit adventure! It sounds so fun! Thank you

This is why I thought of Petrified Wood! What do you think?

25th Oct 2019 07:56 UTCWayde Harville

I sprayed it with some clear coat. I really love how it turned out it's the perfect lil cabinet piece. My nephew loves it and keeps his fav pen in it

25th Oct 2019 08:01 UTCWayde Harville

I like this photo

No petrified wood, but a limonite concretion (we have things like that here in het Hageland, Belgium). But I understand why the more or les concentric/layered structure reminds of wood.

25th Oct 2019 09:44 UTCWayde Harville

Thanks for the expertise Erik!  So you don't think this could have been a Indian Paint Pot? Either way is okay with me I think they are so cool! Appreciate the reply!

Wayde, now that you are starting to notice these things and getting into it, try going to a library like I did and pick out some picture books of rocks and minerals especially if there is a book on rocks in your area, usually your state.  Even the elementary school kids rock books are great to point out what the differences are in the common rocks and how they are classified.

I have seen tubular limonite/siderite concretions forming around fossil wood, but see no evidence of it here.

26th Oct 2019 09:43 UTCKeith Compton Manager

No one was suggesting that this could have been actually used as a paint pot by Native Americans, only that such concretions are sometimes described as Indian Paint pots. So, no it is not an artifact of any kind whatsoever.

Hi Wayde,

Keith is exactly right. Perhaps I should have used "Indian Paint Pot" to describe the specimen. The ocher interior, when water is added, creates a paint that was very likely used by cultures all over the world in times past. Perhaps even today.

Collecting artifacts is an interesting adjunct to mineral and fossil collecting. In all my years of looking at the ground I've found only one arrowhead...and a poor one at that! And some shards of pottery (one inch or so pieces) that I left at the site.

I doubt whether any of the objects WAYDE has shown us are Indian artifacts. HOWEVER, 
I JUST REVIEWED KENTUCKY'S LAWS ON THIS SUBJECT:    "excavating, digging, and EXPLORING FOR INDIAN ARTIFACTS ANY PLACES WHERE THEY MIGHT BE FOUND IS A FELONY".         The pertinent websites are easily found on the internet.

Simply put, Wayde probably needs a artifact collecting permit in his area of London, KY (especially if he wants to use photos to show off his finds for identification).

Anyway, most of what he has found are ironstone or limonite concretions from a sedimentary origin. Relatively resistant after the surrounding limestone has long ago been weathered away. These nodules and concretions are common in Kentucky/Indiana creek beds and woods etc.   

As to petrified wood in Kentucky, Wayde's examples are not. There probably is some, associated with very common fern fossils; some online examples are misidentified also being limonite and ironstone nodules and not petrified wood.   The fern fossils and wood are in geologically much younger rock associated with Kentucky's coal beds in the western  and southeastern parts of the state. Not near London.          CHEERS.....BOB
