Looks like some of the stuff I have pulled out of my creek.No tumbler yet so will be watching for yours. I don't care if its not fancy all my stones will be from Missouri and go into jewelry. There are a few geodes to be had North of Stockton if you ever venture thata way. Not very much of interest down here in the Ozarks

I pulled the unknown rocks out of the tumbler today. I'll try to get a picture up of them later on. These rocks came in bag from Home Depot for less than four bucks. They were different from any other rocks I've see in the area stores (I hunt while I'm shopping, too!) so I thought I'd check them out. But, I've decided to take them out and replace them with some quartzite in the Money Pit. I did leave 3-4 pieces in the tumbler just to see what they might do, though I'm not expecting really great things.
I saw what I thought was the edges of seashells in these rocks so I busted one up. Sure enough, little seashells...only a couple in that rock, though. Upon closer inspection there are also small druzy pits/cracks in them...really sparklers...but, those druzy areas are really small as are the crystals, but man they sparkle!
What I am interested in is later, when I get my small saw running, is to cut into some of them. I don't know what it is, but there is creamy white areas in the rocks, clearish areas, and the tan areas. It will be interesting to see what the saw reveals.

Could be some agates and jaspers in there. Looks like agate in the center of picture #3.

I thought I'd got more pictures than these, but these two will give a pretty good idea of how the rocks look. Mostly brown/tan with opaque white, and some clear areas. Some of the rocks appear to be breccia(sic?)...little pieces of the brown/tan stuff in white. Seems there are a lot of healed fractures (glad I learned a little about healed fractures ). Some of the little cracks and crevices have some very tiny sparkly crystals in them. And as I mentioned, some shells in some of them. The last two pictures is of a rock that is a lot different from the other rocks...lots of layers....pet wood?....pet onion?<g> IMG_9773a (Custom) by Intheswamp, on Flickr IMG_9772a (Custom) by Intheswamp, on Flickr IMG_9771a (Custom) by Intheswamp, on Flickr IMG_9770a (Custom) by Intheswamp, on Flickr

This thread has become tangled a bit but here's my input. The original rocks struck me as chert or flint. Finding a shell fossil in one says chert. A silica product laid down in aqueous solution (probably sea floor depoits). Your last photos do not sway me from my bias toward chert. The onion specimen is intriquing in that the layers are not very parallel. If this was something biological growing most of the layers would parallel each other or at least be the same thickness in a standardized way. These lines appear to be more stress fractures that left lines. Its hard to envision how they were produced concentrically, but maybe. I'd slice the onion and see if they appear different in the interior. I'm interested in how you thoughts evolve as you tumble or polish. Tom

Howdy Tom. Thanks for the input. I've got to continue studying rock formation so I can give you a good response to your statements. I learned several things from them, though, thanks for sharing. I like your thoughts on "the onion"...you are correct, the lines are not "rings within rings" as there may be a ring that suddenly starts and another one starts backup 1/8" away...kind of staggered. For now I've set them to the side until I get my saw going...when I get it going I'll cut a few test rocks and then run this one trough to see what it looks like inside of it.
