flic.kr/s/aHsksXBW1rSorry I can only give a link. I haven't figured out how to directly load the pictures to this board yet. I keep finding a lot of these things in my yard, mostly around the trunk of my oak tree. It almost looks like paint poured on top of rocks, but the texture/consistency doesn't fit that scenario. Also, most of them look like coal under the weird outer purplish stuff. It might help eliminate possibilities, if y'all have a bit of history on my lot. It was abandoned and left blighted for a couple of decades. Because of that, it was used as an intercity dumping ground. There is a lot of coal leftover from some of the original structures on the lot. The yard has a ridiculously high lead level concentration, and plenty of old bricks and foundations under the first 6 inches.

flic.kr/s/aHsks4cZkCHere are some more of my back yard findings. I think I can actually identify the coral, but that's about it. I know I can't tumble any of this, or maybe only 1, but I thought a lot of it was interesting, especially in a historical "what the heck was going on in this lot" kind of way. One of my favorites is the rock I linked last night. I'd love to know how the whole bore through the middle in a length wise fashion and if it was done naturally or not.

Hi Alysia. I could be way off since I can't see them in person, but I'd say the first batch are remnants of a fire. Given the history there's no telling if it actually burned there or was debris from somewhere else that was just dumped there. Maybe the house, maybe trash. I'm not a rock guy, but I've been a firefighter for 35 years. That would be my guess; the rock folks may have other ideas.
Please be careful around the lead contamination. Once it gets in your body it's difficult to get out. Children are especially susceptible. Good luck!

The rock that has the fortification looks like some of the material I found in Picayune. About the right size, the material i found was silified and hard enough to tumble well. The corals and the rock with the hole in it also looks like it could have come from that location.

Might also be from volcanic area,crushed up...As said,burned up remnants..I see glass or quartz in a few of them(can't really tell from the photos)..Caution would be advised... Liking the second set of photos,but haven't a clue or guess what or where they came from...

I tried googling partially burned coal, but couldn't find anything. The lead definitely scares me, but there doesn't seem to be much I can do. My youngest had elevated blood lead levels which led me to sampling the yard for testing. The results were astonishingly above normal/acceptable levels. I've tried getting some help from the city and other lead prevention agencies, but I guess 1 back yard affecting 1 family isn't worth the effort. (I was told that her blood lead results were 1 point away from the level that would call for action.) I've tried changing their diets to include more foods that help the body get rid of lead.

The specimens remind me of fulgurites.

Doo, doo, doo, lookin' out my back door.
Your backyard stuff (second post) looks interesting. Here's some guesses.
Top photos - Possibly a natural limestone concretion. Next photos - Coral showing "honey comb" surface Next photos - river worn, or beach worn puddingstone Next photos - banded or fortification agate Next photos - lava used in gas BBQ's Next photos - crumbly mica schist, do the flakes sparkle?
Given that you have high lead, is the "burned material" actually leftover slag from an old metal refining operation? When you tested for lead, did you test the soil but did not ID the source? It may be worth investigating the alleged "slag".
Be careful. Don't play or dig in the yard and don't garden. Dust is a concern, if you are in a dry/dusty environment. If you are on a well, have your water tested for lead. You may be drinking lead and not realizing it.
Darryl.

I found a picture of the rock pile in picayune. My notes are as follows. 10 percent quartz not all white, lots of limestone, limestone fossils and shells. 20 percent black and brown cherty looking. sized 1/4 inch to 1 3/4. We were looking for white quartz for a project. The sand was white silica and the #10 to 1/4 inch had up to 40 percent white quartz rounded pebbles. The operator of the dredge said he could tell when the agatized fossils and agates would pump as he could hear them in the pipes.

flic.kr/s/aHsksXBW1rSorry I can only give a link. I haven't figured out how to directly load the pictures to this board yet. <snip> You're getting good input from folks that know what they're talking about. I would comment on the rocks, but, er...I wouldn't have a clue what I was talking about. It looks like you're getting *very* close to being able to post images here. When you hit the curved arrow icon on flickr it brings up a "share" window. It looks like you are selecting the default selection and copying it. Instead of doing that, click on where it says BBCode. A menu will come up where you can select at what resolution the image will show online. Select a resolution that includes 1024 in either the vertical or horizontal direction. Once you've got the resolution selected then copy the link and paste it in the forum. At least I *think* that's how it's done... Untitled by Alysia Chapoy, on Flickr

The first flickr set and most of the 2nd is cinder from a coal plant/burner, 100%. Same thing they put on an 400 meter cinder track for runners. Used commonly as road gravel. Must have a coal burning generator near by. Or old homesite that had a coal burner, are you up north ? Got over 100 tons on my farm service roads. Sorry, nothing at all illustrious Alysia, a mere man made waste product. coal slag, uncrushed :

y'all are awesome! Thank you for all of the great info, and I admittedly will have to google many of the terms y'all gave me. I swear, it seems like the more I try to learn about rocks, the more confused I get. Does it get easier and start making sense after a while?
James, there's nothing more illustrious than knowledge, except maybe my curiosity being satisfied. I'm so glad you were able to confirm what this stuff was, because it was driving me crazy. And, I was starting to get paranoid and think it was a bunch of petrified animal feces or something that I kept picking up. I'm much happier that it is coal. I'm pretty opposite of up north, I'm down south. (New Orleans)

Cheap and lightweight, stays in place and darn sure gives good traction. Yours is probably from a stove. Especially if you find bits of coal laying around. good to have a mystery solved.
