This stuff is much prettier and shinier in real life. It's pretty amazing stuff. We call it brain rock because it looks like a brain when you find it, they are round and crinkly on the surface with lots of cracks and holes. I busted one up because it had a bunch of interesting color. You really never can get rid of the holes, but once they are shaped and smoothed out I really think they are pretty.  pup is yappy today. |

That reminds me of some of the bits and pieces of Mex Crazy Lace I got from Kingsley North.

We have a lot of local stuff that looks like crazy lace -- I guess maybe this is MO lace agate, with more than the usual number of holes?

Hi Puppie I was wondering if you have identified what you're "brain rocks" actually are. I have a bunch of rocks, that I also call "brain rocks" that I found here in Michigan that I am trying to identify. pg.photos.yahoo.com/ph/jlc0321/album?.dir=6726&.src=phAbout the first 20-30 pics look similar to what you have pic's posted of. Thanks for your time. Jeff |

Looks like either Missouri Lace Agate from the lead mining area of SE Missouri or Crowley Ridge Agate from southern Missouri.

Hey Jeff!
Got to ask, where in Michigan did you find those "brain rocks"? I'm guessing that they were found in the UP on the "Big" water! Man, I would love to let my slab saw spend some time with them!!!
Both puppie and Jeff have brains that I like!!!

Hi Jeff,
Yeah, yours look a lot like the ones we pick up, except that yours are really much smoother than a classic brain rock, which is really swiss cheesy. The ones in the photo had been tumbled a lot to get as smooth as that. These are that quartzy rock family that includes chert/flint/jasper/agate. The brain rocks that I pick up would qualify as agate, probably, because of the banding. There's often crystalline quartz in there. The colored/opaque red/gold ones are jaspers.
Sabre, I'm really impressed that you know Crowley's Ridge agate. I would never have heard of it except that Shawn made the same comment and I looked it up. You are right, it looks very similar to my stuff.

Yeah, Jeff - Where did you find those rocks? I live in Mich., too, but never have come across ones quite like that. I'm prolly not lookin' in all the right places (a lot of concrete here where I live).
And, Puppie - Does the grit get stuck in the rock holes when yer tumbling 'em? How do you manage to get it all out? They are really cool rocks & I'm assuming that you find them right where you live. Lucky you!

Hi Pebbles,
The majority of them came from a job I was doing in Oxford, Michigan. The site could have been used for a gravel pit. Some of them came from a job at 11 mile and Milford road in Lyon Township.
I work in underground construction(storm sewers, water
mains, etc...) so I am constantly coming across rocks/fossils that we dig up.

Hi Bill,
No I only have one rock that came from Whitefish Point, and I think it is a laker. The rest of the rocks pictured came from either Oxford, MI. or South Lyon, MI.
I've been told "lakers" can't be found that far south. I've also been told that they can, so I don't know. I'll probably get a saw next summer and start cutting some.
I've broke a few of the smaller ones open, some were banded, some had a drusy lining to them.
I plan on hitting the U.P. next summer if I'm not to busy with work.
Thanks for looking.
Jeff

It's interesting looking rock, to be sure. And it does kind of remind me of (I now have the willies) chunks of brain.

Yeah, pebbles, the grit and mud will get inside the cavities. Except for times of the year like now, when the hose would freeze, I rinse mine outside in a colander over a bucket and squirt them well, which gets most of the stuff washed out. I'm using a vibe with a separate polish barrel, so when I get to the polish stage, I wash it under the hose and then put it back in the barrel with a few drops of dish soap, some borax, some water, and about a quarter teaspoon of an aluminum oxide polish. I let it run for a while and wash them again and put them in the polish barrel with the final polish.
