TheRocksWillShoutHisGlory Posted January 12, 2020 Share Posted January 12, 2020 I found this rock in Lake Michigan near traverse city. It looked curious, is it a fossil? Glacial scarring? What made the bands? Link to comment Share on other sites More sharing options...
MrR Posted January 12, 2020 Share Posted January 12, 2020 Possibly something called: Chlorastrolite (greenstone)? Scroll down the page a bit. Have the stones Link to comment Share on other sites More sharing options...

TheRocksWillShoutHisGlory Posted January 15, 2020 Author Share Posted January 15, 2020 If this was chlorastrolite i'd be quite happy with it, however it doesn't have any green pigment and the pattern isn't as "boxy" Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted January 15, 2020 Share Posted January 15, 2020 I've been looking at it since you posted it and have done a bit of searching but came up with nothing so far. I do get an organic vibe from it, but we all know how quickly that can change with good supporting evidence. I'm thinking it's a bryozoan, but am not finding a good match. I'd like to see photos of the edges and the other side if possible. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

Shamalama Posted January 16, 2020 Share Posted January 16, 2020 Looks like a partially dolomitized limestone, or maybe limestone with chert bands? 1 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted January 17, 2020 Share Posted January 17, 2020 Definitely not glacial scarring. Glacial scarring would disappear when a surface is polished, which this has been by sand and water. Still haven't found anything similar. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
