Helen’s rocks Posted November 26, 2018 Share Posted November 26, 2018 Hello everyone, Please help me identify if this is a possible plant or mineral. First time posting, thank you for your help. Link to comment Share on other sites More sharing options...
daves64 Posted November 26, 2018 Share Posted November 26, 2018 UUmmm.. not to be picky or anything, but we sort of need to see a picture of the item in question.. Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...

Innocentx Posted November 26, 2018 Share Posted November 26, 2018 Nice photos, @Helen’s rocks. If you could post one photo of side one with size around 3mb so we can zoom in, it would really help. So far these look like possible trace fossils. Welcome to the forum from Kansas!

caldigger Posted November 26, 2018 Share Posted November 26, 2018 Looks Dendritic to me. Link to comment Share on other sites More sharing options...
ynot Posted November 26, 2018 Share Posted November 26, 2018 Agree with Caldigger, looks mineral. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Innocentx Posted November 28, 2018 Share Posted November 28, 2018 @Helen’s rocks. Unfortunately I was unable to view your last photo and saw this instead: Were others able to view it? I did notice some circular patterns in your first photo. @caldigger I'm curious, is that normal for dendritic growth?

FranzBernhard Posted November 28, 2018 Share Posted November 28, 2018 To me, it looks like that it has some relief. My gut feeling is, that this is a fracture surface with a thin, partial mineral coating. I think, there is a special name for such features on a fracture surface. Plume structure?? Hackle surface?? But I can be totaly wrong, of course... Franz Bernhard Link to comment Share on other sites More sharing options...
caldigger Posted November 28, 2018 Share Posted November 28, 2018 That's how Dendrites form. Manganese will seep into minute fissures in the rock and spread in fracture directions. Link to comment Share on other sites More sharing options...
abyssunder Posted November 28, 2018 Share Posted November 28, 2018 A lateral view of the specimen is needed. I see voids in the exposed lateral view, but the picture is too blurry to make a more precise idea.
