Lone Hunter Posted February 26 Share Posted February 26 Going through my bucket of unknowns and no better way to describe this. Found in creek with mix of Cretateous and alluvial deposits. Originally thought it was wood, not so sure now, I've never seen these spots before that look like they're floating. So tiny hard to get clear pics of the white spots that look like a flower opening and some of the spots appear to be holes at the surface. Must be biological in nature I'm thinking but what? It's pretty whatever it is. 2 Link to comment Share on other sites More sharing options...

Brandy Cole Posted February 28 Share Posted February 28 This most resembles a piece of banded chert to me with really interesting mineral inclusions. At least that's what I would think if I found it. 1 Link to comment Share on other sites More sharing options...
Lone Hunter Posted February 28 Author Share Posted February 28 More like spotted chert I haven't seen chert with these colors which is why I mentioned jasper, but haven't seen anything like this. Would love to know what the minerals are and why only the white spots rise above the surface. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted February 28 Share Posted February 28 (edited) If it is hard and does not scratch with a metal knife then it might be orbicular or poppy jasper. The orbs which sometimes have a radial pattern may be harder than the surrounding rock and thus stick up. See picture of Kinradite with protruding orbs from near San Francisco, California. https://www.flickr.com/photos/36618387@N06/4284363384 Edited February 28 by DPS Ammonite 1 1 My goal is to leave no stone or fossil unturned.

Lone Hunter Posted February 28 Author Share Posted February 28 Indeed it is poppy jasper thank you! Found an image that shows exactly what I couldn't quite get with my camera. 1 Link to comment Share on other sites More sharing options...
