Duane Posted October 27, 2016 Share Posted October 27, 2016 What is this? Petrified frog eggs? The spot are dark green! Link to comment Share on other sites More sharing options...
tmaier Posted October 27, 2016 Share Posted October 27, 2016 It's not a fossil of a life form, because soft tissues don't petrify that way (normally). It is some green mineral concretions that have formed in a matrix of .... mmmm.... quarzite or calcite or some type of white matrix. The center of each concretion has a spherical depletion zone around it, where the mineral has influenced the surrounding zone, either pulling mineral out of that area or altering it some way to produce that light colored "egg" look around it. Green might be copper or iron mineral. The rock also has an orange hue to it, so that makes me think there is some iron in it, and the specks might be a concentration of this iron mineral. 1 Link to comment Share on other sites More sharing options...
caldigger Posted October 27, 2016 Share Posted October 27, 2016 It looks like an Oolitic rock. We have a beach near by that is well known for Oolite that looks just like yours. Very light colored circles with dark mineral in the center. Link to comment Share on other sites More sharing options...

Duane Posted October 28, 2016 Author Share Posted October 28, 2016 (edited) Thanks everyone! Very interesting!...I thought it may have been a bird egg until I looked with a magnify glass, each dot has what looked like tails. With a flashlight at certain angles it's clear as glass, with littles orbs! I think when I squeezed it, it actually seemed to make lines in it...so I thought frog eggs in amber? It feels like a rock so perhaps it is just hardened minerals of sorts! Thank you!!! Edited October 28, 2016 by Duane Sorry I forgot to specify, I'm in the south cariboo, British Columbia, the "rock" was found at the base of a tree. It is very dry here, and it was found on very high terrain! Link to comment Share on other sites More sharing options...

I've been looking at these oolites and they are the closest thing I've found to my "rock"....but are oolites completely clear throughout? The "eggs" in my pic appear to be 3D Link to comment Share on other sites More sharing options...
Duane Posted October 28, 2016 Author Share Posted October 28, 2016 There is a crack in it that makes the orange very dark.If I take pics at other angles with a flashlight, it's too bright to take a pic,..it's that clear throughout Link to comment Share on other sites More sharing options...

Hardness would be useful to know - it looks like chalcedony of some sort which would be too hard to scratch with a knife. 1 Tarquin Link to comment Share on other sites More sharing options...
