Saul R W 741 Posted July 19, 2018 Share Posted July 19, 2018 I replied to the same rock in another thread a few minutes ago. 'S'not a meteorite. I think it belongs in the Rocks, Minerals and Fossils section. 1 Quote Link to post Share on other sites
Graham 2 Posted July 19, 2018 Author Share Posted July 19, 2018 Could anyone please help identify this please 1 Quote Link to post Share on other sites
Saul R W 741 Posted July 19, 2018 Share Posted July 19, 2018 My color perception isn't great (too many head-first dives off cliffs with homemade parachutes as a kid, trying to hang glide), but the pattern is strikingly similar to star emerald, maybe in a schist instead of granite peg? Definitely some nice radial crystal groups. Neat rock. I want one. Quote Link to post Share on other sites
chrisski 847 Posted July 19, 2018 Share Posted July 19, 2018 Looks in a way like brain coral. Maybe petrified? 1 Quote Link to post Share on other sites
Mikestang 925 Posted July 19, 2018 Share Posted July 19, 2018 Looks like a fossil maybe? Certainly not a meteorite. 1 Quote Link to post Share on other sites
Graham 2 Posted July 19, 2018 Author Share Posted July 19, 2018 Thanks it defo not coral but thanks for replying bk Quote Link to post Share on other sites
Graham 2 Posted July 19, 2018 Author Share Posted July 19, 2018 Is there a way of me finding out what it is? Quote Link to post Share on other sites
Saul R W 741 Posted July 19, 2018 Share Posted July 19, 2018 What area it was found would be the first thing I'd ask to narrow down possibilities. Check hardness and streak. And crystal shape and color. 1 Quote Link to post Share on other sites
Graham 2 Posted July 19, 2018 Author Share Posted July 19, 2018 Come from a chalk quary in East Sussex uk that’s all I know Quote Link to post Share on other sites
Morlock 1,690 Posted July 19, 2018 Share Posted July 19, 2018 Do a streak test on it. https://geology.com/minerals/streak-test.shtml 2 Quote Link to post Share on other sites

Au Seeker 3,156 Posted July 19, 2018 Share Posted July 19, 2018 Graham. I have merged 2 of your topics onto one. Quote Link to post Share on other sites
Morlock 1,690 Posted July 19, 2018 Share Posted July 19, 2018 Maybe goethite? 1 Quote Link to post Share on other sites
Hole Digger 25 Posted July 19, 2018 Share Posted July 19, 2018 The second picture looks kind of like a pyrite sun. Quote Link to post Share on other sites
4meter 200 Posted July 20, 2018 Share Posted July 20, 2018 It s defiantly a Pyrite nodule. Do a streak and hardness test on a fresh "metallic" exposed portion, not on the dull yellowing-brown surface, to confirm for yourself. Quote Link to post Share on other sites
Randall 114 Posted July 20, 2018 Share Posted July 20, 2018 How many pieces of this did you find? The first photo looks like a half piece and the pic further down looks complete...fully round? Show us a cross-section pic of the first photo if you can! Quote Link to post Share on other sites
Randall 114 Posted July 20, 2018 Share Posted July 20, 2018 Just read some information regarding England's chalk quarries. Chalk's main component is calcium carbonate which is a form of limestone. The article went on to say that MANY fossilized marine examples can and are found in England's chalk quarries.! Not saying for sure that is what you have but you may want to google England's chalk quarries and take a look. Quote Link to post Share on other sites
Morlock 1,690 Posted July 20, 2018 Share Posted July 20, 2018 I don't think it's a fossil. The first thing that came to my mind was a goethite radial cluster that's been badly weathered. I could be wrong so we'll have to wait to hear what the steak looks like. 1 Quote Link to post Share on other sites

Needs to be tested to be certain, but it's the direction I'm leaning. 3 Quote Link to post Share on other sites
d_day 342 Posted July 20, 2018 Share Posted July 20, 2018 Here's a pyrite module in situ. 2 Quote Link to post Share on other sites
d_day 342 Posted July 20, 2018 Share Posted July 20, 2018 And here's one broken open. Nowhere near as weathered as the OP's rock. 4 Quote Link to post Share on other sites
Randall 114 Posted July 21, 2018 Share Posted July 21, 2018 Hey I'm certainly not disagreeing with you guys cause what I read also stated different minerals can also be found! Those last two photos look pretty convincing Quote Link to post Share on other sites
Bedrock Bob 4,021 Posted July 21, 2018 Share Posted July 21, 2018 It is an iron concretion. Like a shaman stone or a moqui marble. A fairly common oddity. Plenty of photos on the internet to compare it with. They are spherical but often break in pieces showing a radial or concentric pattern. It is a sweet rock. Go back and find a matched pair of complete spherical concretions and you will have a set of "shaman stones". Very good luck! Quote Link to post Share on other sites
