Metal embedded in sedimentary rock, please help with ID


Recommended Posts

Hi, thanks for you replies guys,

Actually the stone was just a boulder picked up from the sea shore, and split apart using the hammer. The boulder is a limestone,

I was just curious, what was the process that created that. Regarding the fossils, i found some, but not that much, I live in the area with no rocks and mountains, only boulders

Thanks

Motnis,

First let me Welcome you to the forum!

Some fossils can be made entirely of pyrite, such as the ammonite pictured below, I really don't know that much about fossils, etc., but I'm very good at finding information on the internet, such as the picture below, here's a link to the webpage where the picture was found, the webpage explains what pyrite is, and how pyrite forms in sedimentary rock such as the limestone you found.

Here a link to more pictures of fossils made of pyrite..

Here's a good read about fossils made of pyrite from China.

Hello Admin,

As I admitted before, my English might be weak.

Thank you for sending me the links!, but unfortunately after couple hours of reading, I realized, that there is no fossil in my limestone, so.... please explain me, why do you explain a pyrite mine in the limestone by showing me the fossils? Is this a common practise to explain all kind of things using fossils (I'm new here, so please be forgiving).

Thanks

Motnis

Motnis,

I'm sorry I forgot the post the first link :grr01: where I found the picture of the pyrite ammonite, and where it explains how pyrite forms in rock, I added the link to my reply above, and here it is again.

http://www.discoveringfossils.co.uk/pyrite_formation_fossils.htm

I gave you the information to explain that even though you do not have a fossil in the limestone, but you do have some pyrite, it maybe possible that if you did find a fossil in some of the limestone from the same location, the fossil could be made of pyrite, I also posted the first link because it had the information on how pyrite is formed in stone which was a question you asked, this process would be the same for a piece of pyrite or a fossil made of pyrite.

All the other links I thought maybe of some interest too you.
