Is this stromatolite?

[CornelDumitru]

Hi!

 

Is this a stromatolite?

I picked up this rock on the premises of the Teleajen oil refinery in Prahova county, Romania.

I have seen a chert wedge in a limestone boulder once upon a time, but this stone is different.

It has layers of chert and carbonate, right?

I grinded and polished the stone.

 

 

 

 

 

 

 

Here is a close-up from the carbonatic area (fizzles with acid): 

 

Any idea how old are these rocks when found in S-E Europe?

Thanks!

The geology of the area is Miocene/Pliocene 23-2.4mya. The stone does not look like a stromatolite.

Agreed. I don't know what it is, but I'm pretty sure it isn't a stromatolite. They typically are layered more like that flakey pastry.

I don't see any indications of it being  stromatolite. I concur with your description, and conclude that it is just a rock

Agree with the others above.
