Could you please help me identify the rock found commonly near many of the ancient Greek foundations and rubbles? This one was at the base of Poseidon's temple.

White in colour with a smooth texture like marble.

Dropped pin near Laurium (Port Sounion), Greece

I believe it was transported to the site during the construction phase.

  • $\begingroup$ You are welcome. Questions are allowed if you give us some geological info we need. I returned home and I orderer the body of the question. You can accept my edition if you wish. If you return, please, leave us a picture of the temple or the rests where you found this marble! looks like one of those nice construction marbles we have at the Mediterranian. It can be a marble sensu stricto (a metamorphic calcite rock) or a marble sensu lacto (a sedimentary white calcite rock, we call that sedimentary limestone), probably not metamorphic $\endgroup$ – user12525 Oct 20 '18 at 20:01
  • $\begingroup$ Limestones are so common because Mediterranean was a Thetys type ocean with lots of carbonated shallow platforms. en.wikipedia.org/wiki/Tethys_Ocean $\endgroup$ – user12525 Oct 20 '18 at 20:06

    $\begingroup$ Is this the only picture you have? It's not in focus. And you probably can't go back there to investigate it... $\endgroup$ – Jan Doggen Oct 21 '18 at 10:51

    $\begingroup$ So, looking at the "dropped pin" in Google Maps we see this is near the ruins of the Temple of Poseidon which would have been easy to include in the original question. I don't think you'd be allowed to do an acid test so this question is probably better asked on History SE with other archaeology questions. $\endgroup$ – Spencer Oct 21 '18 at 13:33
