Thanked: 3164Hatzicho - that ordovician rainbow-hued thuringian is a fantastic looking specimen.
With my mystery paddle hone the red-brown/yellow-brown/orange spots seem to be due to a high ferric oxide content.
What do you ascribe the rainbow hues to in your stone? I know that oil comes from some ordovician strata - do you think it could related to that?
Regards,
Neil
