.....Styria is part of the ancient Noricum.
As to the iron oar to be found there:

....last part of the info (marked with an asteriks):
(Roughly translated, of course :wink: )
"Remark for oar-emphatics:
Local oar deposits differ from imported oar mainly by their chemical composition. As opposed to imported oar, which consist of Magnetite (Fe3O4) and Hamatite (Fe2O3) throughout, local oar deposits contain Siderit (FeCO3) with a certain portion of carbon. [Ed.: ….and in a certain way of shape and distribution as far as I recall from school, later findings show that some iron oar samples from the Alps even contain Fe3Si (Gupeiit) und Fe5Si3 (Xifengit) which raised the question of a possible meteorite impact in the Chiemgau during ancient times.] Furthermore local iron deposits do contain a proportionally large part of slag-forming ingredients like Calcium (Ca), Silicium (Si) and Magnesium (Mg). This leads to a relatively minor content of pure iron in the local deposits (33%). Imported iron oars do have an iron content up to 66% by comparison.â€
