A difficult piece to describe, as there are no real comparisons to be found.
We found this specimen in 2002 in the amphibolite quarry on the Terpetzen, SO Saualpe.
The determination was and is not easy. The flaky crystals and the color indicate an iron mineral.
CaFe(CO3)2
Anchorage or ferruginous dolomite The exact designation depends on the iron content. Mixed crystals from the carbonate series. The crystals sit on a very heavy brown ironstone. Similar pieces were also found in Hüttenberg, which is also on the Saualpe, only further north and the iron deposits of this quarry are probably connected to the ore deposits of Hüttenberg, where the famous Norian iron was mined over 2,000 years ago.
The crystals are highly lustrous and have a pearly and silky sheen. The color is brown-yellowish light orange.
Unique level.
