Call number:
D15 (2)
Classification:
Carbonates
Translated title:
Siderite
Place of origin:
Freiberg / Saxony, Germany
Depositional environment:
Most often found in bedded sedimentary deposits with a biological component, with shales, clays and coal beds - suggesting that the siderite is biogenically created under low-oxygen and low-Ph conditions. It is also found in metamorphosed sedimentary rocks as more massively crystalline material, as a primary gangue mineral in hydrothermal deposits, and in pegmatites, including nepheline syenite pegamtites; as bog deposits.
