Siderite Value, Price, and Jewelry Information

What is Siderite? Siderite forms three solid-state solution series. It's the iron (Fe) analogue in a series with manganese (Mn) dominant rhodochrosite. It also forms the Fe-end of a series with zinc (Zn) dominant smithsonite, as well as with magnesium (Mg) dominant magnesite. Siderite has been used as an iron ore and for steel production.

IMPERIAL VALLEY CONCRETIONS

Perhaps the most unusual concretion nuclei are found in a modern coastal salt marsh in England. Siderite (FeCO 3) concretions in the marsh formed around World-War-II era military shells, bombs, and associated shrapnel, including some large unexploded shells (Al-Agha et al., 1995). A British geologist studying these concretions realized this ...
