Description
1) A yellowish-brown iron ore composed of iron carbonate. Siderite, also called chalybite, is mined in England, Austria, Czech Republic, France, Italy, Greenland, Australia, Brazil, Bolivia, and the U.S. It has a specific gravity of 3.83-3.88 along with an uneven fracture, pearly luster, and pale yellow streak.
2) A metallic Meteorite composed primarily of Iron and Nickel.
Synonyms and Related Terms
