The iron can be replaced by other minerals:

CALCIUMSIDERITA: (Fe, Ca) CO3.

MAGNIOSIDERITA: (Fe, Mg) CO3 over 40% of Mg.

MANGANOSIDERITA: (Fe, Mn) CO3, with 10-30% Mn.

OLIGONITA: (Fe, Mn) CO3, ore 40% Mn.

SIDEROPLESITA: (Fe, Mg) CO3 10-30% Mg.

SPHEROSIDERITA botryoidal  of habit.

ZINCOSIDERITA (Zn, Ca) CO3.

MYTHOLOGY: The siderite was discovered in 1845, and was named, that is composed of iron, which in Greek is "sidereal". I could be found in clusters of crystals. This mineral can be found in space, for example, the moon contains this stone as meteorites. The synonyms of siderite in Spanish are: aerosiderita, bemmelenita, chalybita, gyrita, pelosiderita or thomaíta.
