    www.sciencedirect.com/topics/earth-and-planetary-sciences/berthierine Berthierine, (FeMg) 3-x(Fe 3 Al)x(Si 2 -x Al x)O 5 (OH) 4, is the FeII-rich member of the serpentine subgroup most commonly encountered in unmetamoprhosed sedimentary rocks and odinite is its FeIII-rich counterpart found (so far) in Eocene and younger sediments.
  • Serpentine subgroup - Wikipedia

    en.wikipedia.org/wiki/Berthierine The serpentine subgroup (part of the kaolinite-serpentine group) are greenish, brownish, or spotted minerals commonly found in serpentinite rocks. They are used as a source of magnesium and asbestos, and as a decorative stone. The name is thought to come from the greenish color being that of a serpent. The serpentine group describes a group of common rock-forming hydrous magnesium iron ...

    en.wikipedia.org/wiki/Chamosite Chamosite is the Fe 2+ end member of the chlorite group.A hydrous aluminium silicate of iron, which is produced in an environment of low to moderate grade of metamorphosed iron deposits, as gray or black crystals in oolitic iron ore. Like other chlorites, it is a product of the hydrothermal alteration of pyroxenes, amphiboles and biotite in igneous rock.The composition of chlorite is often ...
