• Iddingsite - Wikipedia

    en.wikipedia.org/wiki/Iddingsite Iddingsite is a microcrystalline rock that is derived from alteration of olivine.It is usually studied as a mineral, and consists of a mixture of remnant olivine, clay minerals, iron oxides and ferrihydrites.Debates over iddingsite's non-definite crystal structure caused it to be de-listed as an official mineral by the IMA; thus it is properly referred to as a rock.
