Formula gives the approximate bulk composition. Later studies (Smith et al 1987) found progressive changes of the bulk composition during alteration, with final stages approaching the composition of pure goethite (FeOOH).
Hardness:3
Name:
Named by Andrew Cowper Lawson in 1893 for one of the great American petrologists Joseph Paxson Iddings [January 21, 1857 Baltimore, Maryland - September 8, 1920]. He was with the United States Geological Survey and later professor at the University of Chicago. He was one of the great petrologists of his era.


A common alteration product of Olivine, often observed in thin sections.

A mixture of clay minerals (chlorite group, smectite group), iron oxides and ferrihydrides.
