For the "terrestrial phase", minerals-in-meteorites collector here are links to lawrencite and akaganeite. There is even a printable collection card at the bottom of each description.(as are taenite and kamacite under their descriptions) Akaganeite: <http://webmineral.com/data/Akaganeite.shtml> Lawrencite: <http://webmineral.com/data/Lawrencite.shtml>
Akaganeite is a chlorinated iron hydrite which is the alteration product [Fe+++(O,OH,Cl)] derived from the former in the presence of moisture. Those that claim to literally watch their Campos rust away into flakes aren't too far off. The Lawrencite Hydrochloric duo moves into pores and cracks where forming akaganeite expands and flakes away rotten layers.
