Hydroxide Mineral Goethite | Q?rius

In one example, limonite, a type of iron oxide hydroxide, substitutes itself in for pyrite, or iron sulfide, but the crystals are still shaped like the original pyrite. Geologists call the resulting mineral "limonite after pyrite." Another example of pseudomorphism occurs when quartz replaces crocidolite, a variety of riebeckite that is a source of asbestos fibers. The resulting solid mineral ...
