Much Limonite, especially the fibrous type, is either Goethite or alter ed Goethite that absorbed water in its chemical structure. Limonite commonly forms as a pseudomorph over other minerals, especially Pyrite, Marcasite and Siderite.
Based on their structures and chemical compositions, the clay minerals can be divided in to three main classes: 1  The kandites based on a structure similar to Kaolinite. 2  The smectites based on a structure similar to Pyrophyllite. 3  The illites based on a structure similar to Muscovite.
