Phyllosilicate Specimens Gallery M&W Minerals

Phyllosilicates Gallery

Phyllosilicate are composed of rings of SiO₄ tetrahedrons joined together by the Oxygen ions with other tetrahedrons in a two dimensional plane. Because of the shared Oxygen, the ratio of O to Si is less than 4 to 1. There are a large number of members in this class of Silicates.

This includes the Mica group (Muscovite, Lepidolite, Biotite, Phlogopite and others) the Clay group (Talc, Kaolinite, Montmorillonite, Pyrophyllite, Vermiculite, Glauconite and others) the Chlorite sub-group of clays (Clinochlore, Cookeite, indeterminant Chlorite and others), Apophyllite, Gyrolite, Prehnite, Chrysocolla, Cavansite, Ajoite, Papagoite, Carletonite, the Serpentine group (inderminate Serpentine, Antigorite, Lizardite and others) and still others
