Phyllosilicate | Structure & Facts | Britannica
phyllosilicate, compound with a structure in which silicate tetrahedrons (each consisting of a central silicon atom surrounded by four oxygen atoms at the corners of a tetrahedron) are arranged in sheets. Examples are talc and mica.

Phyllosilicates are sheet silicate minerals, formed by parallel sheets of silicate tetrahedra with Si 2 O 5 in a 2:5 ratio. Wikimedia Commons has media related to Phyllosilicates.
Phyllosilicates - Tulane University
The phyllosilicates, or sheet silicates, are an important group of minerals that includes the micas, chlorite, serpentine, talc, and the clay minerals.
Phyllosilicate - an overview | ScienceDirect Topics
Phyllosilicates form a large group of minerals that includes, among others, micas, smectites, and kaolinites. Their basic characteristic feature is the layered structure, and their formation can take place at the surface (e.g., in soils or sediment) or subsurface (diagenesis and hydrothermal alteration) (e.g., Meunier, 2005).
Silicate mineral - Wikipedia
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. [1][2][3] In mineralogy, silica (silicon dioxide, SiO2) is usually considered a …

Phyllosilicates - Encyclopedia.com
2018年5月8日 · Phyllosilicates are a group of minerals that are fundamentally composed of extended flat sheets of linked silicon-oxygen tetrahedra. Included in the phyllosilicate family are micas and clays. The name is derived from the Greek word phyllos, meaning leaf.
Phyllosilicate - Explanation, Examples, Structure and Groups
A phyllosilicate, which was previously known as a disilicate, is a compound with a structure in which the silicate tetrahedrons are arranged in sheets. Hence, they are also known as sheet silicates.
Phyllosilicates - GeoClassroom
The simplest phyllosilicates result from bonding one silicate layer to one octahedral layer. Because of this arrangement, we call these the 1:1 phyllosilicates. Kaolinite. The most important 1:1 phyllosilicate is the mineral kaolinite. The dioctahedral analogue is the serpentine mineral antigorite. 2:1 Phyllosilicate Structures.
Phyllosilicates - SpringerLink
Extensive lists of phyllosilicate compositions have been given by Deer, Howie, and Zussman (1962). Minerals with essentially the same chemical composition and the same layer structure but with different stacking arrangements are called “polytypes.”
