Amphibole, an important group of generally dark-colored rock-forming inosilicate minerals, composed of double chain SiO4 tetrahedra, linked at the vertices and generally containing ions of iron and/or magnesium in their structures. (e.g. asbestos)

Which silicate mineral group has a double chain silicate?

A silicate mineral that shares it's oxygen atom with another silica tetrahedron, forming a chain of tetrahedra. Single chain silicates include a group called the pyroxenes.


What are the 6 main crystalline structures of silicate minerals?

The six main crystalline structures of silicate minerals are isolated tetrahedra, single chain, double chain, sheet, framework, and ring structures. Each structure is based on how the silicate tetrahedra are arranged and linked together in the mineral's crystal lattice.

What is the result when two single chains of tetrahedra bond to each other?

When two single chains of tetrahedra bond to each other, they form a double chain structure. This arrangement creates a stronger and more stable crystal lattice compared to the individual chains.


Hornblende has what type of silicate structure?

Hornblende has a double chain silicate structure. This structure consists of pairs of linked tetrahedra that form continuous chains in two dimensions.

What are main types of silicate structures?

The main types of silicate structures are isolated tetrahedra, single chains, double chains, sheets, and three-dimensional frameworks. These structures are based on the arrangement and connections of silicon-oxygen tetrahedra in minerals.


What do all silicate minerals have in common?

All silicate minerals are composed of silicon and oxygen atoms arranged in a tetrahedral structure. These tetrahedra can be linked together in various formations to create different silicate mineral groups, such as sheet silicates, framework silicates, and chain silicates. Silicate minerals are the most abundant group of minerals in the Earth's crust.


What are the four major silicate groups?

island silicates (0 shared oxygen) disilicates (1 shared) single chain silictes (2 shared) ring silicates (aka double chain silicates) (2 or 3 shared) sheet silicates (3 shared) framework silicates (4 shared)


Hornblende and the other amphiboles have what type of silicate structure?

Hornblende and other amphiboles have a double chain silicate structure, where silicon-oxygen tetrahedra are connected in double chains linked by other cations like aluminum, magnesium, and iron ions. This structure gives amphiboles their distinct prismatic shape and cleavage properties.
