Double chain silicate mineral?
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.
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 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 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.
How would you differentiate amphibole from olivine?
Amphibole and olivine can be differentiated based on their mineral structure and composition. Amphibole is a complex silicate mineral with a double-chain structure, typically containing hydroxyl groups (OH) and exhibiting a range of colors, while olivine is a simple silicate with a single-chain structure, primarily composed of magnesium and iron silicate (Mg, Fe)2SiO4. Additionally, olivine commonly appears green and has a glassy luster, whereas amphibole can exhibit a more varied color palette and often has a more fibrous or prismatic habit. Lastly, amphibole has a lower hardness than olivine, making it easier to scratch.
Which are nonsillicate crystalline structures?
a double chain silicate is
When two single chain of tetrahedra bond to each other the result is?
double chain silicate
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.
Minerals of this family tend to form long needlelike crystals?
The mineral family that tends to form long needlelike crystals is the amphibole group. Examples of minerals in this group include hornblende and tremolite. These minerals are silicate minerals with a double chain structure, which contributes to their characteristic needlelike crystal habit.
What is the result of two single chains of tetrahedra bond to each other?
double chain silicate
