quarts, feldspar and mica
The most common mineral group that is broken into the subgroups of ferromagnesian and non-ferromagnesian is the silicate mineral group. Ferromagnesian silicates contain iron and/or magnesium, while non-ferromagnesian silicates do not contain these elements. Examples of ferromagnesian silicates include olivine and pyroxene, while examples of non-ferromagnesian silicates include feldspar and quartz.
Sheet silicates have a layered structure where silica tetrahedra are arranged in sheets with cations between the layers, while framework silicates have a three-dimensional network of silica tetrahedra connected in all directions. Sheet silicates have weaker bonds between layers, allowing for easier cleavage and flexibility, while framework silicates have stronger bonds, resulting in a more rigid structure.
Isolated tetrahedra silicates do not link with other silicon or oxygen atoms Ring Silicates form by sharing oxygen atoms Single Chain Silicates form a chain when sharing oxygen atoms Double Chain Silicates form when two or more single chains of tetrahedra bond to each other Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra Framework Silicates form when each tetrahedron is bonded to four other tetrahedras :)
Minerals that contain the elements silicon and oxygen are called silicates. Silicates are the largest and most diverse class of minerals, making up over 90% of the Earth's crust. Examples of common silicate minerals include quartz, feldspar, and mica.
A structural type of silicate mineral in which flat sheets are formed by the sharing of three of the four oxygen atoms in each tetrahedron with neighboring tetrahedrons. Also known as layer silicate; sheet mineral; sheet silicate.
Both feldspar and mica are silicates.
Silicates, oxides, and sulfides.

i really don't know but i need help

Spain, Italy, and Germany are three examples.

Minerals containing silicon, oxygen, and one or more elements are called silicates. Silicates are the largest and most important group of minerals, making up approximately 90% of Earth’s crust. Examples of silicate minerals include quartz, feldspar, and mica.
