Clay minerals are sheet silicates.
The mineral mica is not a gemstone. It is not considered a precious mineral or gem. It is a valuable mineral that has a number of applications, and it is likely you have some mica in your home now. Mica is used in the electronics industry as an insulator beneath semiconductor packages when they are mounted on heat sinks in consumer (and other) electronic equipment.
The hardness of a mineral results from the type of chemical bond that exists in that mineral. Bonds vary according to the different elements involved, as well as the particular way in which those elements are combined. It's complicated.
An example of a foliated rock is slate. You can distinguish a foliated rock by the fact that the minerals line up in a sheet-like appearance. They are formed by pressure squeezing the minerals into alignment.
it is less known that there are minerals, like iron, that are trapped in the ice sheet which enter the oceans when ice melt occurs.
Yes and do u have the same work sheet as me page 68 and the packet is called what are metamorphic rocks?
it has 3 oxygen Adams
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)
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 :)
Isolated, Double chain, framework, single chain, and sheet
Sheet silicates are known as phyllosilicates or layer silicates. They consist of silicon and oxygen atoms - 2 silicon atoms for each 5 oxygen atoms. Kaolinite and serpentine are examples of sheet silicates. Kaolinite also contains hydrogen and aluminum atoms while serpentine contains hydrogen and magnesium atoms.
This gives a sheet silicate. Examples of minerals with this structure include kaolinite and talc.
Clay minerals structure themselves in sheets or layers, and are silicate minerals. This characteristic makes clay feel slippery when wet, as the flat individual mineral grains easily slide in a parallel fashion from one another.
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.

Mica minerals often appear in 'books' which are stacks of sheet-like mineral crystals.
