Does the smallest group of rock forming minerals consist of silicates?
No. Silicates are the largest group of rock forming minerals.
What is rhyolitic composition?
It contains about 70% Silica(SiO2)Added:Rhyolite, a gost town town in South-Nevada, is named for rhyolite, an igneous rock composed of light-colored silicates, usually buff to pink and occasionally light gray. It belongs to the same rock class, felsic, as granite but is much less common.
Is hornblend a mineral?
Yes it is. Hornblende under chain silicates group. Diagram below shows which group and sub-groups it belongs to:CHAIN SILICATES1. Pyroxenes2. AmphibolesHornblende (is here)OxyhornblendeEtc.3. Pyroxenoids4. Other Chain Silicates
What are mineral salts proper name?
They can be silicates or vanadates, nitrates or chlorides, carbonates or arsenides etc.
What mineral family is talc a part of?
Talc is one of a family of insoluble mineral magnesium silicates.
What is the difference ferromagnesian and non-ferromagnesian silicates?
Ferromagnesian silicates contain iron and magnesium in their composition, which gives them a dark color and high density. Non-ferromagnesian silicates do not contain iron and magnesium, resulting in lighter colors and lower densities. Ferromagnesian silicates tend to be denser and have higher melting points compared to non-ferromagnesian silicates.
What is the formula of ash?
Generally ash is a mixture of oxides and silicates; the composition depends on the burned material.
What property is used to classify minerals into groups like silicates?
The property used to classify minerals into groups like silicates is their chemical composition. Silicates are minerals composed of silicon and oxygen, and they make up the largest group of minerals found in the Earth's crust. Minerals are categorized by their chemical composition, crystal structure, and physical properties.
What is a garnet composition?
Garnets are double silicates of (Ca, Mg, Mn or Fe2) and (Al, Fe3 or Cr).
What is composition of clay?
Clays are hydrous aluminum silicates with trace amounts of other elements like calcium, iron, and magnesium.
What are the three groupings of minerals?
Minerals are grouped by their chemical composition. There are more than 3 groups of minerals including. Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups. Silicates are definitely at the top of the list.
What has the author I A Voinovitch written?

What are the two major mineral grouped?
Silicates and non-silicates.
What are the two most common kinds of minerals?
Silicates and non-silicates.
What are the non ferromagnesian silicates?
Non-ferromagnesian silicates are silicate minerals that do not contain iron (Fe) or magnesium (Mg) in their chemical composition. They include minerals such as quartz, feldspar, muscovite, and kaolinite. These minerals play important roles in various geological processes and are commonly found in rocks like granite, sandstone, and clay.

How do sheet silicates differ from framework silicates?
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.
