What else can I help you with?
What igneous rock contains mostly plagioclase feldspar and about 30 percent dark silicates?
A Diorite.
Why are the ferromagnesian silicates often dark dense metallic and magnetic?
Ferromagnesian silicates, which include minerals like olivine and pyroxene, contain significant amounts of iron and magnesium. These elements contribute to the minerals' darker colors and higher densities due to their heavier atomic weights. The presence of iron also imparts magnetic properties, as iron is a ferromagnetic element. Consequently, the combination of these factors leads to the characteristic dark, dense, and often magnetic nature of ferromagnesian silicates.
How do you extract silicates from its ore by aquaregia?
Silicates cannot be extracted from ore using aqua regia as it is not effective in dissolving silicates. Silicates are typically extracted using a different process, such as leaching with acids like hydrochloric acid or sulfuric acid, or by fusion with alkali compounds.
What are two big groups of minerals called?
Silicates and non-silicates are the two big groups of minerals. Silicates are the most abundant mineral group on Earth and contain silicon and oxygen, while non-silicates include minerals such as carbonates, sulfides, oxides, and native elements.
What minerals are on Neptune?
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 difference between dark and light silicate?
There are more differences between dark and light silicate than just their color. Light silicate is nonferromagnesian, while dark silicates are ferromagnesian. Light silicate is also lighter in gravity at about 2.7, and they usually contain bits of calcium, sodium, potassium and aluminum. Dark silicate usually has a heavier gravity between 3.2 and 3.6, and they are mostly comprised of magnesium and iron.
What igneous rock contains mostly plagioclase feldspar and about 30 percent dark silicates?
A Diorite.
Granite igneius rocks are light colored lower density than basltic rock high silics content?
Nonferromagnesian silicates. ferromagnesian silicates on the other hand are usually high density and dark in color.
What has the author I A Voinovitch written?
I. A. Voinovitch has written: 'L' analyse des silicates' -- subject(s): Silicates 'The analysis of silicates' -- subject(s): Silicates
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 most igneous rocks primarily composed of?
Igneous rocks are mostly made up of silicate minerals. These silicates are of two types, light and dark silicates. The dark silicates are also called ferromagnesian because of the presence of iron and magnesium in them. They include olivine, pyroxene, amphibole and biotite. The light-colored silicates include quartz, muscovite and feldspar. You can learn more about igneous rocks when you check the link.
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.
How do you extract silicates from its ore by aquaregia?
Silicates cannot be extracted from ore using aqua regia as it is not effective in dissolving silicates. Silicates are typically extracted using a different process, such as leaching with acids like hydrochloric acid or sulfuric acid, or by fusion with alkali compounds.
How many oxygen atoms are in single chain silicates?
Single chain silicates have a chemical formula of Al2SiO5. Therefore, there are a total of 5 oxygen atoms in single chain silicates.
What are two big groups of minerals called?
Silicates and non-silicates are the two big groups of minerals. Silicates are the most abundant mineral group on Earth and contain silicon and oxygen, while non-silicates include minerals such as carbonates, sulfides, oxides, and native elements.
