Quartz is made up of silicon and oxygen (SiO2) and has a distinct crystal structure. It is one of the most common minerals on Earth and has a wide range of colors and varieties. Unlike other silicate minerals, quartz is highly resistant to weathering and is very hard (7 on the Mohs scale).

How many silicate minerals are present in Mohrs hardness scale?
There are numerous silicate minerals present in Mohs hardness scale. Some examples include quartz (hardness of 7), feldspar (hardness of 6), and amphibole (hardness varies based on composition). Each of these minerals falls at different points on the scale, indicating their relative hardness compared to other minerals.
Is iron ore a silicate mineral?
No, iron ore is not a silicate mineral. Iron ore is typically composed of iron oxides, such as hematite and magnetite, which are not silicate minerals. Silicate minerals are minerals that contain silica, oxygen, and other elements like silicon and aluminum.
Do a non silicate minerals contain oxygen?
Yes, non-silicate minerals can still contain oxygen. For example, carbonates such as calcite and dolomite are non-silicate minerals that contain oxygen along with carbon and other elements.
what is the mineral contain silicon oxygen and usually one or more other other element?
The mineral containing silicon, oxygen, and usually one or more other elements is called silicate. Silicates are the largest and most important class of minerals, making up over 90% of Earth's crust. Examples of silicate minerals include quartz, feldspar, and mica.
When each tetrahedron shares three of its oxygen atoms with other tetrahedra silicates form what?
When each tetrahedron shares three of its oxygen atoms with other tetrahedra, a framework silicate structure is formed. This structure results in a three-dimensional network of interconnected tetrahedra, giving rise to minerals such as quartz and feldspar.
What are silicate minerals?
Silicate minerals are the most common type of minerals found in the Earth's crust. They are composed of silicon and oxygen in combination with various other elements. Examples include quartz, feldspar, and mica.
If all silicates contain silicon and oxygen why are there so many different kinds of silicate minerals?
Silicate minerals have diverse structures due to variations in how silicon and oxygen atoms are arranged with other elements in their crystal lattice. This leads to a wide range of physical and chemical properties in silicate minerals, resulting in different types such as quartz, feldspar, mica, and amphibole.
Is quartz a sillicate?
It is the absolute silicate. All other silicates have greater amounts of silicon and oxygen along with other minerals.
What are minerals that contain oxygen and silicon?
They are classified as silicates, one of the more common being the mineral quartz which is composed only of the elements silicon and oxygen (SiO2). Other silicate minerals may include one or more other elements as well in their chemical formula.
What is the most common form of minerals?
Silicate minerals are the most common form of minerals on Earth. They are composed of silicon and oxygen, along with other elements. Examples include quartz, feldspar, and mica.
Major family of rock forming minerals?
The major family of rock-forming minerals is the silicate minerals. These minerals are made up of silicon and oxygen atoms, often combined with other elements like aluminum, iron, and magnesium. Some examples of silicate minerals include quartz, feldspar, and mica.
What minerals are most common in detrital sedimentary rocks and why are these minerals so abundant?
We know silicate minerals are the most abundant in detrital sedimentary rocks.Quartzv is a tectosilicate mineral.So quartz is the most abundant and other silicate minerals are also very common in these rocks.
Whats the definition for silicate minerals?
Silicate minerals are a class of minerals that make up over 90% of the Earth's crust. They contain silicon and oxygen as their primary components, typically combined with other elements like aluminum, iron, magnesium, or calcium. Silicate minerals are characterized by their tetrahedral structure, where one silicon atom is surrounded by four oxygen atoms.
How many silicate minerals are present in Mohrs hardness scale?
There are numerous silicate minerals present in Mohs hardness scale. Some examples include quartz (hardness of 7), feldspar (hardness of 6), and amphibole (hardness varies based on composition). Each of these minerals falls at different points on the scale, indicating their relative hardness compared to other minerals.
What are the SILICATE group of minerals?
Neso-, soro-, cyclo-, ino-, phyllo- and tectosilicates are all the groups of silicate minerals.
What are some minerals that have quartz in them?
Quartz is a mineral. No other minerals contain quartz.
All silicate minerals contain the elements?
silicon and oxygen apex :p
