All magma contains SiO2. What affects magma is the amount of SiO2 in it. Magma is classified into four basic groups that can be determined by how much silica it contains by weight.
Felsic: >63% SiO2
Untermediate: 52-63% SiO2
Mafic: 45-52%SiO2
Ultramafic: <45% SiO2
This spectrum is a basic guide to silicate magmas, which encompass that vast majority of magma. One exception is rare carbonatite magma, which is carbonate rather than silicate based, and even that contains some SiO2.

What is the composition of magma of popocatepetl?
A mixture of dacite (65wt% SiO2) and basaltic andesite (53wt% SiO2).
What are three main types of magma what factor determines these classification?
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.

How much silica is in the magma at mt lamington?
Mt. Lamington, located in Papua New Guinea, is primarily composed of andesitic magma, which typically contains around 57-63% silica (SiO2). This high silica content contributes to the volcano's explosive eruptions, as andesitic magma is more viscous compared to basaltic magma. The specific silica content can vary depending on the particular eruption and the composition of the magma chamber at the time.
What is the most abundant compound found in magma?
The most abundant compound found in magma is silica (SiO2), which is commonly found in the form of quartz and feldspar minerals. Silica content plays a key role in determining the viscosity and behavior of magma.

What is the Common material that contains fused SiO2?
glass is the most common material containing fused SiO2
What is chemical formula of quartz?
The chemical formula for quartz is SiO2, which means it contains one silicon atom and two oxygen atoms per molecule.

What mineral contains mostly silicone and oxygen?
Quartz (SiO2).
How do you determine the number of silicon atoms in 4SiO2?
4SiO2 means SiO2 + SiO2 + SiO2 + SiO2 The '4 'tells you that there are four seprate molecules of SiO2 So there will be 4 silicon atoms in 4SiO2 SiO2 also contains 2 oxygen atoms. So overall there will be 4 x 2 = 8 oxygen atoms. SiO2 is silicon dioxide ; sand that you find on a beach. It does form large crystal lattice by a loose combination through the oxygen atoms.
What type of rock contains lava or magma?
The type of rock that contains lava or magma is an igneous rock.

The most abundant compound found in magma is silica (SiO2), which is commonly found in the form of quartz and feldspar minerals. Silica content plays a key role in determining the viscosity and behavior of magma.
What elements combined makes sand?
Sand essentially contains silicon dioxide (SiO2) and oxygen.
