How is it possible for magma to have a higher silica content than the rock from which it formed?

Magma could have higher silica content than its parent rock, if during melting or movement it is gets in contact with silicic country rocks and absorbs them. This is reffered to as Assimillation.

What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
Does gabbro have a higher silica content than granite?
Gabbro has less silica than granite.
How does granite differ from gabbro in coloring and silica content?
Granite is lighter in color and higher in silicate mineral content.
What mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
What is the relationship between silica content and viscosity?
magma that has more silica is more viscous

What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
Does gabbro have a higher silica content than granite?
Gabbro has less silica than granite.
What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
How does granite differ from gabbro in coloring and silica content?
Granite is lighter in color and higher in silicate mineral content.
What affects the speed of lava flows?
The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).
What does silica content?
Any metrial or thing which containts silica in it is call silica content..
Which property of magma will change the viscosity?
Silica content determines viscosity. The higher the silica content the more viscous (slower moving). Ultramafic <45% silica Least viscous Mafic 45-52% Silica Intermediate 53-65% Silica Felsic >65% Silica Highly viscous
What does silica content mean?
Any metrial or thing which containts silica in it is call silica content..
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
