How does silica from molten material affect the color of igneous rock?

∙ 14y ago
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.

Is silica intrusive or extrusive?
The terms intrusive and extrusive apply to the formation of igneous rocks. Silica is a chemical component of a wide variety of minerals found in many types of igneous, metamorphic, and sedimentary rock. All igneous rocks, both intrusive and extrusive, contain silica.
What is the name of a silica rick igneous rock?
volcanic rocks
What are the main colors of igneous rocks?
Igneous rocks come in a variety of colors. However the main colors are white, black, gray, greenand pink.

How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
How silica content of molten material affects the color of igneous rocks?
The more silica contained in a rock, the lighter in color it will be.
How the silica content of Molten material affects the color of igneous rock's?
The more silica contained in a rock, the lighter in color it will be.
How does the silica content of molten material effects the color of igneous rock?
Silica in molten material tends to crystallise as quartz, which is white or mostly pale in colour. So felsic rocks (from silica-rich magma) tend to be pale, while mafic rocks (from silica-poor magma) tend to be dark in colour.
How the silica content of molten affects the color of igneous rocks?
The more silica contained in a rock, the lighter in color it will be.
Explain how the silica content of molten material affects the color of igneous rocks?
Silica in molten material tends to crystallise as quartz, which is white or mostly pale in colour. So felsic rocks (from silica-rich magma) tend to be pale, while mafic rocks (from silica-poor magma) tend to be dark in colour.
Which of the igneous rock types has the lowest silica content?
Ultramafic igneous rock contains the least silica.
What color will igneous rock with high levels of silica be?
An igneous rock with a high level of silica will have a light color.
What igneous rock family contains the highest proportion of silica?
Felsic igneous rock contains the highest proportion of silica. Granites are felsic igneous rocks.
What is granite bedrock?
Bedrock is the rock that underlies the soil and sediment of an area. Granite is a type of igneous rock that forms when silica-rich molten rock cools and solidifies underground.
An example of an igneous rock low in silica is granite?
False. Basalt would be an example of an igneous rock with a low silica content.
What are the terms felsic and mafic used by geologists to describe?
They are descriptive terms as to the relative silica content of igneous rocks. Igneous rock which is high in silica is referred to as felsic. Igneous rock which is relatively low in silica is referred to as mafic.
