Explain how the silica content of molten material affects the color of igneous rocks?
Wiki User
∙ 9y ago
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.

Igneous rocks high in silicate content are generally lighter in color than are the mafic (low in silicate) rocks.

∙ 8y ago-The magma that is high in silica usually forms light-colored rocks such as granite.
-the lava that is low in silica usually forms in dark-colored rocks such as basalt.

∙ 9y agoThe 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.

What is an igneous rocks color determined by?

Which rocks have a name that means''fire''?
It would be a ingeous rock.
Where was the eroded material from the shield deposited and what did this material become?
igneous rock and it became sand
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.
An igneous rock with a low silica content that flows easily?
No igneous rock flows easily. However, basaltic lava can flow easily, has a relatively low silica content, and turns into basalt, the rock, when solidified.
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 does silica from molten material affect the color of igneous rock?
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.
