An igneous rock's color is mainly determined by its silica content.
granitic igneous rocks are light colored because of a lower density than basaltic rocks
Its color
Igneous rocks that are medium colored and have no silica are called mafic rocks. They are mainly composed of magnesium and iron.
Light colored igneous rocks have a higher silica content and are known as felsic rocks. They have a lower density and are more common in continental crust. These rocks tend to be rich in minerals like quartz, potassium feldspar, and muscovite.
No, the Vindhyan system is primarily made up of sedimentary rocks. Igneous rocks, which are formed from the cooling of molten lava or magma, are not a dominant component of the Vindhyan system.
An igneous rock's color is mainly determined by its silica content.
The color of igneous rocks is determined by the minerals present in the rock. Dark-colored igneous rocks, such as basalt, contain minerals like pyroxene and olivine that are rich in iron and magnesium. Light-colored igneous rocks, such as granite, contain minerals like feldspar and quartz that are rich in silicon and aluminum. These mineral compositions influence the overall color of the 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.

The color of igneous rocks is determined by their mineral composition. Dark-colored igneous rocks, like basalt, contain minerals that are rich in iron and magnesium, which give them their dark appearance. Light-colored igneous rocks, like granite, tend to have higher concentrations of quartz and feldspar minerals, which are lighter in color. Overall, the mineral content and composition of the rock influence its color.
