How does silica affect the color of igneous rocks? | Socratic
These are rocks like basalt, which is very darkly coloured. So how pale a rock is can be a very good indication of whether it's felsic (high in silica) or mafic (low in …

Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important component of the Earth's continental crust. Basalt is formed through the rapid cooling and solidification of magma at Earth's surface, resulting in the formation of lava ...

Quartz. Quartz is one of the most common minerals in the Earth's crust. It is made of silicon dioxide (SiO2), otherwise known as silica. Varieties of quartz based on color include: amethyst (purple), smoky quartz (grey), rose quartz (pink), and citrine (yellow-green). Quartz has a glassy luster and a hardness of 7.

The another kind of classification is based on rock's composition. All igneous rocks can be devided into felsic, intermediate, mafic and ultramafic rocks. The felsic rocks (e.g. granite) contain much silicon, while ultramafic (e.g. peridotite) rocks contain least silicon. Basalt and gabbro which are mentioned above are mafic rocks.

Mineralogy. When basaltic lava is abruptly quenched, it solidifies to glass. When slowly cooled, it crystallizes, more or less completely, to an assemblage of minerals. We may speak of the mineralogy of basalts in terms of these minerals ( modal composition), and of the chemistry of basalts both in terms of elements (or oxides) and the ...
