Classifying Igneous Rocks

Igneous rocks are classified according to their origin, texture, and mineral composition.

Mineral Composition

Mineral Mixture

Granite is a mixture of light-colored minerals, such as feldspar and quartz, and dark-colored minerals, including hornblende and different types of mica. But granite can vary in mineral composition. This affects its color and texture.

Study the circle graph and then answer the questions.

Reading Graphs:

About what percentage of granite is made up of dark minerals?

- Igneous Rocks

Rocks

Mineral Mixture

100% - (35% + 10%) = 55%

Calculating:

If the amount of quartz increases to 35 percent and the amount of dark-colored minerals stays the same, what percentage of the granite will be made up of feldspar?

- Igneous Rocks

Rocks

Mineral Mixture

The overall color would be darker.

Predicting:

How would the color of the granite change if it contained less feldspar and more mica and hornblende?
