Identify what igneous rock is primarily dependent on for its chemical composition

Igneous rocks are defined as formations made from solidified lava or magma.

When lava or hot Magma reaches the surface of the earth or a water body it quickly cools down and changes it's from from a hot liquid to a solid rock.

The chemical composition of Igenous rocks can vary depending on their location, cooling time etc.

However, most Igenous rocks contain some or all of the following minerals:

1. Quartz

2. Micas

3. Amphiboles

4. Olivines

5. Pyroxenes

6. Feldspathoids

7. Feldspars
