Igneous rocks can be either intrusive or extrusive, based on their location upon solidification from magma. Igneous rocks can also be grouped by chemistry and mineral content as felsic, intermediate, or mafic, mainly on the abundance of silicate minerals that are present.

What is the main type of energy used to help convert metamorphic rocks into igneous rocks?

The main type of energy used to help convert metamorphic rocks into igneous rocks is heat. This heat can come from processes such as magma intrusion, volcanic activity, or tectonic movements, causing the metamorphic rocks to melt and recrystallize into igneous rocks.


What are the main minerals used to make igneous rocks?

Igneous rocks are primarily composed of silicate minerals, with the main types being feldspar, quartz, mica, and pyroxene. Feldspar is the most abundant mineral group, while quartz is significant in many igneous rocks due to its resistance to weathering. Other important minerals include olivine and amphibole, which contribute to the diverse textures and compositions of igneous rocks formed from molten magma.

Could radioactive dating only be used for igneous rocks?

Radioactive dating is only useful in dating igneous and metamorphic rock. Organic material that has not fossilized and does not exceed 70,000 years of age can be dated by Carbon dating techniques. Sedimentary rock can only be dated by its association with igneous and metamorphic rock.
