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.
