What is the most common type of mineral on Earth?

The most common mineral on Earth is silicate minerals, which make up over 90% of the Earth's crust. These minerals are made up of silicon and oxygen, which combine to form various types of silicate minerals, such as feldspar, quartz, mica, and olivine.

Feldspar is the most abundant mineral in the Earth's crust, making up about 60% of the crust's volume. Quartz is the second most common mineral, making up about 12% of the Earth's crust.

Non-silicate minerals, such as carbonates, sulfates, and halides, are much less common on Earth compared to silicate minerals.
