Here's a quick breakdown of their relative abundance:

* Feldspar: Makes up about 60% of the Earth's crust, making it the most common mineral.

* Quartz: The second most common mineral, making up around 12% of the Earth's crust.

* Mica: A group of minerals that are relatively common but not as abundant as feldspar or quartz.

* Calcite: A common mineral, particularly in sedimentary rocks, but less abundant than feldspar or quartz.
