That's partially correct! Granite is primarily composed of feldspar and quartz. Mica is also a common mineral found in granite, but it's not one of the two main components.

Here's a breakdown:

* Feldspar: Makes up the largest percentage of granite, giving it its light color.

* Quartz: The second most abundant mineral, contributing to granite's hardness and durability.

* Mica: Present in smaller amounts, giving granite its characteristic sparkle and sometimes a layered appearance.

So, while mica is a part of granite, the primary minerals making up the rock are feldspar and quartz.
