Quartz and feldspars are the most common silicate minerals of the crust.
The most common minerals found in Earth's crust are quartz, feldspar, and mica. These minerals make up a significant portion of the Earth's continental crust and are essential components of many rock types.

Decaying uranium atoms in the Earth's crust are radioactive and release energy in the form of alpha, beta, and gamma radiation as they decay. This process occurs at a constant rate known as the half-life of uranium. The decay of uranium atoms plays a significant role in the geologic processes and the formation of Earth's natural resources.
Uranium is usually found in nature in the form of uranium ore, which is a combination of uranium, oxygen, and other elements. It can take the form of minerals such as uraninite, coffinite, and carnotite.
