Ferropericlase is a mineral phase with the chemical formula (Mg,Fe)O. It is a solid solution of periclase (MgO) and ferropericlase ((Mg,Fe)O). The iron content in ferropericlase can vary significantly, typically ranging from 10% to 50% of the total cation content. This mineral is found predominantly in the Earth's lower mantle, where it constitutes a significant portion of the mantle's mass. Its formation is a result of high pressure and temperature conditions.

Ferropericlase plays a crucial role in geophysics and geochemistry due to its abundance and properties. Its density and elastic properties are sensitive to temperature and pressure, making it a valuable indicator for seismological studies used to infer the structure and composition of the lower mantle. Researchers study ferropericlase under laboratory conditions that simulate deep Earth environments to understand its behavior. Variations in iron content affect its physical properties, such as its bulk modulus and density, which in turn influence seismic wave propagation. The presence of iron also affects its melting point and its ability to incorporate other elements. Studying ferropericlase helps scientists understand mantle dynamics, heat flow, and the overall evolution of the Earth's interior.
