Solid-state reactions are chemical processes that occur between solid materials, leading to the formation of new phases or compounds without any change in the solid state. These reactions play a critical role in mineral formation, often occurring under conditions of high temperature and pressure, allowing minerals to develop through atomic rearrangement rather than melting. This concept is essential for understanding how minerals evolve and interact within the Earth's crust.
congrats on reading the definition of solid-state reactions. now let's actually learn it.
