Thermal remanent magnetization (TRM) is the magnetization acquired by ferromagnetic minerals in rocks when they cool through their Curie temperature, locking in the Earth's magnetic field direction at that time. This process is crucial in understanding paleomagnetism, as it allows geologists to interpret the historical changes in Earth’s magnetic field and plate tectonics based on the orientation of these minerals in ancient rocks.
congrats on reading the definition of thermal remanent magnetization. now let's actually learn it.
