1. This is called " detrital remanent magnetization ". 2. In the later 1AESS, the reeds themselves were of remanent magnetic material. 3. As mentioned above, magnetofossils hold a remanent magnetization when they are formed. 4. This phenomenon is called hysteresis and the remaining magnetic field is called remanent magnetism. 5. The natural remanent magnetization of an igneous rock can be altered by this process. 6. Minerals that are Ferromagnetic minerals such as magnetite also can carry a remanent magnetization or remanence. 7. The aplite is the lowest melting remanent of the granite magma, that is poor in volatiles. 8. The natural remanent magnetization is the permanent magnetism remaining in a rock or sediment after it has formed. 9. This remanent magnetization, or " remanence ", can be acquired in more than one way. 10. The sediments also acquire depositional remanent magnetization which allows them to be correlated with earth's geomagnetic reversals.
