Introduction to paleomagnetic sampling points: Magnetic minerals are affected by the paleomagnetic magnetic field, causing the poles of the magnetic material to point to the two magnetic poles of the ancient earth, and are subsequently fixed in the rocks. It reflects the paleomagnetic characteristics before diagenesis and is used to compare the age of rock formation.
