WebbAfter World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. In the early to mid 1960s, Dr. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating. How does Magnetism work? WebbRadiometric dating is the primary dating scheme employed by scientists to determine the age of the earth. Radiometric dating techniques take advantage of the natural decay of radioisotopes. An isotope is one of two or more atoms which have the same number of protons in their nuclei, but a different number of neutrons.
