This dating is used on clay remains and as the magnetic north pole has been several times in the same geographical coordinates, you get more than one date. Depending on the context of the site, you may discard some dates to reach a final dating. Certain minerals quartz, feldspar, calcite … accumulate in its crystal structure changes due to radioactive decay of the environment.

Relative Dating

The majority of the time fossils are dated using relative dating techniques. Using relative dating the fossil is compared to something for which an age is already. Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil?.

These changes are cumulative, continuous and time dependent to radiation exposure. When subjected to external stimuli, mineral emits light due to these changes.
