As lead isotope decay at a standard and slow rate, it's able to provide fairly accurate date ranges which it measures in the millions of years.

For further details, see uranium-lead dating section below.

When these materials are heated to high temperatures through such processes as pottery firing, that is released.

Once it cools, these materials begin to absorb energy from the sun once more.

For example, astronomy uses some relative dating methods to calculate the age of the surface of planets by methods other than its materials, especially where physical samples are impossible to acquire.

Sometimes, we see them used in forensic science such as criminal investigations to determine the time and date a crime was committed, commonly when dating the time of death of a homicide victim.

There are two ways a magnetic signature forms - firstly through extreme heat such as in pottery production or hearth fires.

The second is water deposition which essentially “freezes” that magnetic particle in places (5).

The method is not as limited as we might think; it's been a vital method for some 70 years in discovering dates for ancient archaeological/anthropological deposits. Dendrochronology/Herbchronology: Dendrochronology is the study of tree ring growth and comparing a sequence to an accumulated database to come up with precise dates for events.

Most are multidisciplinary, but some are limited, due to their nature, to a single discipline.

No system is completely failsafe and no method completely correct, but with the right application, they can and have aided researchers piece together the past and solve some of their discipline's most complex problems.
