paleomagnetism is valuable because it is the only dating method that
provides absolute dates for fossil deposits laid down during the crucial period between 500,000 and 50,000 years ago.
can provide a time framework that can allow geological, climatological, and evolutionary events to be related on a worldwide scale.
provides absolute dates for clay artifacts and objects made from volcanic ash.
can date organic remains that fossilized more than 100,000 years ago.
Paleomagnetism studies the Earth's magnetic field in the past. It helps create a global - scale time framework. Other dating methods like radiocarbon (for organic remains, limited to about 50,000 years) or some absolute dating methods for specific materials (e.g., potassium - argon for volcanic materials) have more limited scopes. Paleomagnetism's unique value is in its ability to relate events globally.
