Archaeomagnetic Dating Also Known As Paleomagnetic dating A MATLAB software tool has been developed to provide an easy to use graphical interface for the plotting and interpretation of paleomagnetic data. Definition Archaeomagnetic dating is a method of assning a date to a fireplace or burned earth area using the earth's magnetic field.
Evidence for a variable paleomagnetic lock‐in depth in the. The tool takes either paleomagnetic directions or paleopoles and compares them to a user defined apparent polar wander path or secular variation curve to determine the age of a paleomagnetic sample. Paleomagnetic data allow the determination of a well-defined characteristic. the potential of hh-resolution paleomagnetic studies in dating.
