Paleomagnetic dating, a study mostly concerned with sediments, rocks, and tectonic processes, has also been used with success in the past (blanco et al, 2013 symons and arne, 2005 symons and sangster, 1991) however, there is often a lack of communication into the exact method used in dating the geologic material via paleomagnetism.

Paleomagnetism (or palaeomagnetism in the united kingdom) is the study of the record of the earth's magnetic field in rocks, sediment, or archeological materials certain minerals in rocks lock-in a record of the direction and. The limitations of paleomagnetic and archaeomagnetic dating using this technique, a core or sample can be directly dated there are a number of limitations, however first, it is necessary to know the approximate age of the sample to avoid miscorrelations the k-ar method has been used to place the sample in an approximate age range.
