magnetisaatioaika
Magnetisaatioaika, also known as the Paleomagnetic Chron, is a time scale used in geology and archaeology to date rocks and artifacts based on their magnetic properties. It is analogous to the geological time scale but is based on the magnetic field reversals recorded in the Earth's crust. The concept was first introduced by Motonori Matuyama in 1929, who observed that the Earth's magnetic field had reversed polarity multiple times in the past.
The magnetisaatioaika is divided into epochs, which are further subdivided into polarity chrons. Each chron represents
This time scale is particularly useful in dating volcanic rocks, sediments, and archaeological materials that contain
