Paleomagnetism is the study of extracting information about past geomagnetic fields from rocks, and it has contributed to many areas of the Earth sciences, including core dynamics, chronology, and tectonics. On the other hand, rock magnetism has contributed to the development of fields such as environmental science, sedimentology, and physics of physical properties, as well as providing support for paleomagnetic data by studying the types of magnetism that remain in rocks.
Archaeomagnetism is the application of these methods to archaeological artifacts and structures. Much research has been done on the former since the 1950s, and in the 1970s the state of geomagnetic secular variation in Japan over the past 2000 years was clarified. Since then, it has been used in archaeology and cultural heritage as a dating method that compares detailed geomagnetic secular variations with highly accurate remanent magnetization directions. Recently, rock magnetism has also been applied to archaeological artifacts and remains, archeo-rock magnetism, and is used as a method for reconstructing the firing environment of pottery and estimating temperatures.
In this talk we will review the methods and contributions of archaeomagnetism and archeo-rock magnetism, and discuss how they will contribute to the development of geosciences and archaeology in the future.
