A new method for the determination of paleointensity from the A.R.M. properties of rocks

The relation between the mechanisms of thermoremanent magnetization (TRM) and anhysteretic remanent magnetization (ARM) considered by Nagata (1961) is utilized in the new method. It is shown experimentally that the ratio of room temperature TRM and ARM susceptibilities can be determined quantitatively from the intrinsic magnetic parameters of the rock. Questions of the theoretical background of the method are examined along with details regarding the experimental technique.-
