MagIC Method Codes
Code Method Type IAGA7 URL Description
LP-PI Lab Protocol   Paleointensity experiment. Minimal paleointensity method code, further information, about the basic method, alteration checks, and reciprocity checks can be specified using additional LP-PI codes described below.
LP-PI-ALT-AFARM Lab Protocol LINK Paleointensity experiment: Alteration check using AF demagnetization of ARM. A method to detect alteration that uses AF demagnetization of an ARM, before and after heating to impart TRM. Changes in the ARM coercivity spectrum indicate alteration. Shaw 1974.
LP-PI-TRM Lab Protocol   Paleointensity experiment: Using a laboratory TRM. Any paleointensity experiment that uses a TRM produced in a lab controlled field. Includes all variants of the Thellier method, including the Shaw method. More details on alteration and reciprocity checks can be added using the special LP-PI-ALT and LP-PI-BT method codes. Thellier 1938.
