During a Thellier-type paleointensity experiment, the specimen is reheated to a lower temperature and cooled in the laboratory field, thus reapplying a pTRM. Thellier & Thellier 1959 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 LP-PI-TRM-IZ Lab Protocol Paleointensity experiment: Using a laboratory TRM with an in-field step followed by a zero-field step Heating the specimen to the desired temperature step and then cooling in known ambient magnetic field. Then heating to the same or lower temperature and then cooling in zero magnetic field to induce pTRM.
