Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Post-Depositional Fluid Flow in Jurassic Sandstones of the Uncompahgre Uplift: Insights From Magnetic Fabrics (2020), Frontiers in Earth Science. Implementations in other papers (listed below) may differ.

1. Thermal demagnetization
   Stepwise thermal demagnetization of Natural Remanent Magnetization (NRM) was performed at the UNM-ALP laboratory using a Superconducting Rock Magnetometer 2G Enterprise 755 hosted in a shielded room. Specimens were subjected to a stepwise thermal demagnetization in 15 steps from room temperature to 600°C, with additional four steps up to 700°C for specimens showing higher unblocking temperatures
   Quantities: Forty-eight representative AMS cubes (16 per formation) selected for thermal demagnetizationDuration: Not specifiedConditions: Room temperature to 700°C in shielded room
   Equipment: Superconducting Rock Magnetometer 2G Enterprise 755
