Geologically Meaningful <sup>40</sup>Ar/<sup>39</sup>Ar Ages of Altered Biotite from a Polyphase Deformed Shear Zone Obtained by <i>in Vacuo</i> Step-Heating Method: A Case Study of the Waziyü Detachment Fault, Northeast China
Discordant biotite <sup>40</sup>Ar/<sup>39</sup>Ar age spectra are commonly reported in the literature. These can be caused by a number of processes related to in vacuo heating, homogenization of the argon distribution, and production of misleadingly flat age spectra. Problem...
