“…The AMS method is a petrofabric tool to determine preferred orientation of particles under an external force, such as gravity, wind, magnetic field, water flow, and strain, during deposition and diagenesis of rocks (e.g., Dallanave & Kirscher, 2020; S. Li et al., 2020; Parés et al., 1999). AMS is demonstrated to be efficient in investigating subtle tectonics‐related fabrics in weakly deformed or undeformed clay‐rich sedimentary sequences undergoing incipient tectonic deformation (Gilder et al., 2001; He et al., 2021; B. Li et al., 2020; Li et al., 2021; Lu et al., 2014; Nie et al., 2020; Parés, 2015; Parés et al., 1999; Soto et al., 2009; Su et al., 2016; Weil & Yonkee, 2012; Wu et al., 2019; Yu, Huang, et al., 2014). The comparison between AMS and paleostress data validates the reliability of AMS ellipsoids as paleostress indicator in compressional settings (e.g., Soto et al., 2009).…”
