Red beds geology.
Traditional paleomagnetic field tests are not always available to constrain the origin of NRM in red beds. Even when available, they often fail to reveal remagnetization occurring before folding but long after deposition, which leads to a false-positive fold test (e.g., Li et al., 2017), and remagnetization occurring in a long geologic intervals of dual …
