How to Detect and Correct a Compaction - shallowed Inclination - Paleomagnetism of Sedimentary Rocks: Process and Interpretation - page 52

Fig. 5.6 Stereonets showing different magnetic fabrics for the Perforada Formation (Vaughn et al . 2005). As both AMS and
AAR (ARM anisotropy) decrease, the paleomagnetic inclination of the rocks becomes steeper, supporting the use of magnetic
anisotropy to detect and correct for inclination shallowing. Reprinted from Earth and Planetary Science Letters , 232, J Vaughn,

Fig. 5.7 Site mean directions before (left) and after (right) individual sample-by-sample magnetic anisotropy correction of
inclination shallowing (Kodama 1997). The mean of the site means (square with 95% confi dence circle) moves from
shallower than the expected Paleocene direction for North America, shown by gray hexagon (based on Diehl et al . 1983 ), to
nearly exactly in agreement with it after correction. KP Kodama, A successful rock magnetic technique for correcting
