title: Anomalous Features in the Behavior of the Geomagnetic Field at the End of the Cretaceous Normal Superchron: Insights from the Study of the Turonian–Santonian in the Southwestern Crimea
abstract: Abstract—In 394 samples characterizing 266 stratigraphic levels in four Turonian–Santonian sections of the Southwestern Crimea, characteristic remanent magnetization components (ChRM) acquired at the stage of diagenesis are identified. The obtained data fix the record of the paleosecular geomagnetic variation of high amplitude (root mean square deviation S = 25.9° with a fixed cut-off angle of 45°, which is about twice as high as the model S for this latitude) in the sediments formed during ~5–6
