Characteristics of the Matuyama‐Brunhes Magnetic Field Reversal Based on a Global Data Compilation
Journal of Geophysical Research: Solid Earth, Volume 128, Issue 2, February 2023., 2023 Abstract Magnetic field reversals are irregular events in Earth's history when the geomagnetic field changes its polarity. Reversals are recorded by spot and continuous remanent magnetization data collected from lava flows and marine sediments, respectively.

Short-Term Magnetic Field Variations From the Post-depositional Remanence of Lake Sediments
Frontiers in Earth Science, 2018 Paleomagnetic records obtained from lake sediments provide important constraints on geomagnetic field behavior. Secular variation recorded in sediments is used in global geomagnetic field models, particularly over longer timescales when archeomagnetic ...

Magnetic characteristics and archeointensity determination on Mesoamerican Pre-Columbian Pottery from Quiahuiztlan, Veracruz, Mexico [PDF]
Geofísica Internacional, 2008 We report a detailed archeomagnetic investigation on pre-Columbian potteries from Quiahuiztlan, Veracruz, from ~900 AD to 1521 AD. Archeological samples analyzed by modern magnetic techniques carry a stable univectorial thermoremanent magnetization under
