Magnetostratigraphy of the Lower Carboniferous [PDF]

open access: yes, 2020
Geomagnetic polarity reversals studied by magnetostratigraphy have been described well in the Cenozoic and Mesozoic, unfortunately, there are still many data gaps in the Palaeozoic where the magnetostratigraphic record is not easy to correlate or is unknown. One of those is during the Carboniferous System. The magnetostratigraphy of Carboniferous rocks
