Magnetic polarity map
WebSep 14, 2024 · Earth’s magnetic field is generated by the convection of molten iron in the planet’s core, around 1,800 miles (2896 km) beneath our feet. This superheated liquid generates electric currents that... WebThe magnetic reversal block model was derived for the Hawaiian lineations, but the ages were determined for sites on other lineation sets and correlated by the magnetic polarity pattern to the Hawaiian set. The LH75 polarity sequence has formed the basis for subsequent modifications and improvements to the M‐sequence GPTS (Figure G33).
