The record of the intensity of Earth"s magnetic field during the past (paleointensity) carries important information about the geodynamo and probably about the state of Earth"s interior. Firm conclusions regarding long-term paleointensity variation and its role in mantle dynamics require more data than are currently available. There are three important geophysical issues concerning about the Mesozoic paleointensity which are currently debated: (1) if there was an extended period of low field intensity in the Mesozoic, “Mesozoic Dipole Low”; (2) the need to test the recent suggestion that the field strength was unusually high during the Cretaceous Normal Superchron; and (3) if there was a correlation between reversal rate and geomagnetic field strength. In this study we reviewed the recent research results on the above issues and discussed the opportunity of paleointensity study on the Korean volcanic rocks for contributing to solve the above geophysical problems.
