摘要
In geology and mineral resources survey and geophysical exploration, high-precision magnetic measurement is characterized by economic, practical, and fast, so it find a wide application in searching for ferromagnetic minerals and geological structures. Through comparison between practical examples, the authors point out the problem exists in current norms of normal magnetic field gradient measurements to correct the problems, discuss the correction of the normal field gradient method, and propose a new method for the correction.
