COMPUTATION AND APPLICATION OF THE FOURTH DERIVATIVE OF THE GRAVITATIONAL ANOMALY

In this paper, the horizontal fourth derivatives in two-dimensional space and the vertical fourth derivatives in three-dimensional space were derived with the use of the Taylor expansion. Some theoretical aspects of fourth derivatives were discussed, and the derivatives of the real gravity data in some areas were computed. The geological results are satisfactory.
