This paper deals with the advantages of the tilt derivative method in locating boundaries of magnetic and gravity sources and presents a new theory for explaining the inclination of the geological body, which is called non-absolute horizontal derivative of tilt derivative. Some models have been designed to prove the method, and the problems existent in the tilt derivative method are pointed out. The method was employed to explain the gravity potential data of a certain area, with good results obtained.
