A Simple Diagram For Gravity Interpretation By Gradients For A Lateral Varying Formation

Abstract

A simple diagram is constructed for the interpretation of the gravity anomaly arising from a formation of linear density variation. The diagram can be easily used if the horizontal gradient is also known. With the help of a modern gravimeter the gradient can be accurately measured. The diagram enables the position of the origin, the depth, the width and the" density variation of the postulated structure to be derived without the use of any computing facilities. The procedure is demonstrated by a worked example using theoretical data.
