Abstract:The examples are shown of interactive interpretations of gravity data by CYBER I72 computer, The interpretation procedure is as follows;(1)high frequency noises are eliminated by smoothing the curve of observations, replacing strange points, and conducting nonlinear filtering;(2) low frequency background is eliminated by making upward continuation and trend analysis, and drawing a line through starting point and end point;(3)a eroid model is used to make forward and inverse interpretations of gravity anomaly (Dg),its first derivative (gz) and second derivative (gzx).The example of J area,where many fault blocks exist because of complicated geological struetore, proves this method to be quite useful.
