  • AbstractThe modelling gravity anomaly of fault model with a model sheet approach with the aim to study the response of gravity anomalies of faults was done.Modelling is done by modelling approaches bedding with a thickness t and density contrastwith surrounding Δρ. The gravity anomaly at a point are formulated and the calculation andvisualization program created in matlab8RS. From the modelling is made it can be concluded that the fault position is generally locatedbetween the gravity anomaly minimum and maximum gravity anomaly. When thetypes of fault arevertical normal fault then the fault position precisely located on the horizontal gradient maximumvalue, whereas when the fault are not vertical, the location of fault are to be near (around) themaximum horizontal gradient.Key words: modelling, gravity anomalies, faults, model sheets.
