GRAVITY PROSPECTING IN PLATFORM AREAS

Sažetak

The problem of ambiguity in the interpretation of gravity in platform areas is analised. A theoretical example is given, presenting ambiguity in the determination of depth and position of faults, even when the form of structures is known. It has been concluded, that the best method of gravity interpretation is the construction of the map and profiles showing the depths of horizon where there is the strongest density contrast. An example is given from the Sultana area in Jordan, where the gravity map is converted into the maps of »quantitative regional« and »true residual«, by means of drilling data. Interpretation of the residual by the method of gravity modelling resulted in the construction of the map of structures and depths of the density contrast horizon, with the positions and throws of the main faults.
