Abstract

WE HAVE DEVELOPED A METHOD TO ESTIMATE THE GEOMETRY, LOCATION AND DENSITIES OF ANOMALIES COMING FROM GRAVITY DATA. THE METHOD IS BASED ON COMPACT GRAVITY INVERSION TECHNIQUE.COMPACT GRAVITY INVERSION IS SIMPLE, FAST AND USER FRIENDLY BUT SEVERELY DEPEND ON THE NUMBER OF MODEL PARAMETER, I.E. BY INCREASING THE MODEL PARAMETER, AND THE ANOMALIES TEND TO CONCENTRATE NEAR THE SURFACE. TO OVERCOME THIS AMBIGUITY THE NEW WEIGHTING FUNCTIONS HAVE INTRODUCED HERE WHICH THEIR ELEMENTS ARE THE DENSITY, DEPTH, AND KERNEL FUNCTION OF THE MODEL TO PRODUCE COMPACTNESS, DEPTH AND KERNEL WEIGHTING MATRICES RESPECTIVELY. TEST WITH A 3D MODEL OBTAINED FROM GRAV3D SOFTWARE 2005 SHOW THAT THE METHOD CAN BE PERFORMED SUCCESSFULLY IN DEEP GRAVITY SOURCES AND THE ANOMALIES LAID CLOSE TOGETHER.
