The primary objective of a gravity survey over a sedimentary basin is to delineate the shape of the basin. To fulfill this objective, information is needed about the densities within the sedimentary section. Densities of sedimentary rocks increase with depth (mainly due to compaction), approaching that of the basement in deep
basins. Sedimentary basins are generally associated with low gravity values due to lower density of the sedimentary infill. Further, gravity modeling of a basin requires the use of expressions with hyperbolic density contrast concerning the anomaly produced by the model. The variation of the density of sediments with depth
can be represented by a hyperbolic function. In this study, a thirdorder polynomial filte... view more»
