dc.description.abstractThe near-side lunar surface has been contoured for the densities of all craters of diameter greater than 2 km. The lowest densities are concentrated toward the centers of the maria in the circular basins, and succeeding contours continue to show the circular symmetry of the basins themselves. The highland areas of the Southern Hemisphere are heterogeneous in crater density. An inverse correlation between the locations of positive density anomalies (mascons) and crater density appeared particularly for the major "mascons ". It was also apparent for the lesser anomalies.
