Аннотация:The harmonic and statistical analysis of lunar terrain altitudes has been performed based on the
procedure developed by the authors. The explanations for the displacements of the Moon’s figure relative to
the center of mass and for the shift of the major equatorial axis relative to the earthward direction have been
given. The maps have been plotted for the density anomalies in the near-surface layers of the Moon that correspond
to mascons (with negative correlation between the field and terrain mainly for N = 10, 11) and other
variants of links between the gravitational field and terrain (with positive correlation between the field and terrain).
It has been shown that the harmonics of the degree N = 5–9 mainly correspond to the isostatic compensation
of the terrain in the near-surface layers of the crust; the low harmonics (N < 5) correspond to the
isostatic compensation of the terrain in the deeper layers, while the harmonics of the degrees N > 11 may indicate
the presence of tension in the crust generated by small structures of the terrain. Based on the maps, possible
locations of deposits of volatile elements (mainly on the far side of the Moon and in the northern circumpolar
region) and other natural resources have been determined.
