Abstract
The hypsometric map and the basin height profiles, for the first time relying
upon a spherical daturence surface, have been constructed based on the
generalization of the heights measured within the hemisphere including the ring
structure of the South Pole–Aitken basin. The distribution of the major chemical
elements (Fe and Th), depending upon the structure height levels, has been
obtained. The relationship between these lunar rock indicators and the height
levels of the rock preferential distribution has been revealed. The outer basin
ring has been distinguished and the ring structure of the central basin
depression has been revealed against a combined hypsometric and geochemical
background. A total basin diameter of about 3500 km has been reliably determined
for the first time. A unique feature of the basin structure consists in that the
arrangement of the basin inner rings does not show a central circular symmetry,
which can indicate that a hypothetical impactor moved along the trajectory (or
orbit) oriented almost normally to the ecliptic plane. In combination with the
revealed very small depth–diameter ratio in the initial basin structure, this
circumstance makes it possible to put forward the hypothesis that a comet impact
produced the South Pole–Aitken basin.
