[1] Topographical features of the lunar maria and basins / Z. F. Rodionova, E. A. Grishakina, A. Y. Zharkova, V. V. Shevchenko // Abstracts of The Tenth Moscow Solar System Symposium (10M-S3). — Vol. 1. — Space Research Institute, Moscow, 2019. — P. 136–138. Several previously unrecognized pre-Nectarian impact basins and other pre-viously suspected basins have been verified by Clementine laser altimeter data. The GRAIL inventory of lunar basins improves upon earlier lists that differed in their totals by more than a factor of 2. The size-frequency distri-butions of basins on the near side and far side hemispheres of the Moon differ substantially. The book “The Moon’s Largest craters and basins”, which incorporates information collected by the Kaguya, Lunar Reconnais-sance Orbiter and GRAIL missions, also contains the Catalog of 72 impact features more than 200 km in diameters. The sequence numbers have been established as embodiment of several lines of evidence of relative ages of the 72 lunar impact features in this Catalog. The numbers of features from 1 to 44 refer to Pre-Nectarian period, from 45 to 64 — to Nectarian period, from 66 to 69 — to Early Imbrian period, and, finally, numbers from 70 to 72 correspond to Late Imbrian period. The study of such parameters of large basins and maria profiles as absolute elevations of their bottoms and rims heights was performed in our abstract. Correlation of the Byrne’s sequence numbers with the measured parameters was fulfilled.
