The seven basins, Orientale, Imbrium, Crisium, Nectaris, Humorum, Serenitatis and an unnamed basin between Werner and the Altai ring show rims whose absolute and relative heights are correlated with the sharpness and crispness of the features. On the assumpton that the decline in average outer rim height, not scarp height, measures the age of the basin and also that the decline represents a hot creep of rocks of very high viscosity, absolute ages were derived. Basins were found to increase in age in the sequence listed above, with a range from about 3.82 to 4.30×109years. The average or effective viscosity of the surface layers down to whatever level was involved in the creep was calculated as increasing from 9.46×1024poises at about 4.30×109years to 1.86×1030poises at present.
