Also successive periods can be found in any available object for observation, if we have enough data for analysis. Even Earth has such successive periods of forming but many have been erased by erosion, the atmosphere. But the Moon has no atmosphere and all stages of its formation are more easily understood by scientists.
I believe that parts of southeast and south of the Moon, are the most ancient lands because they were not affected by the seas that covered much of the surface. Also in these images crater walls were untouched by floods of Mare Humorum. Examples are Gassendi (110 km) Mersenius (84 km) Liebig (37 km), Gasparis (30 km), Cavendish (56 km), Freres (42 km), Byrgius (87 km) - in the shade.

In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.
