摘要：

Measurement of crater circularity for 487 craters has shown that there are at least two populations of craters, the circularity of which appears to decrease with increasing age. Central peak formation is not confined to either population, but the subcircular population appears to be located preferentially around the circular maria. We conclude that subcircular craters are genetically related to the fracture system and stress history associated with mare formation. © 1969.
