Absolute ages of the lunar maria and large craters

Icarus, 1969
Abstract By an analysis of the changes in rim heights of lunar craters through isostatic settling, combined with inferences from counts of small impact craters contained within and subsequent to large craters, it is concluded that: (1) the maria are not older than about 640 million years; and (2) the flux of masses which produced craters larger than ...

Internal origin for lunar rilled craters and the maria?

Nature, 1974
THE origin of lunar craters has been attributed to both volcanism1–3 and/or impact4–6, although since the return of the Apollo 11 volcanic rocks opinion has favoured an endogenic origin for a greater part of the lunar morphology than was previously accepted7.

Nature of the Density Reversal Beneath the Lunar Maria

Geological Society of America Bulletin, 1972
The density of basalt samples from Mare Tranquillitatis and Oceanus Procellarum is 3.36 g/cm 3 . These basalts should undergo a phase change at a pressure of approximately 10 kbar (200 km lunar depth) that would increase the density to 3.74 g/cm 3 . This density is substantially higher than the average density of the moon; therefore, lunar maria must ...

The Distribution and Ages of Regional Lithologies in the Lunar Maria

1970
A research program was designed (1) to map regional lithological units of the lunar surface based on measurements of spatial variations in spectral reflectance, and, (2) to establish the sequence of the formation of such lithological units from measurements of the accumulated affects of impacting bodies.
