“…Prolonged and involved endogenetic alteration of a large impact crater can yield a surface morphology deceptively unlike the original impact crater shape. It is not surprising that some authorities choose to interpret the configurations of large lunar craters as surface cauldrons and large calderas rather than as deformed impact structures [Green, 1965, McCall, 1966, $hteinberg, 1965. However, large lunar craters photographed by Ranger and Orbiter spacecraft do not appear to be of totally internal genesis.…”

The 1∶1 correspondence of crater rim volume to true crater volume allegedly observed for many lunar craters has been explained previously by the theories of explosive meteoritic impact. In fact, the equality occurs too infrequently to be of genetic significance. The ratio characteristically is about 0.4 to 0.8 for small, freshly formed lunar and terrestrial craters, but it is well over 1.0 in older and larger lunar craters. Most of the moon's craters are of explosive impact origin and acquire a specific, predictable shape governed by the law of allometric growth. Fresh crater dimensions and volumes are related by expressions of the form y = axb. Up to a diameter of 10 to 20 km, craters are stable landforms. Larger craters deform isostatically and are further modified by extrusive activity. Application of an allometric fresh crater shape model to Tycho suggests that even the most youthful appearing large lunar craters do not long retain their initial rim and true crater volumes, but that they begin to deform soon after impact.

Thermoluminescence is investigated as a possible cause of transient lunar events. Energy derived from earthshine, or from solar particle and electromagnetic radiation, could be stored in surface traps and released after sunrise to yield observable thermal glow. Glow curves are computed using the actual lunar heating rates applied to materials whose parameters describe the range of all solids. The glow intensities of some possible materials are found to exceed the scattered solar background up to several days after sunrise. Of ninety‐seven recent events, one‐third occurred in the first 24 hours after dawn. However, two observational effects increase the apparent frequency of dawn events so that the data neither support nor contradict the hypothesis of thermal glow. Other possible mechanisms for lunar glow, i.e. internal effects, photon‐stimulated luminescence, and cryoluminescence, are briefly discussed. It is shown that the Aristarchus events were probably caused by internal effects.

“…One of the more interesting stimuli for Precambrian lunar protolife is fumarolic spatter and wet/dry cycles, combined with lower lunar gravity and surface pressure (Green, 1965). Spatter of particles 0.1 m or less from fumaroles on earth at Kuirau Park in Rotorua in New Zealand on January 26, 2001 were thrown 100 m. On the moon, this would produce a spatter blanket of some one million square meters.…”
