Photogeology: Part Y: physical and geological aspects of heiligenschein measurements
Robert L. Wildey
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Heiligenschein is the upsurge in reflected brightness as zero-phase angle is approached. For the first time, an effort has been made to investigate the diagnostic value of the heiligenschein photometric magnitude on a statistically significant scale. This investigation was performed by using the vertical photography of the Apollo 16 metric...

Orbital-science investigation: Part G: lineaments that are artifacts of lighting
Keith A. Howard, Bradley R. Larsen
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
Many Apollo 15 orbital photographs, particularly those taken at low Sun-elevation angles, reveal grid patterns of lineaments. In some circumstances, the grid pattern is present in areas where structural control seems unlikely. For example, in an oblique view (fig. 25-52), the ejecta blankets of two fresh impact craters seem to...
Photogeology: Part A: relative ages of some near-side and far-side terra plains based on Apollo 16 metric photography
Laurence A. Soderblom, Joseph M. Boyce
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The materials of most light or terra plains predate the lunar maria and postdate the Imbrian event. In the vicinity of the Imbrium Basin, these materials have been called the Cayley Formation (ref. 29-3) but because of the subtle diversity of the terra plains over the near side, Whilhelms and...

Wolfe, J.W. Young
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The Apollo 16 landing site in the lunar central highlands encompassed terra plains and adjacent mountainous areas of hilly and furrowed terra. These morphologic units, representing important terrane types in the lunar highlands, had been interpreted as volcanic on most premission geologic maps. However, it became apparent during the mission...

L.A. Soderblum
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
The processes by which craters disappear from the lunar surface have been of principal concern since the first high-resolution pictures of the lunar maria were returned by Ranger VII.
