Preliminary geologic investigation of the Apollo 16 landing site Preliminary geologic investigation of the Apollo 16 landing site
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 that there are indeed few or no volcanic rocks...

Photogeology: Part G: structural aspects of Imbrium sculpture Photogeology: Part G: structural aspects of Imbrium sculpture
Apollo 16 metric photographs taken at low to high Sun angles (from approximately 7° to 40°) provide the first stereographic coverage of the distinctive landforms collectively referred to as "Imbrium sculpture" (refs. 29-40 and 29-41). The sculpture consists of a series of nearly linear ridges and troughs extending radially outward for more than 1000 km from the rim of the Imbrium Basin...

Orbital-science investigation: Part B: photogrammetric analysis of Apollo 15 records Orbital-science investigation: Part B: photogrammetric analysis of Apollo 15 records
The three cameras—stellar, mapping, and panoramic—together with the laser altimeter, all included in the scientific instrument module (SIM) bay, represent an integrated photogrammatric system with extraordinary potential for extending knowledge of the lunar figure, surface configuration, and geological structure.

Photogeology: Part B: Cayley Formation interpreted as basin ejecta Photogeology: Part B: Cayley Formation interpreted as basin ejecta
The discovery that samples returned from the Cayley Formation at the Apollo 16 landing site consist mainly of nonvolcanic breccias (secs. 6 and 7 of this report) suggests that the hypothesis in which light plains-forming materials may be ejecta from multi-ring basins should be reevaluated (refs 29-15 to 29-17). Improved information on the morphology and distribution of the Cayley...

Orbital-science investigation: Part F: regional geology of Hadley Rille Orbital-science investigation: Part F: regional geology of Hadley Rille
Study of the sinuous Hadley Rille (fig. 25-45) was a primary goal of the Apollo 15 mission. Local geology of the rille near the landing site is described in section 5 of this report. Preliminary study of orbital photography from Hasselblad, metric, and panoramic cameras makes possible a description of some regional relationships of the rille. Considerable use is also made of a...

Photogeology: Part A: relative ages of some near-side and far-side terra plains based on Apollo 16 metric photography Photogeology: Part A: relative ages of some near-side and far-side terra plains based on Apollo 16 metric photography
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 McCauley (ref. 29-4) simply called these materials Imbrian plains (Ip). The age relationships...

Preliminary geologic investigation of the Apollo 15 landing site Preliminary geologic investigation of the Apollo 15 landing site
The Apollo 15 lunar module (LM) landed at longitude 03°39'20'' E, latitude 26°26'00'' N on the mare surface of Palus Putredinis on the eastern edge of the Imbrium Basin. The site is between the Apennine Mountain front and Hadley Rille. The objectives of the mission, in order of decreasing priority, were description and sampling of three major geologic features—the Apennine Front, Hadley...

Two former faces of the moon Two former faces of the moon
Systematic geologic mapping of the lunar near side has resulted in the assignment of relative ages to most visible features. As a derivative of this work, geologic and artistic interpretations have been combined to produce reconstructions of the Moon's appearance at two significant points in its history. The reconstructions, although generalized, show the Moon (1) as it probably appeared...

Atmospheric collection of debris from the Revelstoke and Allende fireballs Atmospheric collection of debris from the Revelstoke and Allende fireballs
In two separate events, Revelstoke and Allende, the air through which a fireball had been observed to pass was sampled for meteoritic debris. Particulate matter was collected on fibrous filters, which were mounted on aircraft and flown downwind from the site of the meteorite fall at altitudes of 10,000–12,000 m. From Revelstoke, a highly distinctive assemblage of particles was collected...

Preliminary geologic investigation of the Apollo 12 landing site: Part B: photometric and polarimetric properties of the lunar regolith Preliminary geologic investigation of the Apollo 12 landing site: Part B: photometric and polarimetric properties of the lunar regolith
Several special, as well as general, photometric and polarimetric studies of the lunar regolith in the vicinity of the Apollo 12 landing site have been undertaken by means of the black-and-white photographs obtained on the geologic traverse during the second extravehicular activity (EVA) period.

Preliminary geologic investigation of the Apollo 12 landing site: Part A: Geology of the Apollo 12 Landing Site Preliminary geologic investigation of the Apollo 12 landing site: Part A: Geology of the Apollo 12 Landing Site
This report provides a preliminary description of the geologic setting of the lunar samples returned fromt he Apollo 12 mission. A more complete interpretation of the geology of the site will be prepared after thorough analysis of the data.

Bibliography of the lunar surface Bibliography of the lunar surface
The term "surface" in this bibliography is defined to include landforms and surface materials and the nature of, and processes responsible for, their physical characteristics. References are divided into two listings: (1) Surface features and materials; and (2) Telescopic observations. The former is accompanied by a subject index, the latter by a locality index.
