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 F: reinterpretations of the northern Nectaris Basin Photogeology: Part F: reinterpretations of the northern Nectaris Basin
Geologic units of the Nectaris Basin rim have been interpreted as partly impact and partly volcanic in origin (refs. 29-4, 29-21, 29-35, 29-38, and 29-39). An exclusively volcanic origin was proposed for the material in the vicinity of the Apollo 16 landing site, slightly northwest of the Nectaris Basin (ref. 29-36). In view of the dominance of breccia and the paucity of volcanic...

Photogeology: Part L: crater morphometry Photogeology: Part L: crater morphometry
Morphometric analysis of lunar craters (ref. 29-75) complements the more traditional photointerpretive study of crater morphology. These two indirect approaches to the scientific investigation of lunar craters continue to be productive because the preferred alternative method, direct field examination of specific large craters, is not being undertaken in the current series of manned...

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...

Orbital-science investigation: Part K: geologic sketch map of the candidate Proclus Apollo landing site Orbital-science investigation: Part K: geologic sketch map of the candidate Proclus Apollo landing site
A panoramic camera frame (fig. 25-69) was used as the base for a geologic sketch map (fig. 25-70) of an area near Proclus Crater. The map was prepared to investigate the usefulness of the Apollo 15 panoramic camera photography in large-scale geologic mapping and to assess the geologic value of this area as a potential Apollo landing site. The area is being considered as a landing site...

Orbital-science investigation: Part L: selected volcanic features Orbital-science investigation: Part L: selected volcanic features
Preliminary examination of Apollo 15 orbital photographs indicates a large number of volcanic features. One area of exceptionally interesting volcanic activity is depicted in figure 25-74. Located approximately at latitude 25° S and longitude 123° E on the lunar far side, this region also is covered by panoramic camera photographs AS15-9954, 9956, 9958, and 9960 and by stereoscopically...

Earthquakes in the oil field at Rangely, Colorado Earthquakes in the oil field at Rangely, Colorado
Seven years of seismic data recorded at the Uinta Basin Observatory were searched for earthquakes originating near an oil field at Rangely, Colorado, located 65 km ESE of the observatory. Changes in the number of earthquakes recorded per year appear to correlate with changes in the quantity of fluid injected per year. Between November 1962 and January 1970, 976 earthquakes were detected...

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 8 Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 8
Leg 8 sites are dominated by siliceous-calcareous biogenic oozes having depositional rates of 0.1 to 1.5 cm/1000 years. Conservative constituents of pore fluids showed, as have cores from other pelagic areas of the Pacific, insignificant or marginally significant changes with depth and location. However, in Sites 70 and 71, calcium, magnesium and strontium showed major shifts in...

Man-made earthquakes and earthquake prediction Man-made earthquakes and earthquake prediction
Convincing evidence that man can trigger earthquakes has been developed since the 1963–1967 report. The fact that man can start earthquakes has increased our understanding of earthquake mechanisms and reinforced our judgment that we are approaching the possibility of earthquake prediction. Traditionally, seismologists have avoided the subject of earthquake prediction because of its...

Data file, Continental Margin Program, Atlantic Coast of the United States: vol. 2 sample collection and analytical data Data file, Continental Margin Program, Atlantic Coast of the United States: vol. 2 sample collection and analytical data
The purpose of the data file presented below is twofold: the first purpose is to make available in printed form the basic data relating to the samples collected as part of the joint U.S. Geological Survey - Woods Hole Oceanographic Institution program of study of the Atlantic continental margin of the United States; the second purpose is to maintain these data in a form that is easily...

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 6 Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 6
Sediments from Leg 6 sites, west of the Hawaiian Islands, consisted primarily of various combinations of deep-sea biogenic oozes, volcanic ash, and its breakdown products. Pore fluids from most of the sites were similar in composition to present day ocean water, and in some sties almost identical. However, interstitial fluids from Site 53 (Philippine Sea) showed changes in ionic...
