Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows
Orbital photographs taken at low-Sun illumination during both the Apollo 15 (ref. 30-14) and Apollo 17 missions have provided excellent data on the lava flows in the southwestern Mare Imbrium. These photographs have been used recently to present a detailed photogeologic evaluation of these flows and their role in mare volcanism of Eratosthenian age in the basin (ref. 30-15). Eruption of...

Preliminary geologic investigation of the Apollo 17 landing site Preliminary geologic investigation of the Apollo 17 landing site
The Apollo 17 lunar module (LM) landed on the flat floor of a deep valley that embays the mountainous highlands at the eastern rim of the Serenitatis basin. Serenitatis, the site of a pronounced mascon, is one of the major multi-ringed basins on the near side of the Moon. The Taurus-Littrow valley, which is radial to the Serenitatis basis, is interpreted as a deep graben formed by...

Surface electrical properties experiment Surface electrical properties experiment
The surface electrical properties (SEP) experiment was used to explore the subsurface material of the Apollo 17 landing site by means of electromagnetic radiation. The experiment was designed to detect electrical layering, discrete scattering bodies, and the possible presence of water. From the analysis of the data, it was expected that values of the electrical properties (dielectric...

Mare ridges and related studies: Part C: lunar thrust faults in the Taurus-Littrow region Mare ridges and related studies: Part C: lunar thrust faults in the Taurus-Littrow region
"Wrinkle ridges" in the Taurus-Littrow region along the eastern margin of the Mare Serenitatis appear very fresh and are probably among the youngest on the Moon. They include both mare ridges and similar-looking one-sided scarps. Evidence will be presented here to suggest that these ridges and scarps may be anticlines and thrust faults that resulted from sliding on a décollement surface

Stratigraphic studies: Part A: basalt stratigraphy of southern Mare Serenitatis Stratigraphic studies: Part A: basalt stratigraphy of southern Mare Serenitatis
Mare Serenitatis has long been noted for its conspicuous dark border (fig. 29-1). The Apollo 17 metric photographs traverse this border in southern Mare Serenitatis and show clearly superposition relationships among the mare and mare-related stratigraphic units. These photographs, together with full-Moon photographs, albedo measurements, and color information (table 29-I), provide the...

Structure of the crust in the conterminous United States Structure of the crust in the conterminous United States
On the basis of the newest interpretations of all sufficiently long seismic profiles, a contour map of the Mohorovičić discontinuity for the conterminous United States is compiled. Differences from earlier interpretations are discussed.

Interstitial water studies on small core samples, Deep Sea Drilling Project: Leg 10 Interstitial water studies on small core samples, Deep Sea Drilling Project: Leg 10
Leg 10 interstitial water analyses provide new indications of the distribution of rock salt beneath the floor of the Gulf of Mexico, both confirming areas previously indicated to be underlain by salt bodies and extending evidence of salt distribution to seismically featureless areas in the Sigsbee Knolls trend and Isthmian Embayment. The criterion for presence of salt at depth is a...
