Mare ridges and related studies: Part D: small structures of the Taurus-Littrow region Mare ridges and related studies: Part D: small structures of the Taurus-Littrow region
Apollo 17 permission geologic studies of the Taurus-Littrow region of the Moon revealed numerous small structures, in both mare and terra, having somewhat similar morphologies and variously resembling fault scarps, flow fronts, and mare ridges. Many of these features are too small to be identified on Lunar Orbiter IV photographs, which provided the most comprehensive, high-resolution...

Stratigraphic studies: Part C: relative ages of some near-side mare units based on Apollo 17 metric photographs Stratigraphic studies: Part C: relative ages of some near-side mare units based on Apollo 17 metric photographs
The lunar maria formed at different times and in multiple stages of extrusion. An understanding of their evolution is essential in placing the Apollo samples in a regional context and in interpreting the regional geology of a vast part of the lunar surface.

Remote sensing and photogrammetric studies: Part A: remote sensing of Mare Serenitatis Remote sensing and photogrammetric studies: Part A: remote sensing of Mare Serenitatis
Mare Serenitatis is a circular mare approximately 600 km in diameter in the northeast quadrant of the lunar near side. It occupies an old multi-ringed basin (refs. 33-1 and 33-2) and is the site of a prominent mascon (ref. 33-3). A conspicuous dark annulus in this mare prompted subdivision of the mare materials into different stratigraphic units (refs. 33-2 and 33-4). A revised...

Remote sensing and photogrammetric studies: Part D: repeatability of elevation measurements--Apollo photography Remote sensing and photogrammetric studies: Part D: repeatability of elevation measurements--Apollo photography
Stereoscopic photographs of the Moon taken by the metric and panoramic cameras on board the service module of Apollo spacecraft provide a source for quantitative data on lunar topography. The accuracy of the topographic data depends, in part, on the repeatability of elevation measurements. The repeatability depends on contrast in the stereoscopic image and is affected by many factors...

A preliminary report on U.S. Geological Survey geophysical studies of the northeastern United States Outer Continental Shelf A preliminary report on U.S. Geological Survey geophysical studies of the northeastern United States Outer Continental Shelf
Regional geological and geophysical studies are being conductedby the U.S. Geological Survey to determine the structural framework of the area from Cape Hatteras to the northeastern edge of Georges Bank in order to assess the petroleum potential of the Atlantic Outer Continental Shelf. Preliminary interpretations of geophysical data and integrating gravity and magnetic data from the U.S...

Preliminary geologic investigation of the landing site: Appendix A: lunar surface orientations of Apollo 17 rock samples Preliminary geologic investigation of the landing site: Appendix A: lunar surface orientations of Apollo 17 rock samples
The lunar surface orientations of some of the Apollo 17 rock samples at the time of their collection (table 6-V) are shown in this appendix (figs. 6-65 to 6-87). These orientations were determined by correlating lunar photographs of samples before collection with shapes and shadow characteristics of the same samples in the LRL under oblique illumination with nearly collimated light. The...

Remote sensing and photogrammetric studies: Appendix to Part C: effect of photogrammetric reading error on slope-frequency distributions Remote sensing and photogrammetric studies: Appendix to Part C: effect of photogrammetric reading error on slope-frequency distributions
Lunar slope-frequency distributions obtained by photogrammetric techniques are compared with results from the bistatic-radar investigations of the Apollo 14, 15, and 16 missions (refs. 33-16, 33-17, and 33-32) and of Explorer 35 (ref. 33-27). Algebraic standard deviations of slope-frequency distributions from photogrammetric data are equivalent to rms slopes of slope-frequency...
