These terra regions have much higher albedos than the physiographically lower and much smoother mare regions. The difference in albedo can now be ascribed to a fundamental difference in the chemical and mineralogical character of these two regions. Lunar samples from landing sites in the mare regions and high-resolution photographs taken from lunar orbit have shown that the lunar maria are underlain by extensive lava flows. Isotopic dating of samples from four mare regions (refs. 7-1 to 7-4) indicate that mare volcanism covered a time span of 600 million years, beginning approximately 3.7 billion years ago. The intensely cratered character of terra regions is due to both the greater antiquity of these parts of the Moon and the higher flux of incoming objects that hit the Moon during very early lunar history (ref. 7-5). In contrast with the mare region, the origin of the underlying material of the terra is not easily inferred from physiographic criteria. The surface manifestations of early plutonic or extrusive igneous activity — if indeed they ever existed — were erased from the terra regions by the intense early bombardment of the lunar surface. Some portions of the highlands may be exceptions to this generalization; in particular, large craters such as Ptolemaeus, Hipparchus, Albategnius, and Alphonsus. The regions bounded by these craters are much smoother than the typical densely cratered highlands. These regions are generally assumed to be physiographic lows that have, in some way, been filled by younger material. The nature of the material and the mechanism by which it was introduced into the basins are not well understood. On the basis of rather detailed studies of the physiographic and albedo characteristics of the basin material, it has been suggested (ref. 7-6) that the filling of the highland basins was a result of volcanic processes similar to those which filled the large mare basins. Some highland basins also contain hilly, hummocky regions that bear no relation to large crater rims or crater ejecta. These regions have been interpreted as extrusive igneous features formed by viscous, silicic, igneous liquids (ref. 7-6).","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Apollo 16 preliminary science report (NASA SP 315)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Aeronautics and Space Adminstration","publisherLocation":"Washington, D.C.","usgsCitation":"The Lunar Sample Preliminary Examination Team, 1972, Preliminary examination of lunar samples: Part A: a petrographic and chemical description of samples from the lunar highlands, chap. of Apollo 16 preliminary science report (NASA SP 315), p. 7-1-7-24.","productDescription":"24 p.","startPage":"7-1","endPage":"7-24","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":266576,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266575,"type":{"id":11,"text":"Document"},"url":"https://www.hq.nasa.gov/alsj/a16/as16psr.pdf"}],"otherGeospatial":"Moon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51065a86e4b0f227c1e454cb","contributors":{"authors":[{"text":"The Lunar Sample Preliminary Examination Team","contributorId":128123,"corporation":true,"usgs":false,"organization":"The Lunar Sample Preliminary Examination Team","id":535402,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70043129,"text":"70043129 -

The material provides raw data of a quality far superior to and more uniform than comparable data available from Lunar Orbiter or Earth-based sources.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Apollo 16 preliminary science report (NASA SP 315)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Aeronautics and Space Administration","publisherLocation":"Washington, D.C.","usgsCitation":"Pike, R.J., 1972, Photogeology: Part L: crater morphometry, chap. of Apollo 16 preliminary science report (NASA SP 315), p. 29-56-29-61.","productDescription":"6 p.","startPage":"29-56","endPage":"29-61","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":266608,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266607,"type":{"id":11,"text":"Document"},"url":"https://www.hq.nasa.gov/alsj/a16/as16psr.pdf"}],"otherGeospatial":"Moon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5107ac18e4b0df796f216e86","contributors":{"authors":[{"text":"Pike, Richard J. rpike@usgs.gov","contributorId":5753,"corporation":false,"usgs":true,"family":"Pike","given":"Richard","email":"rpike@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":472511,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70043099,"text":"70043099 - 1972 - Principal facts for gravity stations in Sulphur Springs Valley, Arizona","interactions":[{"subject":{"id":15383,"text":"ofr66100 - 1966 - Principal facts for gravity stations in Sulphur Springs Valley, Arizona","indexId":"ofr66100","publicationYear":"1966","noYear":false,"title":"Principal facts for gravity stations in Sulphur Springs Valley, Arizona"},"predicate":"SUPERSEDED_BY","object":{"id":70043099,"text":"70043099 - 1972 - Principal facts for gravity stations in Sulphur Springs Valley, Arizona","indexId":"70043099","publicationYear":"1972","noYear":false,"title":"Principal facts for gravity stations in Sulphur Springs Valley, Arizona"},"id":1}],"lastModifiedDate":"2013-02-05T10:50:27","indexId":"70043099","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1972","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"seriesTitle":{"id":360,"text":"Final Report","active":false,"publicationSubtype":{"id":6}},"title":"Principal facts for gravity stations in Sulphur Springs Valley, Arizona","docAbstract":"Observed gravity values, station locations, terrain corrections, and Bouguer gravity data are provided in tabular form for approximately 410 gravity observations in Sulphur Springs Valley, Arizona.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/70043099","usgsCitation":"Peterson, D.L., 1972, Principal facts for gravity stations in Sulphur Springs Valley, Arizona: Final Report, 12 p., https://doi.org/10.3133/70043099.","productDescription":"12 p.","numberOfPages":"14","costCenters":[{"id":671,"text":"Western Region Geology and Geophysics Science Center","active":false,"usgs":true}],"links":[{"id":266982,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"Sulphur Springs Valley","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.82,31.33 ], [ -114.82,37.0 ], [ -109.0,37.0 ], [ -109.0,31.33 ], [ -114.82,31.33 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51123841e4b0ebe69d7eb716","contributors":{"authors":[{"text":"Peterson, Donald L.","contributorId":28597,"corporation":false,"usgs":true,"family":"Peterson","given":"Donald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":472951,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70042889,"text":"70042889 - 1972 - Photogeology: Part J: ranger and other impact craters photographed by Apollo 16","interactions":[],"lastModifiedDate":"2013-01-28T12:21:21","indexId":"70042889","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1972","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"seriesNumber":"315","title":"Photogeology: Part J: ranger and other impact craters photographed by Apollo 16","docAbstract":"The Apollo 16 crew photographed an unusual variety of impact craters, including the two craters produced by the impacts of Ranger 7 and 9 spacecraft, small craters produced by boulders as they bounced downslope, craters with marked bilateral symmetry, and primary craters with a wide range of morphologies and sizes.

Of these, the majority was of value in heiligenschein studies (refs. 25-36 to 25-38). A few were of value for limited-interval delineation of the photometric functions of crater walls, wherein it is now known from past Apollo Program studies that younger craters have walls much more Lambertian in reflective properties than those of the standard lunar surface (ref. 25-39). It has now become apparent that some difficulty exists in such crater-wall studies with regard to varying the domain of mathematical definition over which such photometric functions are delineated to encompass much more of phase-angle-brightness-longitude space than has already been carried out Nearer to zero-phase angle, the brightness of the illuminated wall becomes so intense compared with the general luminance of the surrounding lunar terrain that it approaches the saturated region of the D/log E curve of the photograph where D is density and E is exposure. Conversely, for phase angles approaching 180°, most of the illuminated wall is seen so obliquely that the image size is small and reliable photometry is difficult. Also, difficulties inherent in the methodology exist—the descriptive geometry used to extract configurations begins to fail as craters become either too old or are imaged too near a vertical view Nevertheless, some useful candidates for crater-wall studies have been found in the Apollo 15 data, although their analysis is too lengthy for incorporation in this preliminary report.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Apollo 15 preliminary science report (NASA SP-289)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Aeronautics and Space Administration","publisherLocation":"Washington, D.C.","usgsCitation":"Wildey, R.L., 1972, Orbital-science investigation: Part O: regional variations in the magnitude of heiligenschein and causal connections, chap. of Apollo 15 preliminary science report (NASA SP-289), p. 25-86-25-86.","productDescription":"1 p.","startPage":"25-86","endPage":"25-86","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":265607,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":265606,"type":{"id":11,"text":"Document"},"url":"https://www.hq.nasa.gov/alsj/a15/as15psr.pdf"}],"otherGeospatial":"Moon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50f29536e4b0c9e41dd3ab9a","contributors":{"authors":[{"text":"Wildey, Robert L.","contributorId":41717,"corporation":false,"usgs":true,"family":"Wildey","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":471896,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70043043,"text":"70043043 - 1972 - Principal facts for gravity stations in the San Francisco district and adjoining areas, Utah","interactions":[{"subject":{"id":15389,"text":"ofr6699 - 1966 - Principal facts for gravity stations in the San Francisco Mountains vicinity, Beaver and Millard Counties, Utah","indexId":"ofr6699","publicationYear":"1966","noYear":false,"title":"Principal facts for gravity stations in the San Francisco Mountains vicinity, Beaver and Millard Counties, Utah"},"predicate":"SUPERSEDED_BY","object":{"id":70043043,"text":"70043043 - 1972 - Principal facts for gravity stations in the San Francisco district and adjoining areas, Utah","indexId":"70043043","publicationYear":"1972","noYear":false,"title":"Principal facts for gravity stations in the San Francisco district and adjoining areas, Utah"},"id":1}],"lastModifiedDate":"2023-06-07T18:27:23.483095","indexId":"70043043","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1972","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"title":"Principal facts for gravity stations in the San Francisco district and adjoining areas, Utah","docAbstract":"Observed gravity values, station locations, terrain corrections, and Bouguer gravity data are provided in tabular form for approximately 450 gravity observations in southwestern Utah.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/70043043","usgsCitation":"Peterson, D.L., 1972, Principal facts for gravity stations in the San Francisco district and adjoining areas, Utah, 14 p., https://doi.org/10.3133/70043043.","productDescription":"14 p.","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":266870,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Utah","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.0,37.0 ], [ -114.0,42.0 ], [ -109.0,42.0 ], [ -109.0,37.0 ], [ -114.0,37.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"510ba094e4b0947afa3c85eb","contributors":{"authors":[{"text":"Peterson, Donald L.","contributorId":28597,"corporation":false,"usgs":true,"family":"Peterson","given":"Donald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":472829,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70042876,"text":"70042876 - 1972 - Photogeology: Part F: reinterpretations of the northern Nectaris Basin","interactions":[],"lastModifiedDate":"2013-01-28T11:58:56","indexId":"70042876","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1972","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"seriesNumber":"315","title":"Photogeology: Part F: reinterpretations of the northern Nectaris Basin","docAbstract":"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 material in the returned Apollo 16 samples, it now seems appropriate to reevaluate this part of the Moon to test whether the geology of the units mapped to date can be reconciled with an impact origin. Therefore, photogeologic analysis was attempted on a strip of Apollo 16 metric photographs; the superior quality and stereographic properties of the photography permit this reevaluation (fig. 29-32). Geologic contacts, as redrawn, closely resemble those of the earlier maps cited, but some differences result because of improved photographic quality and a conscious attempt to test fully the impact hypothesis.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Apollo 16 preliminary science report (NASA SP 315)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Aeronautics and Space Administration","publisherLocation":"Washington, D.C.","usgsCitation":"Wilhelms, D.E., 1972, Photogeology: Part F: reinterpretations of the northern Nectaris Basin, chap. of Apollo 16 preliminary science report (NASA SP 315), p. 29-27-29-30.","productDescription":"4 p.","startPage":"29-27","endPage":"29-30","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":266602,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266601,"type":{"id":11,"text":"Document"},"url":"https://www.hq.nasa.gov/alsj/a16/as16psr.pdf"}],"otherGeospatial":"Moon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5107ac16e4b0df796f216e7a","contributors":{"authors":[{"text":"Wilhelms, Don E.","contributorId":28972,"corporation":false,"usgs":true,"family":"Wilhelms","given":"Don","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":472489,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70044045,"text":"70044045 - 1972 - Ground-water conditions in the central Virgin River basin, Utah","interactions":[{"subject":{"id":55974,"text":"ofr7055 - 1970 - Ground-water conditions in the central Virgin River basin, Utah - A progress report for 1968-69","indexId":"ofr7055","publicationYear":"1970","noYear":false,"title":"Ground-water conditions in the central Virgin River basin, Utah - A progress report for 1968-69"},"predicate":"SUPERSEDED_BY","object":{"id":70044045,"text":"70044045 - 1972 - Ground-water conditions in the central Virgin River basin, Utah","indexId":"70044045","publicationYear":"1972","noYear":false,"title":"Ground-water conditions in the central Virgin River basin, Utah"},"id":1}],"lastModifiedDate":"2016-12-09T16:58:00","indexId":"70044045","displayToPublicDate":"2013-01-01T00:00:00","publicationYear":"1972","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":4,"text":"Other Government Series"},"seriesTitle":{"id":294,"text":"Technical Publication","active":false,"publicationSubtype":{"id":4}},"seriesNumber":"40","title":"Ground-water conditions in the central Virgin River basin, Utah","docAbstract":"

Water-rights problems have occurred in the central Virgin River basin and are expected to increase as development of the water resources increases. The Utah State Engineer needs a basic knowledge of ground-water conditions and of the relation of ground water to surface water as a first step to understanding and resolving the problems. Accordingly, the State Engineer requested the U. S. Geological Survey to make a ground-water investigation of the central Virgin River basin as part of the Statewide cooperative agreement with the Utah Department of Natural Resources. The investigation was begun July 1, 1968, and fieldwork was completed in August 1970. Detailed information was obtained for the principal aquifers and for recharge, movement, discharge, storage, utilization, and chemical quality of ground water. A progress report (Cordova, Sandberg, and McConkie, 1970) describes the general findings in the first year of the investigation.

Correlations and comparisons between the Earth-based radar observations, IR observations, and other data will be plotted on photomaps produced from the mapping and panoramic cameras. In addition, the Apollo photography will be used to improve the classifications of the anomalous IR and radar features. The three sets of Earth-based data have already been obtained. The IR (11 μm) data (ref. 29-112) were obtained during a total lunar eclipse. More than a thousand thermally anomalous regions with an unusually high population of exposed boulders have been identified (ref. 29-113). The 70-cm radar backscatter observations made at the same resolution as the IR measurements show regions of anomalous backscatter. These regions have been explained as roughness caused by the boulders on the surface and below the surface. The high-resolution 3.8-cm radar backscatter measurements (ref. 29-114) reveal in great detail regions of anomalous radar backscatter. At this short radar wavelength, small-scale surface and subsurface roughness and boulders less than the order of 10 cm are responsible for the anomalous returns. Previous studies have revealed strong correlation between these three data sets (refs. 29-115 to 29-117). The strongest anomalies (anomalous at all three wavelengths) correspond to features interpreted geologically as young Copernican craters. There are, however, many combinations of enhancements from IR only, 70-cm radar only, 3.8-cm radar only, or combinations of two of these types but not a third. The variation of intensity in all combinations indicates a very complex set of features. These data provide information about the surface on a centimeter- and meter-sized scale although the basic instrumental resolution was 2 to 15 km. The Apollo orbital photography and observations at the landing sites, used in conjunction with the remote sensing data, can significantly improve geologic and geophysical interpretations of lunar surface conditions.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Apollo 16 preliminary science report (NASA SP 315)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Aeronautics and Space Administration","publisherLocation":"Washington, D.C.","usgsCitation":"Zisk, S., Masursky, H., Milton, D., Schaber, G.G., Shorthill, R., and Thompson, T., 1972, Photogeology: Part W: Apollo 16 landing site: summary of Earth-based remote sensing data, chap. of Apollo 16 preliminary science report (NASA SP 315), p. 29-105-29-110.","productDescription":"6 p.","startPage":"29-105","endPage":"29-110","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":266619,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266618,"type":{"id":11,"text":"Document"},"url":"https://www.hq.nasa.gov/alsj/a16/as16psr.pdf"}],"otherGeospatial":"Moon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5107ac1be4b0df796f216e92","contributors":{"authors":[{"text":"Zisk, S.H.","contributorId":35311,"corporation":false,"usgs":true,"family":"Zisk","given":"S.H.","email":"","affiliations":[],"preferred":false,"id":472517,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Masursky, Harold","contributorId":94304,"corporation":false,"usgs":true,"family":"Masursky","given":"Harold","email":"","affiliations":[],"preferred":false,"id":472521,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Milton, D.J.","contributorId":44121,"corporation":false,"usgs":true,"family":"Milton","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":472518,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schaber, G.

The sculpture is particularly well developed in the highlands southwest of the basin, where individual segments have lengths measured in tens of kilometers. THe origin of the ridges and troughs, whether by deposition and impact scoring by fluidized clouds of ejecta from the Imbrium Basin or by faulting and volcanism during and subsequent to basin formation, is controversial.

The most striking feature of the region is the extremely low albedo of the area mapped as Eld in the western half of the map. The low albedo is believed to be caused by a thin layer of pyroclastic volcanic material at the surface. Another notable feature is the fresh-appearing ridges that cross the mare and the adjacent terra. The fine-braided texture of these ridges contrasts markedly with the rounded, subdued topography more common to such features, an indication that the ridges here may be unusually young. Also evident is a well-exposed succession of marelike plains units, which probably represent different stages in the filling of the Serenitatis basin. Several sets of rilles are present; most are roughly tangential to the basin and terminate against the different plains units according to the relative ages. In the northwest corner of the map is a relatively fresh volcanic crater chain (Cch) from which material appears to have been ejected over the surrounding terrain, forming rays of volcanic ejecta. The area thus includes an unusually wide variety of lunar features.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Apollo 15 preliminary science report (NASA SP-289)","largerWorkSubtype":{"id":1,"text":"Federal Government Series"},"language":"English","publisher":"National Aeronautics and Space Administration","publisherLocation":"Washington, D.C.","usgsCitation":"Carr, M.H., 1972, Orbital-science investigation: Part H: sketch map of the region around the candidate Littrow Apollo landing sites, chap. of Apollo 15 preliminary science report (NASA SP-289), p. 25-63-25-65.","productDescription":"3 p.","startPage":"25-63","endPage":"25-65","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":265599,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":265598,"type":{"id":11,"text":"Document"},"url":"https://www.hq.nasa.gov/alsj/a15/as15psr.pdf"}],"otherGeospatial":"Moon","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50f294bae4b0c9e41dd3ab8a","contributors":{"authors":[{"text":"Carr, M.
