Scientific objectives, mission constraints, analysis of alternative systems, and the rationale for final choice are presented. Severe financial constraints ruled out the best technical alternative for flyby imaging, a film/readout system, or even significant re-design of previous Mariner vidicon camera/tape recorder systems.</p><p>The final selection was a vidicon camera quite similar to that used for Mariner Mars 1971, but with the capability of real time transmission during the Venus and Mercury flybys. Real time data return became possible through dramatic increase in the communications bandwidth at only modest sacrifice in the quality of the returned pictures. Two identical long focal length cameras (1500 mm) were selected and it will be possible to return several thousand pictures from both planets at resolutions ranging from equivalent to Earthbased to tenths of a kilometer at encounter. Systematic high resolution ultraviolet photography of Venus is planned after encounter in an attempt to understand the nature of the mysterious ultraviolet markings and their apparent 4- to 5-day rotation period. Full disk coverage in mosaics will produce pictures of both planets similar in quality to Earthbased telescopic pictures of the Moon. The increase of resolution, more than three orders of magnitude, will yield an exciting first look at two planets whose closeup appearance is unknown.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0019-1035(71)90071-6","issn":"00191035","usgsCitation":"Murray, B.C., Belton, M.J., Danielson, G.E., Davies, M.E., Kuiper, G.P., O’Leary, B.T., Suomi, V., and Trask, N., 1971, Imaging of Mercury and Venus from a flyby: Icarus, v. 15, no. 2, p. 153-173, https://doi.org/10.1016/0019-1035(71)90071-6.","productDescription":"21 p.","startPage":"153","endPage":"173","numberOfPages":"21","costCenters":[],"links":[{"id":219346,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3883e4b0c8380cd615c6","contributors":{"authors":[{"text":"Murray, B.

The amount of meteoritic component may be either a fortuitous residuum from the object which produced the 12033 material as crater ejecta, or 12033 may consist of a mixture of an exotic component with the local soil in approximately 41:59 proportions.

The records were collected arid computed by the Water Resources Division of the U.S. Geological Survey under the direction of W. E. Hale, district chief. These data represent that portion of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in New Mexico. Through September 30, 1960, the records of discharge and stage of streams and canals and contents and stage of lakes or reservoirs were published in an annual series of U.S. Geological Survey water-supply papers entitled II Surface Water Supply of the United States.\" Beginning with the 1961 water year, surface-water records have been released by the Geological Survey in annual reports on a State-boundary basis. Distribution of these reports is limited; they are designed primarily for rapid release of data shortly after the end of the water year to meet local needs. The discharge and reservoir storage records for 1961-65 also are published in a Geological Survey water-supply paper series entitled \"Surface Water Supply of the United States 1961-65.\" There will

A map of the subsurface extent of the mafic rocks, based on the intricate magnetic patterns, shows that the rocks form a long, semicontinuous block, averaging 40 mi wide and consisting mainly of a sequence of layered flows. This sequence is probably fault-bounded and has been tilted up along the margins, where the linearity of the anomalies indicates steeper dips. The associated clastic rocks, indicated by a smoother magnetic pattern, occur in basins along both sides of the mafic belt and in grabens and a series of axial basins on the upper surface of the block. The well-defined outliers of flows marginal to the main block and the truncation of some of the outermost flow units along a diagonal boundary striking at an angle to them suggest that the present boundaries of the block are postdepositional structural features. The basins and the edges of the block appear to have controlled later, largely vertical movement in the overlying Paleozoic and younger sedimentary cover. Calculated models based on coincident magnetic and detailed gravity profiles along typical cross sections of the midcontinent gravity high show that the block of mafic rocks is steep-sided and as much as several miles thick. The free-air gravity anomaly, which consists of a large positive maximum flanked by minima, averages very close to zero, indicating that this major crustal feature is regionally compensated, although locally each of its components shows a large departure from equilibrium. Remanent magnetization is a primary factor in the interpretation of the magnetic data. Magnetic property studies of Keweenawan mafic rocks in the Lake Superior region show that remanent magnetization may be five times the magnetization induced by the present Earth's field and differs from it radically in direction. This magnetization was acquired before the flows were tilted into their present positions. A computed magnetic profile shows that a trough of flows with such a magnetization and inward-dipping limbs can account for the observed persistent lows along the western edge of the block, the relatively low magnetic values along the axis of the block, and the large positive anomaly along the eastern side of the block. Flows as much as 1 mi thick near the base of the sequence have a remanent magnetization with a nearly opposite polarity. This reverse polarity has been measured on both sides of Lake Superior and is probably also present farther south, particularly in Iowa where the outer units of the block in an area north of Des Moines give rise to a prominent magnetic low. The axis of this long belt of Keweenawan mafic rocks cuts discordantly through the prevailing east-west-trending fabric of the older Precambrian terrane from southern Kansas to Lake Superior. This belt has several major left-lateral offsets, one of which produces a complete hiatus in the vicinity of the 40th parallel where an east-west transcontinental rift or fracture zone has been proposed. The axial basins of clastic rocks are outlined by linear magnetic anomalies and show a concordant relation to the structure of the mafic flows. These basins are oriented at an angle to the main axis, suggesting that the entire feature originated as a major rift composed of a series of short, linear, <i>en echelon</i> segments with offsets similar to the transform faults characterizing the present mid-ocean rift system. This midcontinent rift may well have been part of a Keweenawan global rift system with initial offsets consisting of transform faults along pre-existing fractures, but apparently it never fully developed laterally into an ocean basin, and the upwelling mafic material was localized along a relatively narrow belt.","language":"English","publisher":"Geological Society of

Size of branch was defined by branch order, or its position in the hierarchy of tributaries. It was found that, as in river drainage nets, there is a definite logarithmic relation between branch order and lengths and numbers. This definite relation is quantitatively comparable, within limits, among river networks, tree branching systems, and several random-walk models in both two and three dimensions. Such a relation appears to be the most probable under the applicable constraints. Moreover the most probable arrangement appears to minimize the total length of all stems in the branching system within other constraints and so, to that extent, achieves a certain efficiency.</p>","largerWorkTitle":"Journal of Theoretical Biology","language":"English","publisher":"Elsevier","doi":"10.1016/0022-5193(71)90192-5","issn":"00225193","usgsCitation":"Leopold, L.B., 1971, Trees and streams: The efficiency of branching patterns: Journal of Theoretical Biology, v. 31, no. 2, p. 339-354, https://doi.org/10.1016/0022-5193(71)90192-5.","productDescription":"16 p.","startPage":"339","endPage":"354","costCenters":[],"links":[{"id":219004,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb7a9e4b08c986b3273f1","contributors":{"authors":[{"text":"Leopold, Luna Bergere","contributorId":93884,"corporation":false,"usgs":true,"family":"Leopold","given":"Luna","email":"","middleInitial":"Bergere","affiliations":[],"preferred":false,"id":358819,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Calcite does not yield the {015} diffraction maximum. The {006} diffraction maximum is lacking over most of the range of composition of calcite. Calcite has compositions from CaCO<sub>3</sub><span>&nbsp;</span>to Ca<sub>0.5</sub>Mg<sub>0.5</sub>CO<sub>3</sub>.

The Ca-Mg carbonates form in isotopic equilibrium and thermodynamic disequilibrium from dispersion of Ca<sup>2+</sup>-rich water into CO<sub>3</sub><sup>2−</sup>-rich water within the alluvium. The stable isotope data suggest that all the Mg-rich carbonates are primary precipitates and not a result of Mg-substitution in precursor CaCO<sub>3</sub>.

Analysis of these materials by microscopy and by gas chromatography and mass spectrometry shows the presence of constituents of both low and high molecular weights. The former include CH<sub>4</sub>, C<sub>2</sub>H<sub>6</sub>, C<sub>3</sub>H<sub>8</sub><span>&nbsp;</span>and possibly C<sub>4</sub>H<sub>10</sub><span>&nbsp;</span>as well as CO, CO<sub>2</sub>, H<sub>2</sub>O, N<sub>2</sub><span>&nbsp;</span>and H<sub>2</sub>. High molecular weight components are dominantly n-alkanes and isoprenoid hydrocarbons. The n-alkanes range from at least n-C<sub>10</sub><span>&nbsp;</span>to n-C<sub>33</sub>. Concentrations of n-alkanes larger than n-C<sub>17</sub><span>&nbsp;</span>decrease regularly with increasing carbon number. An homologous series of isoprenoid hydrocarbons ranging from at least C<sub>14</sub><span>&nbsp;</span>to C<sub>20</sub><span>&nbsp;</span>is present in unusually high concentrations. Pristane (C<sub>19</sub>) is most abundant, and C<sub>17</sub><span>&nbsp;</span>isoprenoid is least abundant. The molecular composition and distribution of hydrocarbons suggest biological precursors for these components.</p><p>Consideration of data provided by freezing, crushing and heating experiments suggests that the pressures at the time these in part supercritical fluids were trapped probably exceeded 30–40 atm, and the minimum trapping temperature was about 120–160°C. Both primary and secondary inclusions apparently containing only organic materials were trapped by the growth of the host quartz from aqueous solution. The data obtained neither prove nor preclude Precambrian, Paleozoic or younger sources for the organic materials.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(71)90112-8","issn":"00167037","usgsCitation":"Kvenvolden, K., and Roedder, E., 1971, Fluid inclusions in quartz crystals from South-West Africa: Geochimica et Cosmochimica Acta, v. 35, no. 12, p. 1209-1229, https://doi.org/10.1016/0016-7037(71)90112-8.","productDescription":"20 p.","startPage":"1209","endPage":"1229","costCenters":[],"links":[{"id":219523,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              7.03125,\n              -37.71859032558814\n            ],\n            [\n              28.828124999999996,\n              -37.71859032558814\n            ],\n            [\n              28.828124999999996,\n              -13.2399454992863\n            ],\n            [\n              7.03125,\n              -13.2399454992863\n            ],\n            [\n              7.03125,\n              -37.71859032558814\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"35","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1276e4b0c8380cd542f5","contributors":{"authors":[{"text":"Kvenvolden, K.A.","contributorId":80674,"corporation":false,"usgs":true,"family":"Kvenvolden","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":358588,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roedder, E.","contributorId":100986,"corporation":false,"usgs":true,"family":"Roedder","given":"E.","affiliations":[],"preferred":false,"id":358589,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
