    Styles of volcanism on venus: new arecibo high resolution radar data (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-20
    Description: Arecibo high-resolution (1.5 to 2 km) radar data of Venus for the area extending from Beta Regio to western Eisila Regio provide strong evidence that the mountains in Beta and Eisila Regiones and plains in and adjacent to Guinevere Planitia are of volcanic origin. Recognized styles of volcanism include large volcanic edifices on the Beta and Eisila rises related to regional structural trends, plains with multiple source vents and a mottled appearance due to the ponding of volcanic flows, and plains with bright features surrounded by extensive quasi-circular radar-dark halos. The high density of volcanic vents in the plains suggests that heat loss by abundant and widely distributed plains volcanism may be more significant than previously recognized. The low density of impact craters greater than 15 km in diameter in this region compared to the average density for the higher northern latitudes suggests that the plains have a younger age.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campbell, D B -- Head, J W -- Senske, D A -- Fisher, P C -- Hine, A A -- Harmon, J K -- New York, N.Y. -- Science. 1989 Oct 20;246(4928):373-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17747920" target="_blank"〉PubMed〈/a〉

    Evidence for divergent plate-boundary characteristics and crustal spreading on venus (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-12-04
    Description: Detailed examination of the topography and morphology of western Aphrodite Terra reveals numerous features that are similar to terrestrial divergent plate-boundary characteristics. Individual domains between fracturezone-like discontinuities contain a variety of bilaterally symmetrical topographic elements that suggest that topographic features have been created at rise crests, rifted and separated, and moved laterally to their present symmetrical positions. The topographic and morphologic similarities, together with strikingly similar mirror-image map patterns on both sides of the rise axis, suggest that western Aphrodite Terra shares the characteristics of oceanic divergent plate boundaries, and is the site of crustal spreading on Venus. Topographic profiles are consistent with spreading rates of the order of several centimeters per year.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Head, J W 3rd -- Crumpler, L S -- New York, N.Y. -- Science. 1987 Dec 4;238(4832):1380-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17800565" target="_blank"〉PubMed〈/a〉

    The color of the surface of venus (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-12
    Description: Multispectral images of the basaltic surface of Venus obtained by Venera 13 were processed to remove the effects of orange-colored incident radiation resulting from interactions with the thick Venusian atmosphere. At visible wavelengths the surface of Venus appears dark and without significant color. High-temperature laboratory reflectance spectra of basaltic materials indicate that these results are consistent with mineral assemblages bearing either ferric or ferrous iron. A high reflectance in the near-infrared region observed at neighboring Venera 9 and 10 sites, however, suggests that the basaltic surface material contains ferric minerals and thus may be relatively oxidized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pieters, C M -- Head, J W -- Pratt, S -- Patterson, W -- Garvin, J -- Barsukov, V L -- Basilevsky, A T -- Khodakovsky, I L -- Selivanov, A S -- Panfilov, A S -- Gektin, Y M -- Narayeva, Y M -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1379-83.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17755059" target="_blank"〉PubMed〈/a〉
