Abstract: Earth upper mantle phase change instability, discussing temperature gradient, transformation influence on fluid, olivine-spinel phase flow patterns and tectonics NASA Center: NASA (non Center Specific) Publication Year: 1970 Added to NTRS: 2004-11-03 Accession Number: 70A41895; Document ID: 19700065779 Crustal deformation: Earth vs Venus Author(s): Turcotte, D. L. Abstract: It is timely to consider the possible tectonic regimes on Venus both in terms of what is known about Venus and in terms of deformation mechanisms operative on the earth. Plate tectonic phenomena dominate tectonics on the ... NASA Center: NASA (non Center Specific) Publication Year: 1989 Added to NTRS: 2004-11-03 Accession Number: 90N12450; Document ID: 19900003134 Numerical calculations of the cross-section for the accretional capture of the moon by the earth Author(s): Nordmann, J. C.; Turcotte, D. L. Abstract: If a primary body is increasing in mass the hyperbolic orbit of a secondary body can become an elliptic orbit. In order to determine the cross-section for the accretional capture of the moon by the earth, a series of ... NASA Center: NASA (non Center Specific) Publication Year: 1977 Added to NTRS: 2004-11-03 Accession Number: 78A41555; Document ID: 19780057646 Thermal stresses in planetary elastic lithospheres Author(s): Turcotte, D. L. Abstract: The role of thermal stresses in the tectonics of the moon is reexamined in this paper. A model is used that considers a spherical elastic shell overlying a fluid core. It is shown that the thermal stresses generated by ... NASA Center: NASA (non Center Specific) Publication Year: 1983 Added to NTRS: 2004-11-03 Accession Number: 83A21292; Document ID: 19830040074 On the evolution of the lunar orbit Author(s): Turcotte, D. L.; Cisne, J. L.; Nordmann, J. C. Abstract: It is generally accepted that the earth-moon separation is at present increasing due to tidal dissipation. Values for the corresponding lunar deceleration and the related slowing of the earth's rotation are obtained from ... NASA Center: NASA (non Center Specific) Publication Year: 1977 Added to NTRS: 2004-11-03 Accession Number: 77A23727; Document ID: 19770040875 Stress accumulated mechanisms on strike-slip faults Author(s): Turcotte, D. L. Abstract: The tectonic framework causing seismicity on the San Andreas and North Anatolian faults can be understood in terms of plate tectonics. However, the mechanisms responsible for the distribution of seismicity in space and time ... NASA Center: NASA (non Center Specific) Publication Year: 1980 Added to NTRS: 2004-11-03 Accession Number: 82A41550; Document ID: 19820058015 A renormalization group model for the stick-slip behavior of faults Author(s): Smalley, R. F., Jr.; Turcotte, D. L.; Solla, S. A. Abstract: A fault which is treated as an array of asperities with a prescribed statistical distribution of strengths is described. For a linear array the stress is transferred to a single adjacent asperity and for a two dimensional ... NASA Center: NASA (non Center Specific) Publication Year: 1983 Added to NTRS: 2004-11-03 Accession Number: 84N18782; Document ID: 19840010714; Report Number: CONTRIB-766, NAS 1.26:173362, NASA-CR-173362 Origin and thermal evolution of Mars Author(s): Schubert, G.; Solomon, S. C.; Turcotte, D. L.; Drake, M. J.; Sleep, N. H. Abstract: The thermal evolution of Mars is governed by subsolidus mantle convection beneath a thick lithosphere. Models of the interior evolution are developed by parameterizing mantle convective heat transport in terms of mantle ... NASA Center: Goddard Space Flight Center, Jet Propulsion Laboratory, Johnson Space Center Publication Year: 1992 Added to NTRS: 2004-11-03 Accession Number: 93A27857; Document ID: 19930043860 A heat-pipe mechanism for volcanism and tectonics on Venus Author(s): Turcotte, D. L. Abstract: A heat-pipe mechanism is proposed for the transport of heat through the lithosphere of Venus. This mechanism allows the crust and lithosphere on Venus to be greater than 150 km thick. A thick basaltic crust on Venus is ...

L.; Torrance, K. E.; Hsui, A. T. Abstract: The computer is used to solve for thermal convection within the earth's mantle. A review of the knowledge of surface displacements and of the present understanding of the mantle and its relevant physical and chemical ...
