Friction of rocks
J. Byerlee
1978, Pure and Applied Geophysics PAGEOPH (116) 615-626
Experimental results in the published literature show that at low normal stress the shear stress required to slide one rock over another varies widely between experiments. This is because at low stress rock friction is strongly dependent on surface roughness. At high normal stress that effect is diminished and the...
Mars synthetic topographic mapping
S.S.C. Wu
1978, Icarus (33) 417-440
Topographic contour maps of Mars are compiled by the synthesis of data acquired from various scientific experiments of the Mariner 9 mission, including S-band radio-occulation, the ultraviolet spectrometer (UVS), the infrared radiometer (IRR), the infrared interferometer spectrometer (IRIS) and television imagery, as well as Earth-based radar information collected at Goldstone,...

1978, Earth and Planetary Science Letters (41) 67-76
The diagenesis of the hydroxy amino acids serine and threonine in foraminiferal tests has been investigated. The decomposition pathways of these amino acids are complex; the principal reactions appear to be dehydration, aldol cleavage and decarboxylation. Stereochemical studies indicate that the...
Cobalt and scandium partitioning versus iron content for crystalline phases in ultramafic nodules
W.E. Glassley, D.Z. Piper
1978, Earth and Planetary Science Letters (39) 173-178
Fractionation of Co and Sc between garnets, olivines, and clino- and orthopyroxenes, separated from a suite of Salt Lake Crater ultramafic nodules that equilibrated at the same T and P, is strongly dependent on Fe contents. This observation suggests that petrogenetic equilibrium models of...
Distribution of rutile in metamorphic rocks and implications for placer deposits
R. Goldsmith, E. R. Force
1978, Mineralium Deposita (13) 329-343
Pelitic units in the eastern Great Smoky Mountains of the North Carolina Blue Ridge contain rutile grains only in kyanite and higher zones. Adjacent non-pelitic rocks do not contain rutile at kyanite grade but commonly contain sphene. Detrital rutile breaks down at metamorphic grades lower than those at which metamorphic...
Time-dependent friction and the mechanics of stick-slip
James H. Dieterich
1978, Pure and Applied Geophysics PAGEOPH (116) 790-806
Time-dependent increase of static friction is characteristic of rock friction undera variety of experimental circumstances. Data presented here show an analogous velocity-dependent effect. A theor of friction is proposed that establishes a common basis for static and sliding friction. Creep at points of contact causes increases in friction that are...

Silicate liquid immiscibility in magmas and in the system K2O-FeO-AI2O3-SiO2: An example of serendipity
E. Roedder
1978, Geochimica et Cosmochimica Acta (42) 1597-1617
The concept of silicate liquid immiscibility was invoked early in the history of petrology to explain certain pairs of compositionally divergent rocks, but. as a result of papers by Greig (Am. J. Sci.13, 1–44, 133–154) and Bowen (The Evolution of the Igneous Rocks), it fell into disfavor for many years....

Vesicularity of basalt erupted at Reykjanes Ridge crest
W. A. Duffield
1978, Nature (274) 217-220
Average vesicularity of basalt drilled at three sites on the west flank of the Reykjanes Ridge increases with decreasing age. This change apparently records concomitant decrease in water depth at the ridge crest where the basalt was erupted and suggests substantial upward growth of the crest during the past 35...
