Lamprophyres, Basanites, and Basalts of the Western Mexican Volcanic Belt: Volatile Contents and a Vein-Wallrock Melting Relationship

Maria, Anton H.; Luhr, James F. (2008)

We present geochemical data for Quaternary basalts, basanites, and lamprophyres within the Colima and Mascota volcanic fields at the western end of the Mexican Volcanic Belt. On the basis of data for 11 whole-rock samples ...
The Leedey, Oklahoma, chondrite: Fall, petrology, chemistry and an unusual Fe,Ni-FeS inclusion

McCoy, Timothy J.; Ehlmann, A. J.; Moore, C. B. (1997)
Magnesium-rich crustal compositions on Mercury: Implications for magmatism from petrologic modeling

Stockstill-Cahill, Karen R.; McCoy, Timothy J.; Nittler, Larry R.; Weider, Shoshana Z.; Hauck, Steven A. (2012)

We have conducted petrologic modeling of MESSENGER-derived compositions and analog compositions to gain a better understanding of the petrogenesis of the crust of Mercury. Analog compositions included a 1425°C partial melt ...
Major-element abundances on the surface of Mercury: Results from the MESSENGER Gamma-Ray Spectrometer

Evans, Larry G.; Peplowski, Patrick N.; Rhodes, Edgar A.; Lawrence, David J.; McCoy, Timothy J.; Nittler, Larry R.; Solomon, Sean C.; Sprague, Ann L.; Stockstill-Cahill, Karen R.; Starr, Richard D.; Weider, Shoshana Z.; Boynton, William V.; Hamara, David K.; Goldsten, John O. (2012)

Orbital gamma-ray measurements obtained by the MESSENGER spacecraft have been analyzed to determine the abundances of the major elements Al, Ca, S, Fe, and Na on the surface of Mercury. The Si abundance was determined and ...
The Major-Element Composition of Mercury s Surface from MESSENGER X-ray Spectrometry

Nittler, Larry R.; Starr, Richard D.; Weider, Shoshana Z.; McCoy, Timothy J.; Boynton, William V.; Ebel, Denton S.; Ernst, Carolyn M.; Evans, Larry G.; Goldsten, John O.; Hamara, David K.; Lawrence, David J.; McNutt, Ralph L.; Schlemm, Charles E.; Solomon, Sean C.; Sprague, Ann L. (2011)

X-ray fluorescence spectra obtained by the MESSENGER spacecraft orbiting Mercury indicate that the planet s surface differs in composition from those of other terrestrial planets. Relatively high Mg/Si and low Al/Si and ...
Martian parent craters for the SNC meteorites

Mouginis-Mark, P. J.; McCoy, Timothy J.; Taylor, G. J.; Keil, K. (1992)
Metal-silicate partitioning of tungsten at high pressure and temperature: Implications for equilibrium core formation in Earth

Cottrell, Elizabeth; Walter, Michael J.; Walker, David (2009)

Tungsten partitioning between liquid metal and liquid silicate, D(W), from 1723-2673 K, 0.5-18 GPa, and over a wide range of metal and silicate compositions provides constraints on planetary core formation models. We find ...
Metamorphic reworking of a high pressure-low temperature mélange along the Motagua fault, Guatemala: A record of Neocomian and Maastrichtian transpressional tectonics

Brueckner, Hannes K.; Avé Lallemant, Hans G.; Sisson, Virginia B.; Harlow, George E.; Hemming, Sidney R.; Martens, Uwe; Tsujimori, Tatsuki; Sorensen, Sorena S. (2009)

The Guatemala suture zone is a major east-west left-lateral strike slip boundary that separates the North American and Caribbean plates in Guatemala. The Motagua fault, the central active strand of the suture zone, underwent ...
Meteorites and the Smithsonian Institution

Clarke, Roy S., Jr.; Plotkin, Howard; McCoy, Timothy J. (Geological Society, 2006)
Meteorites on Mars observed with the Mars Exploration Rovers

Schroeder, C.; Rodionov, D. S.; McCoy, Timothy J.; Jolliff, B. L.; Gellert, R.; Nittler, L. R.; Farrand, W. H.; Johnson, J. R.; Ruff, S. W.; Ashley, J. W.; Mittlefehldt, D. W.; Herkenhoff, Kenneth E.; Fleischer, I.; Haldemann, A. F. C.; Klingelhöfer, Göstar; Ming, D. W.; Morris, R. V.; de Souza, P. A.; Squyres, Steven W.; Weitz, Catherine M.; Yen, A. S.; Zipfel, J.; Economou, T. (2008)

Reduced weathering rates due to the lack of liquid water and significantly greater typical surface ages should result in a higher density of meteorites on the surface of Mars compared to Earth. Several meteorites were ...
Meteoritic parent bodies: Their number and identification

Burbine, Thomas H.; McCoy, Timothy J.; Meibom, Anders; Gladman, Brett; Keil, Klaus (University of Arizona Press, 2002)
Mineral evolution

Hazen, Robert M.; Papineau, Dominic; Bleeker, Wouter; Downs, Robert T.; Ferry, John M.; McCoy, Timothy J.; Sverjensky, Dimitri A.; Yang, Hexiong (2008)

The mineralogy of terrestrial planets evolves as a consequence of a range of physical, chemical, and biological processes. In pre-stellar molecular clouds, widely dispersed microscopic dust particles contain approximately ...
Mineralogic constraints on sulfur-rich soils from Pancam spectra at Gusev Crater, Mars

Johnson J.R.; Bell, James F., III; Cloutis E.; Staid M.; Farrand W.H.; McCoy, Timothy J.; Rice, Mary E.; Wang A.; Yen A. (2007)
Mineralogical Evolution of Meteorites

McCoy, Timothy J. (2010)

The approximately 250 mineral species found in meteorites record the earliest stages of the birth of our solar system. Refractory minerals that formed during the violent deaths of other stars and during condensation of our ...
Mineralogy of volcanic rocks in Gusev Crater, Mars: Reconciling Mossbauer, Alpha Particle X-ray spectrometer, and Miniature Thermal Emission Spectrometer spectra

McSween, Harry Y.; Ruff, S. W.; Morris, R. V.; Gellert, R.; Klingelhöfer, Göstar; Christensen, Philip R.; McCoy, Timothy J.; Ghosh, A.; Moersch, J. M.; Cohen, B. A.; Rogers, A. D.; Schroder, C.; Squyres, Steven W.; Crisp, J.; Yen, A. (2008)
Minor element evidence that asteroid 433 Eros is a space-weatered ordinary chondrite parent body
