Shock melts in QUE 94411, Hammadah al Hamra 237 and Bencubbin: Remains of the missing matrix

Meibom, A.; Righter, K.; Chabot, N. Dehn; Antignano, A. A.; McCoy, Timothy J.; Krot, A. N.; Zolensky, M. E.; Petaev, Michail I.; Keil, K. (2005)
Signatures of the Martian atmosphere in glass of the Zagami meteorite

Marti, K.; Kim, J. S.; Thakur, A. N.; McCoy, Timothy J.; Keil, K. (1995)
Soil phosphorus fractionation and nutrient dynamics along the Cooloola coastal dune chronosequence, southern Queensland, Australia

Chen, C. R.; Hou, E. Q.; Condron, L. M.; Bacon, G.; Esfandbod, M.; Olley, J.; Turner, Benjamin L. (2015)

The amounts and forms of soil phosphorus (P) follow predictable patterns during long-term pedogenesis, but have rarely been examined along subtropical chronosequences. We quantified changes in soil nutrient stocks, foliar ...
Spectra of extremely reduced assemblages: Implications for Mercury

Burbine, Thomas H.; McCoy, Timothy J.; Nittler, Larry R.; Benedix, Gretchen K.; Cloutis, Edward A.; Dickinson, Tamara L. (2002)

We investigate the possibility that Mercury's crust is very reduced with FeO concentrations of less than 02DC0.1 wt%. We believe that such a surface could have a composition of enstatite, plagioclase, diopside, and ...
Spectral properties of angrites

Burbine, T. H.; McCoy, Timothy J.; Lucey, Paul G. (2006)
Spectral, mineralogical, and geochemical variations across Home Plate, Gusev Crater, Mars indicate high and low temperature alteration

Schmidt, M. E.; Farrand, W. H.; Johnson, J. R.; Schröder, C.; Hurowitz, J. A.; McCoy, Timothy J.; Ruff, S. W.; Arvidson, Raymond E.; Des Marais, D. J.; Lewis, K. W.; Ming, D. W.; Squyres, Steven W.; de, Souza,Jr (2009)

Over the last ~ 3 years in Gusev Crater, Mars, the Spirit rover observed coherent variations in color, mineralogy, and geochemistry across Home Plate, an ~ 80 m-diameter outcrop of basaltic tephra. Observations of Home ...
Spectroscopic Observations of Mercury's Surface Reflectance During MESSENGER's First Mercury Flyby

McClintock, William E.; Izenberg, Noam R.; Holsclaw, Gregory M.; Blewett, David T.; Domingue, Deborah L.; Head, James W.; Helbert, Jorn; McCoy, Timothy J.; Murchie, Scott L.; Robinsob, Mark S.; Solomon, Sean C.; Sprague, Ann L.; Vilas, Faith (2008)

During MESSENGER's first flyby of Mercury, the Mercury Atmospheric and Surface Composition Spectrometer made simultaneous mid-ultraviolet to near-infrared (wavelengths of 200 to 1300 nanometers) reflectance observations ...
Spinel-bearing Al-rich chondrules in two chondrite finds from Roosevelt County, New Mexico: Indicators of nebular and parent body processes

McCoy, Timothy J.; Pun, Aurora; Keil, Klaus (1991)
Standards for the U.S. Antarctic meteorite program collection: Preserving outer space in museum space

Welzenbach, L. C.; McCoy, Timothy J.; Righter, K.; Satterwhite, C. E. (2006)
Systematics and evaluation of meteorite classification

Weisberg, M. K.; McCoy, Timothy J.; Krot, A. N. (Univ. of Arizona Press, 2006)
The Tafassasset Primitive Achondrite: Insights into Initial Stages of Planetary Differentiation

Gardner-Vandy, Kathryn G.; Lauretta, Dante S.; Greenwood, Richard C.; McCoy, Timothy J.; Killgore, Marvin; Franchi, Ian A. (2012)

Tafassasset is an exceptional meteorite that has been linked to both the CR chondrites and the primitive achondrites. Because previous evidence suggests it might be a primitive achondrite from a known chondrite type, we ...
The Tatum, New Mexico, chondrite and its silica inclusion

Ehlmann, Arthur; McCoy, Timothy J.; Keil, Klaus (1994)
Technical-Information Products for a National Volcano Early Warning System

Guffanti, Marianne; Brantley, Steven R.; Cervelli, Peter F.; Nye, Christopher J.; Serafino, George N.; Siebert, Lee; Venezky, Dina Y.; Wald, Lisa; (2007)
Theo's Flow, Ontario, Candada: a terrestrial analog for the Martian nakhlite meteorites

Lentz, R. C. F.; McCoy, Timothy J.; Collins, L. E.; Corrigan, Catherine M.; Benedix, Gretchen K.; Taylor, G. J.; Harvey, R. P. (Geological Society of America, 2011)
Thermal and impact histories of reheated group IVA, IVB, and ungrouped iron meteorites and their parent asteroids

Yang, J.; Goldstein, J. I.; Scott, E. R. D.; Michael, J. R.; Kotula, P. G.; Pham, T.; McCoy, Timothy J. (2011)

Abstract- The microstructures of six reheated iron meteorites-two IVA irons, Maria Elena (1935), Fuzzy Creek; one IVB iron, Ternera; and three ungrouped irons, Hammond, Babb's Mill (Blake's Iron), and Babb's Mill (Troost's ...
Thermal and rheological controls on the formation of mafic enclaves or banded pumice

Andrews, Benjamin J.; Manga, Michael (2014)
Thermal histories of IVA stony-iron and iron meteorites: Evidence for asteroid fragmentation and reaccretion

Haack, H.; Scott, E. R. D.; Love, S. G.; Brearley, A. J.; McCoy, Timothy J. (1996)
Thermodynamic constraints on the formation conditions of winonaites and silicate-bearing IAB irons

Variations in the abundances of potassium and thorium on the surface of Mercury: Results from the MESSENGER Gamma-Ray Spectrometer

Peplowski, Patrick N.; Lawrence, David J.; Rhodes, Edgar A.; Sprague, Ann L.; McCoy, Timothy J.; Denevi, Brett W.; Evans, Larry G.; Head, James W.; Nittler, Larry R.; Solomon, Sean C.; Stockstill-Cahill, Karen R.; Weider, Shoshana Z. (2012)

A technique for converting gamma-ray count rates measured by the Gamma-Ray Spectrometer on the MESSENGER spacecraft to spatially resolved maps of the gamma-ray emission from the surface of Mercury is utilized to map the ...
