  • Walker, David, 1946-; Stolper, Edward M.; Hays, J. F. (Pergamon Press, 1979)
    The volumetrically abundant basalts on the earth, its moon, and the eucrite parent planet all have chemical compositions that are controlled to a large extent by dry, low-pressure, crystal-liquid equilibria. Since this ...
  • Lofgren, Gary E.; Lofgren, Ellen M. (Lyndon B. Johnson Space Center, 1981-08)
    Megascopic descriptions of 133 basaltic rocks returned from the Moon are presented along with photographs of each rock and its thin section, if available. The major and trace element chemistry of each is included wherever ...
  • Boyce, Jeremy W.; Treiman, Allan H.;; Guan, Yunbin; Ma, Chi; Eiler, John M.; Gross, Juliane; Greenwood, James P.; Stolper, Edward M. (American Association for the Advancement of Science, 2015-09-25)
    The Moon contains chlorine that is isotopically unlike that of any other body yet studied in the Solar System, an observation that has been interpreted to support traditional models of the formation of a nominally hydrogen-free ...
  • Walker, David, 1946-; Powell, M. A.; Lofgren, Gary E.; Hays, J. F. (Pergamon Press, 1978)
    Crystallization textures produced experimentally from eucrite Stannern show variations as a function of initial melting temperature (T 0) and linear cooling rate.
  • Schultz, Peter H., 1944-; Spudis, Paul D. (Pergamon Press, 1979)
    Basaltic volcanism clearly exposed as dark surface units may represent only the last stages of continuous volcanic activity during the first 1.5 b.y. of lunar history. Between 3.0 and 3.9 AE, part of this record has been ...
  • Lofgren, Gary E.; Donaldson, Colin H.; Williams, Richard J.; Mullins, Jr., Oscar; Usselman, Thomas M. (Pergamon Press, 1974)
    An analog of the Apollo 15 quartz-normative basalts (also called pyroxene-phyric basalts) has been experimentally crystallized at a variety of linear cooling rates between 1250 and 1°C/hr at one atmosphere total pressure ...
  • Lofgren, Gary E.; Donaldson, Colin H.; Usselman, Thomas M. (Pergamon Press, 1975)
    The quartz-normative (QN) basalts collected at the Apollo 15 site have a unique and consistent bulk chemistry, but display a systematic variation in phenocryst morphology and matrix texture. Experimental crystallization ...
  • Needham, Debra H.; Kring, David A. (David Allen) (Elsevier, 2017-11-15)
    We investigated the volume of mare basalt and the mass of volatiles released from the Moon as a function of time to determine how the lunar atmosphere may have been affected by more intense volcanic activity early in lunar history
  • Nabelek, Peter I.; Taylor, Lawrence A.; Lofgren, Gary E. (Pergamon Press, 1978)
    Dynamic crystallization experiments were conducted in order to determine the conditions necessary to produce poikilitic, intersertal and subophitic textures from a plagioclase-rich basaltic melt.
  • Usselman, Thomas M.; Lofgren, Gary E. (Pergamon Press, 1976)
    The high-titanium mare basalts show a wide diversity of textures and paragenetic sequences. The order of appearance of ilmenite and pyroxene is shown to be very sensitive to oxygen fugacity within the lunar range, using ...
  • Schaal, Rand Brian; Hörz, Friedrich, 1940- (Pergamon Press, 1977)
    Lonar Crater (India) basalt and lunar basalt 75035 were shock loaded under controlled laboratory conditions up to 1000 kbar, the highest peak pressure obtained to date in successful shock recovery; most of the experiments ...
  • Spudis, Paul D.; Ryder, Graham; Taylor, G. Jeffrey, 1944-; McCormick, K. A.; Keil, Klaus; Grieve, Richard A. F. (Lunar and Planetary Institute, 1991)
    The low-K Fra Mauro (LKFM) basalt composition is common among the melt breccias sampled by the Apollo missions to the lunar highlands. We analyzed major and minor elements in mineral clasts in the lunar LKFM impact melts ...
  • Gibson, Everett K.; Usselman, Thomas M.; Morris, Richard V. (Pergamon Press, 1976)
    Thirty-two Apollo 17 mare basalts have been analyzed for their total sulfur and metallic iron abundances.
  • Gong, Shengxia; Wieczorek, Mark A.; Nimmo, Francis; Kiefer, Walter S.;; Head, James W.; Huang, Chengli; Smith, David E.; Zuber, Maria T. (American Geophysical Union, 2016-05-11)
    A new method of determining the thickness of mare basalts on the Moon is introduced that is made possible by high‐resolution gravity data acquired from NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission.
