  • Manka, R. H.; Michel, F. C. (Pergamon Press, 1973)
    In this paper we discuss several new aspects of the acceleration of ions formed in the lunar atmosphere. In particular we will look at the predicted and observed energy spectrum of the ions, the lunar surface potential ...
  • Neukum, Gerhard; Hörz, Friedrich, 1940-; Morrison, Donald A.; Hartung, Jack B. (Pergamon Press, 1973)
    Approximately 10,000 microcraters were investigated using binocular microscope techniques on fifteen Apollo 16 rocks: "crystalline" rocks 60315, 60335, 61156, 62235, 62295, and 68415; "breccias" 60016, 61015, 61175, 66075, ...
  • Lindsay, John F. (John Francis), 1941-2008 (Pergamon Press, 1973)
    The stratigraphy of the few meters of soil exposed on the lunar surface provides a long record of lunar history. Deep cores returned by the Apollo 15 and 16 missions provide the first extensive sampling of this stratigraphy. ...
  • Ridley, W. I.; Reid, Arch M.; Warner, Jeffrey L.; Brown, Roy W.; Gooley, R.; Donaldson, Colin H. (Pergamon Press, 1973)
    Major element analyses have been made of 309 glasses in two Apollo 16 soils, 60501 and 61221. Averages of preferred glass compositions are used as a guide to the nature of the major rock types contributing to these soils.
  • Pearce, G. W.; Strangway, D. W.; Gose, W. A. (Pergamon Press, 1974)
    The magnetic properties of a number of Apollo 17 samples have been measured and confirm that regoliths of mare sites (Apollo 11, 12, 15 valley, and 17 valley) differ markedly from those of highland sites (Apollo 14, 16, ...
  • Unknown author (Lunar Science Institute, 1974)
    Numerous studies on the properties of the moon based on Apollo findings and samples are presented. Topics treated include ages of the lunar nearside light plains and maria, orange material in the Sulpicius Gallus formation ...
  • McCoy, James E.; Criswell, David R. (Pergamon Press, 1974)
    This paper will present evidence from Apollo lunar orbital observations, indicating the existence of solar light scattering from a significant population of lunar particulates extending to altitudes in excess of 100 km. ...
  • Hörz, Friedrich, 1940-; Schneider, Eberhard; Hill, Richard E. (Pergamon Press, 1974)
    A Monte Carlo computer model was developed to simulate impact histories and erosion by single particle abrasion of lunar rock surfaces. Microcrater frequencies derived from lunar rocks were used to calculate magnitude and ...
  • Fryxell, Roald; Heiken, Grant (Pergamon Press, 1974)
    Core samples collected from the lunar regolith have been almost entirely incoherent and loose in consistence. Most have been transported to earth with original features of stratigraphy intact, and disturbance by the sampling ...
  • Taylor, Stuart Ross, 1925-; Jakeš, Petr (Pergamon Press, 1974)
    In this paper we consider the evidence for and the implications of homogeneous accretion of the moon. Inter-element ratios are used to calculate the composition of the highland crust.
  • Warner, Jeffrey L.; Simonds, Charles H.; Phinney, William C. (Pergamon Press, 1974)
    A synthesis of the relevant data concerning lunar highland polymict breccias from the fields of petrography, chemistry, photogeology, and impact studies compels the prediction that the breccias should have homogeneous ...
  • 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 ...
  • Simonds, Charles H.; Phinney, William C.; Warner, Jeffrey L. (Pergamon Press, 1974)
    The Apollo 17 non-mare rock collection consists largely of polymict breccias lithified by impact. These rocks are characterized by a variety of types of lithic clasts, concentrations of siderophile elements that indicate ...
  • Lindsay, John F. (John Francis), 1941-2008 (Pergamon Press, 1974)
    Four dimensional cluster analysis of the grain size parameters (mean, standard deviation, skewness, and kurtosis) of 125 lunar soils from the Apollo 15, 16, and 17 sites has provided a basis for the construction of a general ...
  • Runcorn, S. K. (Pergamon Press, 1974)
    The discovery of positive gravity anomalies over the circular maria by Muller and Sjogren (1968) has been one of the most discussed results of the Apollo lunar exploration program. That the contours of the gravitational ...
  • Phinney, William C.; Warner, Jeffrey L.; Simonds, Charles H. (National Aeronautics and Space Administration, 1974)
    Lunar rocks may be classified into three major groups: (1) coarse-grained igneous rocks, (2) fine-grained igneous rocks, and (3) breccias. Group 1 is interpreted as primitive lunar crustal rocks that display various degrees ...
  • Criswell, David R.; Freeman, John W. (Lunar Science Institute, 1974)
    Deals with solar-wind and magnetospheric interactions with the moon, ancient and present-day lunar surface magnetic and electric fields, the dynamics and evolution of the lunar atmosphere, the lunar record of solar radiation, ...
  • Consortium Indomitable (Smithsonian Astrophysical Observatory, 1974-03-15)
    Geomorphological studies on rock samples from the Apollo 17 lunar landing site are presented.
  • Simonds, Charles H.; Waranius, Frances B.; Heiken, Jody H. (Lunar Science Institute, 1974-11)
    Data pertaining to the collection, processing, and study of lunar samples, and the ways to gain access to that data are described. Data pertaining to the samples includes not only the normally published literature but also ...
  • Consortium Indomitable (Smithsonian Astrophysical Observatory, 1974-11-12)
    Geomorphological studies on rock samples from the Apollo 17 lunar landing site are presented.
