  • Astronaut's guide to terrestrial impact craters 
    Grieve, Richard A. F. (Lunar and Planetary Institute, 1988)
    Impact cratering of the Earth's surface is discussed and compared with lunar craters. Known craters on earth are ordered by location and a few principal facts are given for each crater and the general terrain in which it ...
  • Calculational investigation of impact cratering dynamics: Early time material motions 
    Thomsen, Jeffrey M.; Austin, Michael G.; Ruhl, Stephen F.; Schultz, Peter H., 1944-; Orphal, Dennis L. (Pergamon Press, 1979)
    Early time two-dimensional finite difference calculations of laboratory-scale hypervelocity (6 km/sec) impact of 0.3 g spherical 2024 aluminum projectiles into homogeneous plasticene clay targets were performed and the ...
  • Cratering flow fields: Implications for the excavation and transient expansion stages of crater formation 
    Croft, Steven Kent (Pergamon Press, 1980)
    A Maxwell Z-model cratering flow field originating at non-zero depths-of-burst has been used to calculate theoretical depths and volumes of excavation, hinge radii, ejection angles, and transient structural rim uplifts for ...
  • Detecting a Periodic Signal in the Terrestrial Cratering Record 
    Grieve, Richard A. F.; Sharpton, Virgil L.; Rupert, James D.; Goodacre, Alan K. (Cambridge University Press, 1988)
    Time-series analyses of periodic, random, and a mixture of periodic and random ages indicate that it is difficult to consistently detect a period if age uncertainties are present. This problem is present in real data taken ...
  • Effects of lift force on ejecta transport 
    Pai, S. I.; Menon, S.; Schultz, Peter H., 1944- (Pergamon Press, 1979)
    The possible effects of lift on individual ejecta trajectories after an impact event are examined, considering a dimensionless transport parameter (K), the initial velocity vector of the particles, and the ratio of the ...
  • Impact cratering in viscous targets: Laboratory experiments 
    Greeley, Ronald; Fink, J.; Gault, Donald E.; Snyder, D. B.; Guest, John, 1938-2012; Schultz, Peter H., 1944- (Pergamon Press, 1980)
    Martian multilobed craters ("splosh" craters, rampart craters, etc.) may involve fluidization of ejecta as a result of entrained water, melted/vaporized ice, and /or aerodynamically decelerated ejecta. To determine the ...
  • Impact heat driven volatile redistribution at Occator crater on Ceres as a comparative planetary process 
    Schenk, Paul M.; Scully, J. E. C.; Buczkowski, Debra L.; Sizemore, Hanna G.; Schmidt, B.; Pieters, Carlé M.; Neesemann, A.; O'Brien, D. P.; Marchi, Simone; Williams, David A. (Planetary geologist); Nathues, A.; De Sanctis, M. Cristina; Tosi, F.; Russell, C. T. (Christopher T.); Castillo-Rogez, Julie; Raymond, Carol A. (Nature, 2020-08-10)
    Here we show using Dawn high-resolution stereo imaging and topography that Ceres' unique composition has resulted in widespread mantling by solidified water- and salt-rich mud-like impact melts with scattered endogenic ...
  • Interpreting statistics of small lunar craters 
    Schultz, Peter H., 1944-; Greeley, Ronald; Gault, Donald E. (Pergamon Press, 1977)
    Analysis of statistics of craters between 5 and 500 m reveals three major size-frequency distribution types that appear to be related to unit type.
  • Ocean resurge‑induced impact melt dynamics on the peak‑ring of the Chicxulub impact structure, Mexico 
    Schulte, Felix M.; Wittmann, Axel 1971-; Jung, Stefan; Morgan, Joanna V.; Gulick, Sean P. S.; Kring, David A. (David Allen); Grieve, Richard A. F.; Osinski, Gordon R.; Riller, Ulrich; IODP-ICDP Expedition 364 Science Party; https://orcid.org/0000-0002-3440-6282 (Springer, 2021-03-18)
    Core from Hole M0077 from IODP/ICDP Expedition 364 provides unprecedented evidence for the physical processes in effect during the interaction of impact melt with rock-debris-laden seawater, following a large meteorite ...
  • Traces of catastrophe : a handbook of shock-metamorphic effects in terrestrial meteorite impact structures 
    French, Bevan M. (Lunar and Planetary Institute, 1998)
    Emphasizes terrestrial impact structures, field geology, and particularly the recognition and petrographic study of shock-metamorphic effects in terrestrial rocks.
