Conference on the Origin of the Moon

Various topics relating to lunar evolution are discussed. The Moon's ancient orbital history, geophysical and geochemical constraints favoring the capture hypothesis, the site of the lunar core, chemical and petrological constraints, dynamical constraints, and mathematical models are among the topics discussed.Co-Sponsored by Division for Planetary Sciences of the American Astronomical Society, Lunar and Planetary Institute, National Aeronautics and Space AdministrationCompiled in 1984 by Lunar and Planetary InstitutePARTIAL CONTENTS: Constraints on lunar origin: Evidence preserved in Precambrian stromatolites -- Constraints on the origin of viscoelastic bodies -- Tidal dissipation in the earth and moon from lunar laser ranging -- Two lunar global asymmetries -- The moon's orbit history and inferences on its origin -- A reappraisal of Darwin's fission hypothesis and a possible limit to the primordial angular momentum of the earth -- Numerical simulations of fission--The "problem" of iron partition between earth and moon during simultaneous formation as a double planet system -- On the origin of the moon by rotational fission -- Geochemical evidence for the formation of the moon by impact induced fission of the proto-earth -- An integrated dynamical and geochemical approach to lunar origin modelling--Lunar origin: The role of giant impacts -- Models of angular momentum input to a circumterrestrial swarm from encounters with heliocentric planetesimals -- A circumterrestrial compositional filter -- Formation of the prelunar accretion disk -- Mechanical models of close approaches and collisions of large protoplanets -- Lunar origin from impact on the earth: Is it possible
