Wilhelms D.E. (Ed.) The Geologic History of the Moon

U.S.Geological Survey Professional Paper 1348 — Washington: US Government Printing Office, 1987. — 329 p. — ISBN: 1495919854.The Moon held little interest for most scientists after its basic astronomic properties had been determined and before direct exploration appeared likely. Speculations about its internal structure, composition, and origin were only broadly constrained by cosmochemical data from meteorites and solar spectra, and by astronomic data about its size, shape, motions, and surficial properties.
