TL;DR: The early views of the Moon manifested in mythology and art throughout the world were primarily tied to lunar and terrestrial cycles and the relationships between the Sun and the Moon as mentioned in this paper, and many of these early views were associated with the violent or catastrophic events in which the Moon was expunged from the Earth.
Journal ArticleDOI
Oxygen fugacity and geochemical variations in the martian basalts: implications for martian basalt petrogenesis and the oxidation state of the upper mantle of Mars
TL;DR: The oxygen fugacity of the Dar al Gani 476 martian basalt is determined to be quartz-fayalite-magnetite (QFM) −2.3 ± 0.4 through analysis of olivine, low-Ca pyroxene, and Cr-spinel as discussed by the authors.
Journal ArticleDOI
Constraints on Martian differentiation processes from RbSr and SmNd isotopic analyses of the basaltic shergottite QUE 94201
TL;DR: In this article, isotope dilution data of the shergottite meteorite QUE 94201 has been used to identify a leachable crustal component in the meteorite, which can affect the isochrons by selectively altering the isotopic systematics of the leachates and some of the mineral fractions.
Journal ArticleDOI
A petrogenetic model for the origin and compositional variation of the martian basaltic meteorites
Lars E. Borg,David S. Draper +1 more
TL;DR: The major element, trace element, and isotopic compositional ranges of the martian basaltic meteorite source regions have been modeled assuming that planetary differentiation resulted from crystallization of a magma ocean as mentioned in this paper.
Journal ArticleDOI
Chronological evidence that the Moon is either young or did not have a global magma ocean
TL;DR: The age of crystallization of FAN 60025 is reported to be 4,360 ± 3 million years, an extraordinarily young age that requires that either the Moon solidified significantly later than most previous estimates or the long-held assumption that FANs are flotation cumulates of a primordial magma ocean is incorrect.
