Bulk element compositions of meteorites: A guide for interpreting remote-sensing geochemical measurements of planets and asteroids
Larry R. Nittler,Timothy J. McCoy,Pamela Elizabeth Clark,M. E. Murphy,Jacob I. Trombka,Eugene Jarosewich +5 more
TL;DR: A large database of bulk meteorite elemental abundances, compiled to aid in the interpretation of elemental abundance data determined by remote-sensing instrumentation on planetary missions, is reported in this article.
Journal ArticleDOI
Anatomy of a Partially Differentiated Asteroid: A “NEAR”-Sighted View of Acapulcoites and Lodranites
Timothy J. McCoy,Timothy J. McCoy,Larry R. Nittler,Larry R. Nittler,Thomas H. Burbine,Thomas H. Burbine,Jacob I. Trombka,Jacob I. Trombka,Pamela Elizabeth Clark,Pamela Elizabeth Clark,M. E. Murphy,M. E. Murphy +11 more
TL;DR: In this paper, the authors outline the features of a partially differentiated asteroid using the acapulcoite and lodranite meteorites as a guide, including chondritic rocks largely unaltered by melting, residues of partial melts, and basaltic and Fe,Ni-FeS rocks crystallized from the partial melts.
Journal ArticleDOI
