Named in honor of Stuart Ross Taylor, one of the world’s leading geochemists, who has worked extensively on the abundances of the elements in the earth, moon and meteorites. His high-precision analyses have taught us much about the origin and evolution of the earth’s continental crust, the sources of magmas, and the origin and evolution of the moon. As an author, he has presented comprehensive overviews of lunar and planetary science. (M 29670) _ _.
