Meteoritic Metal in Apollo 16 Agglutinates
Abstract
Fe-Ni-Co distribution in metal globules in agglutinates from seven Apollo 16 surface soils suggests that the metal is probably meteoritic in origin, and the excess metal in Apollo 16 soil is nonlunar. If the globules are coalescence products of nanophase superparamagnetic iron (np-Fe0), then the origin of np-Fe0 is also nonlunar. A weak negative correlation between Fe and Ni in these globules provide an intriguing possibility that they may represent a series of 'progressive metamorphism'.
