1:30 p.m. Norman M. * McCulloch M. O’Neill H. Brandon A. Magnesium Isotopes in the Earth, Moon, Mars, and Pallasite Parent Body: High-Precision Analysis of Olivine by Laser-Ablation Multi-Collector ICPMS [#1447] The Earth, Moon, Mars, and differentiated asteroids share a common Mg isotopic reservoir, implying limited variation in the proportion of refractory material contributing to the terrestrial planets.
