Age of EET79001B and Implications for Shergottite OriginsA precise Rb-Sr age of 174+/-3 Ma was determined for EET79001B. A Sm-Nd age of 169+/-23 Ma also was determined, but the Nd isotopic systematics are disturbed. This disturbance is attributed to incomplete isotopic equilibration during petrogenesis. Additional information is contained in the original extended abstract.
