Primitive Source Revealed in the Sudbury Impact Structure: Implications for Cratering and Metal Sources
Abstract
New U-Pb zircon geochronology places constraints on As-rich target strata incorporated into the melt sheet upon initial impact and melting. Epidote Sr isotope results yields a primitive non-radiogenic source not recognized previously.
