Anomalous 40Ar/39Ar Shock Ages in Mbale: Nonintuitive K and Ar Behavior, Implications for the Interpretation of Shock Ages in Shocked Meteorites
Abstract
Laser 40Ar/39Ar dates, combined with K and Ar measurements, demonstrate that K loss and Ar retention in S6 shock veins results in anomalously high ages in Mbale. This illustrates the importance of determining how specific shock effects effect K and Ar.
