39Ar -40Ar Ages of Two Nakhlites, MIL 03346 and Y 000593: A Detailed Analysis
Abstract
MIL 03346 and Y 000593 were analyzed for 39Ar-40Ar ages. The both whole rock and mineral separates of plagioclase (plus mesotasis) Ar-Ar ages are older than other radiometric ages. It seems that most excess 40Ar is located in the plagioclase.
