Primordial Noble Gases in "Phase Q" from the CV3 Chondrite Vigarano Studied by Closed-System Step Etching (CSSE)
Abstract
We present the first closed-system step etching experiment on the acid-resistant residue of a reduced CV3 chondrite, Vigarano. Its phase Q noble gas composition reflects a higher degree of hydrous alteration than experienced by the CV3ox chondrites.
