3. 2. A study of shock-metamorphic features in zircon from the Siljan impact structure, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Josefin Martell; [2016]
   Keywords : Zircon; impacts; shock metamorphism; shock metamorphic features; planar deformation features; Siljan impact structure; Earth and Environmental Sciences;
