Query: Comment on "Compositional and Microchemical Evidence of Piezonuclear
  Fission Reactions in Rock Specimens Subjected to Compression Tests" [Strain
  47 (Suppl. 2), 282 (2011)]   It is shown that the chemical composition data published by Carpinteri et al.
in the article "Compositional and Microchemical Evidence of Piezonuclear
Fission Reactions in Rock Specimens Subjected to Compression Tests" [Strain 47
(Suppl. 2), 282 (2011)] cannot be the result of independent measurements as
claimed by the authors. Therefore, no conclusion can be drawn from them about
compositional modifications induced in the stone by hypothetical piezonuclear
reactions taking place during catastrophic failure of the material at fracture.
