Bonjour Jacques, Hello List, As for deformed Gibeons, most people still believe that these plastic deformations are due to impact with the Earth. Buchwald argues against this and says: "This cannot, however, be true since the distortions often occur in numerous places along the periphery and almost always, moreover, display necking and other effects of tensile and shear deformation, rather than compression from impact with the ground." Instead, he says, these deformations are due to violent atmo- spheric breakup (disruption).
