Structural basis of compressive extension and shearing mechanisms in the Carpathian flysch rocks

Joanna Pinińska
According to uniaxial compression tests, variable fracturing, i.e. intragranular, intergranular or transgranular is strictly related to mineral composition and fabric of a rock. Basing on their analysis, deformation characteristics as well as the course of acoustic emission, it is possible to assess whether the resulting defects are caused by processes of extension, shearing or both of them.
