A theory for large-amplitude Alfvenic shocks across the external magnetic field in a collisional magnetoplasma is presented. For this purpose, we use the continuity and momentum equations for the electrons and ions, together with Amperes and Faradays laws, to derive the governing nonlinear equations for large-amplitude compressional Alfvenic waves. It is found that the latter can appear in the form of large-amplitude Alfvenic shocks that propagate with the super-Alfvenic speed.
