This presentation describes the relatively newly discovered phenomenon of polygonal faulting in shales, and attempts to offer a physical explanation. Polygonal fault systems are widely developed in many shale sequences around the world, some of which are hosts to prolific shale gas reserves, so understanding these faults and how they form is a pre-requisite for the exploitation of shale gas deposits
