Abstract Palaeostress inferred from brittle mesostructures in Seymour (Marambio) Island indicates a Cenozoic to Recent origin for an extensional stress field, with only local compressional stress states. Minimum horizontal stress (σ 3 ) orientations are scattered about two main NE–SW and NW–SE modes...
