“…Today, both rotational (Prior, 1987;Chan & Crespi, 1999;Ikeda et al, 2002) and non-rotational (Fyson, 1980;Johnson, 1990;Aerden, 1995) behaviours have been documented in nature. The observed geometries of inclusion trails have been explained, for instance, by flexural flow folding (Visser & Mancktelow, 1992), coaxial deformation associated with passive folding (Ramsay, 1962;Stallard & Hickey, 2001;Timms, 2003), or deformation partitioning of bulk non-coaxial deformation into pure and simple shear components (Bell, 1981;Lister & Williams, 1983).…”
