The formation is partly hornfelsed in the thermal aureole of the Carn Chuinneag granite gneiss pluton: hornfelsed pelite locally preserves laminations, ripple marks, cross-bedding and possible mud cracks (Wilson and Shepherd, 1979). Andalusite and cordierite assemblages occur in the aureole."@en . "Conformably upon the Crom Psammite Formation (CMPS).
