Abstract
Summary: Schemes of Scottish Caledonian metamorphic zonation involving the Thermal Anticline have traditionally been used for reconstructing movement on the Great Glen Fault. Interpretation of the highland zonal pattern in terms of inverted zones severally parallel to the Moine Thrust and to the Highland Border Fault, representing perturbation of isotherms by under-thrusting, can be fitted to either sinistral or dextral models of transcurrent motion.
