Relict permafrost structures (ice-wedge casts and cryoturbation structures) are present in the Gobi of southern Mongolia. Luminescence dates of sediments are presented to constrain the age of formation of permafrost structures. These data show that there was a phase of permafrost development during

β¦ Synopsis
The lithologies and structures of the Dalradian rocks of the Ardsheal Peninsula, Argyllshire are described. The structures associated with the main synformal fold (part of the Appin Syncline) are shown to be F, in age. F2 structures cross the Syncline and show progressive development towards the east. The Syncline is correlated and compared with other major F, folds in the region. This interpretation is contrasted with other interpretations of the Syncline as a thirdphase structure which can be correlated with late-phase folds in the Dalradian.
