dc.description.abstract | The common minor scale kink-zones of upper levels of the Furulund schists of eastern Norwegian Sulitjelma generally do not occur in conjugate pairs: usually only the member with northwest dipping axial plane is developed although at lower levels rarely both conjugate pairs and single members occur. The kink-zones fit the simple shear mechanism of development proposed by Dewey and Roberts. The upper kink-zones are characterised by a well-developed metamorphic differentiation structure resulting fron the juxtaposition of zones alternately rich in mica and quartz. In many of the kink-zones the mica-rich zones are bent by smaller scale folds unknown elsewhere in the region but which are geometrically conjugate to the minor-scale structure in which they lie. Although they clearly are later than the kink-zones it is judged that they are directly related to them. | |
