Tectonic implications of Precambrian shear belts in western Greenland

Abstract

The occurrence of four Precambrian shear zones in western Greenland may point to the existence of a lithospheric plate during Proterozoic times. The large scale, ductile, transcurrent movements can be interpreted as tectonically deeper expressions of major transcurrent faults and may represent the internal distortion of a Precambrian continental block.
