The problems of the Scanian horsts comprise their genesis and age. Not only the elevations of the Gneissie-Granitic Basement, forming structural and topographic highs because of their resistance to weathering (Söderås, Kullen, Hallandsås etc.) have to be mentioned in this connection. There exists a great number of minor forms, which differ materially in composition and resistance and display some variety of character, but. obey the same deeper causal forces. These are: 1. antithetic movement of the fault blocks; 2. reverse drag and 3. transverse tectonics. Although complex in detail, is each structure the result of the interplay of these factors. — The tectonic behaviour clearly demonstrates the relation of the structures to the Saxonic movements in Scania. Their age is accordingly post-Variscian.
