In the present paper the author is treating the questions of the geology of the south-eastern parts of the Swedish Archaean, the relationship of its effusives, gneisses and granites. He thereby attaches his new establishments to the earlier paper published in this journal on the Archean of Western Blekinge, and widens the geological aspects to Eastern Scania and Southern Småland. Principally the genetical relations between the rocks of the area are treated in the first hand, envolving the old interesting problem on the boundary between the gneissose regions of South-Western Sweden and the granites, migmatites and metamorphic sediments of the south-eastern regions. Special attention is hereby drawn to the appearance of supra-crustal material in the horsts of Scania, which by the author is considered an equivalent to the corresponding geological features in the border terrains of the Halen sea district.
