Ronne river. Blekinge. The lime in the striped clay (Swed. ; varvig lera»), which is wide spread in the lower parts of the province, has a rather low percentage, the average being Smdinnd. The striped clay on the coast of the Sound of Kalmar from the borders reous rocks or of deposits which have plenty of lime, thanks to their mineralogical character orbybeing traversed by water rich in lime. Of calcareous rocks there are in the first place the limestones and the strongly calcareous slates, with a lime percentage of from 20—30% up to 90 °o. Even greenstones of various kinds (hyperites, gabbros, dio- rites etc.) are generally com- paratively calcareous, though rather varying in their per- centage of lime; the percen- tage of lime is said to reach ID. Fig. 4 shows the distri- bution of calcareous rocks and soil in South Sweden. To this some short notes will be given, chiefly after Lindstrom, 1898. Skdne. Throughout almost the whole province the ground is formed of a strongly calcareous moraine or marl, 2 c—30 % of lime. A northern border-line can be laid down for the lime- rich district: From the chalk region of north-eastern Skane to the west in the parishes
