reous rocks or of deposits 

 which have plenty of lime, 

 thanks to their mineralogical 

 character orby being traversed 

 by water rich in lime. 



Of calcareous rocks there 

 are in the first place the 

 limestones and the strongh- 

 calcareous slates, with a lime 

 percentage of from 20—30% 

 up to go%. 



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 

 10. 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. 



Skd}ie. Throughout almost the 

 whole province the ground is 

 formed of a strongly calcareous 

 moraine or marl, 2c — 30 % of 

 lime. A northern border-line 

 can be laid down for the lime- 

 rich district: l*'rom the chalk 

 region of north-eastern Skane 

 to the west in the i)arishes of 

 Akarp, Vankiva and Farstorp 

 (in the neighbourhood of Hassle- 

 holm), where it takes a bend south- 

 wards to the neigbourhood of 

 Ringsjo and thence north-west- 

 wards somewhere along the 

 Ronne river. 



lUekinge. The lime in the striped clay (Swed. varvig lcra»), which is wide spread in 

 the lower parts of the province, has a rather low percentage, the average being 5.7 ?o.

 the ])Ost-Archaean calcareous rocks (Silurian limestones, chalk
