 II. The Primitive Slate Formation. 

 B : The Schistose Group. 

 The second or schistose division of the Primitive Slate Forma- 

 tion in Norway, may be said to exist, with certainty, in two dis- 

 tinct areas, the one to the northeast and southeast of VestQord, in 

 the Nordlands, and the other to the northeast, west, southeast, and 

 south of Trondhjem. Keilhau describes the former of these re- 

 gions as " The Mica Schist districts of Tromsen and Senjen." The 

 latter region he includes in what he entitles " The Norwegian 

 portion of the central transition territory of the Scandinavian 

 Peninsula," because it appears, through transitions, to stand in 

 intimate connection with the fossiliferous Silurian strata, which 

 are developed around the northern end of Mjosen Lake. Be- 

 lieving however, with Naumann, that although the division line 

 between the two formations, may sometimes become very indis- 

 tinct, nevertheless, "on careful examination its existence will be 

 found in most cases, capable of demonstration," I have assumed, 

 with him, that the strata of the last mentioned region belongs 

 to the Schistose Group of the Primitive Slate Formation. 



The rocks of which they are composed are given in the fol- 

 lowing list, in the order of the frequency of their occurrence.
