Orthoccras limestone is in faet only about 75 m., a distance that is much 

 two small for the whole of the original series of beds that should lie be- 

 tween the^e two zones. Either, therefore, we must reckon with one or 

 more dislocations by folding, or with a strong compression of the beds. 

 In fact the tectonic build of the beds that are found compressed between 

 the quartz sandstone and the first bed of Orthoccras limestone cannot be 

 determined with certainly, on account of the country there being so much 

 covered up. K. O. Bjørlykke and W M. Goldschmidt, who have both

 of the above fact arrived at different results. I refer to the accompanying 

 profiles by these authors. 



As we have seen, neither of the profiles at Tømten north of Evjeviken 

 convey complete information as to the stratigraphie position of the Holmia- 

 shale. It has merely been possible to prove with reasonable certainly 

 that they are older than the Middle Cambrian and younger than the 

 quartz sandstone. Farther south along the coast of Mjøsen, i. e. at Krokviks- 

 bugten (bay) and Vindjue-landet, we find however sections that somewhat 

 clearly show the original Lower Cambrian beds, and the lowest Middle
