  nature 
  of 
  the 
  bowlders 
  of 
  the 
  different 
  conglomerates 
  is 
  

   to 
  a 
  large 
  degree 
  like 
  that 
  of 
  the 
  pre-Cambrian 
  ones 
  now 
  

   exposed 
  in 
  this 
  district. 
  We 
  also 
  find 
  in 
  the 
  different 
  

   conglomerates 
  an 
  abundance 
  of 
  sedimentary 
  rocks, 
  

   especially 
  quartzitic 
  sandstone, 
  and 
  furthermore, 
  very 
  

   commonly 
  there 
  are 
  dolomitic 
  rocks 
  with 
  the 
  characters 
  

   of 
  the 
  older 
  series, 
  and 
  with 
  cherts, 
  oolites, 
  and 
  stroma-

  Above, 
  hypothetic 
  section 
  through 
  the 
  inner 
  end 
  of 
  the 
  Varan- 
  

   gerfjord, 
  showing 
  the 
  geologic 
  structure 
  after 
  the 
  fault 
  had 
  appeared. 
  

   Below, 
  the 
  assumed 
  conditions 
  at 
  the 
  time 
  of 
  the 
  deposition 
  of 
  the 
  reddish 
  

   brown 
  tillite. 
  

  

  tolites. 
  These 
  sedimentary 
  rocks 
  had 
  their 
  home 
  above 
  

   the 
  pre-Cambrian 
  to 
  the 
  south, 
  where 
  they 
  are 
  now 
  totally 
  

   removed. 
  

  

  In 
  western 
  Finmarken, 
  in 
  the 
  Bossekop 
  series, 
  occurs 
  

   a 
  reddish 
  brown 
  rock 
  with 
  all 
  the 
  characters 
  of 
  the 
  Mor- 
  

   tensnes 
  tillite. 
  It 
  is 
  found 
  as 
  a 
  zone 
  in 
  a 
  sequence 
  of 
  

   light-colored 
  quartzitic 
  sandstones 
  with 
  minor 
  intercala- 
  

   tions 
  of 
  brown 
  shales, 
  nearly 
  200 
  meters 
  thick. 
  As 
  in 
  

   the 
  Mortensnes 
  tillite, 
  here 
  in 
  the 
  west 
  also 
  are 
  found 
  

   bowlders 
  with 
  distinct 
  glacial 
  striae 
  (fig. 
  10). 
  These 
  

   stria? 
  in 
  some 
  bowlders 
  are 
  seen 
  to 
  have 
  been 
  deformed 
  by 
  

   later 
  crustal 
  movements, 
  those 
  of 
  the 
  Caledonian 
  moun- 
  

   tain-making.
