  Holtedahl 
  — 
  Paleozoic 
  Formations 
  of 
  

  

  gneiss-granite 
  district 
  to 
  the 
  south 
  from 
  the 
  small 
  occur- 
  

   rences 
  of 
  sedimentary 
  beds 
  to 
  the 
  north, 
  in 
  the 
  Fisherman 
  

   Peninsula 
  and 
  the 
  island 
  of 
  Kildin. 
  Contrary 
  to 
  the 
  

   opinion 
  of 
  Bamsay, 
  I 
  hold 
  that 
  these 
  sediments 
  are 
  

   younger 
  than 
  the 
  dislocation, 
  and 
  that 
  they 
  probably 
  are 
  

   contemporaneous 
  with 
  the 
  tillite-b 
  earing 
  division 
  of 
  Fin- 
  

   marken, 
  since 
  in 
  places 
  they 
  are 
  observed 
  to 
  lie 
  upon 
  the 
  

   old 
  granite 
  floor. 
  The 
  fault 
  may 
  be 
  seen 
  in 
  connection 
  

   with 
  the 
  downwarping 
  of 
  the 
  crust 
  in 
  the 
  postulated 
  

   geosyncline 
  to 
  the 
  north, 
  where 
  the 
  older 
  series 
  was 
  

   deposited 
  (see 
  fig. 
  8). 
  

  

  The 
  basal 
  rocks 
  of 
  the 
  tillite-bearing 
  division 
  of 
  Fin- 
  

   marken 
  in 
  the 
  Var 
  anger 
  district 
  are 
  mostly 
  very 
  light 
  

   colored, 
  whitish 
  grey 
  sandstones, 
  resting 
  upon 
  the 
  very 
  

   uneven, 
  yet 
  well-rounded 
  hilly 
  surface 
  of 
  the 
  old 
  granite 
  

   and 
  gneiss. 
  A 
  little 
  above 
  the 
  base 
  comes 
  the 
  local 
  tillite 
  

   of 
  Bigganjargga, 
  2 
  to 
  3 
  meters 
  thick, 
  with 
  a 
  grey 
  colored 
  

   groundmass, 
  and 
  resting 
  on 
  the 
  nicely 
  striated 
  and 
  

   polished 
  surface 
  of 
  the 
  conformably 
  underlying 
  sand- 
  

   stone. 
  Above 
  the 
  typical 
  tillite, 
  which 
  is 
  found 
  in 
  two 
  

   places 
  about 
  8 
  kilometers 
  apart, 
  are 
  observed 
  coarse, 
  only 
  

   slightly 
  bedded 
  conglomerates, 
  which 
  may 
  very 
  well 
  be 
  of 
  

   fluvio-glacial 
  origin. 
  Besides 
  the 
  facts 
  mentioned, 
  the 
  

   very 
  common 
  erosion-channels 
  also 
  tell 
  of 
  purely 
  conti- 
  

   nental 
  deposition. 
  

  

  While 
  these 
  basal 
  sandstones 
  and 
  conglomerates 
  have 
  

   a 
  very 
  restricted 
  distribution, 
  higher 
  up 
  occurs 
  a 
  more 
  

   widespread 
  zone 
  with 
  mostly 
  reddish 
  brown 
  shales 
  and 
  

   sandstones, 
  above 
  which 
  follows 
  conformably 
  the 
  reddish 
  

   brown 
  tillite 
  of 
  Mortensnes. 
  Still 
  higher 
  are 
  grey 
  and 
  

   greenish 
  shales, 
  which 
  finally 
  contain 
  sandstone 
  beds. 
  

   About 
  200 
  meters 
  above 
  the 
  tillite, 
  red 
  quartzitic 
  sand- 
  

   stones 
  are 
  the 
  dominating 
  rocks. 
  The 
  greatest 
  observed 
  

   thickness 
  of 
  this 
  younger 
  division 
  is 
  400 
  to 
  500 
  meters. 
  

   The 
  reddish 
  brown 
  tillite 
  is 
  widely 
  distributed, 
  and 
  main- 
  

   tains 
  a 
  thickness 
  of 
  about 
  10 
  meters. 
  It 
  is 
  also 
  seen 
  at 
  

   the 
  Tanaf 
  jord, 
  but 
  here 
  with 
  less 
  thickness 
  and 
  smaller 
  

   bowlders. 
  This 
  wide 
  distribution, 
  and 
  the 
  occurrence 
  

   between 
  conformably 
  lying 
  shaly 
  sediments 
  without 
  any 
  

   distinct 
  boundary 
  below 
  and 
  above, 
  are 
  seemingly 
  only 
  to 
  

   be 
  explained 
  by 
  assuming 
  a 
  deposition 
  from 
  drifting 
  ice- 
  

   bergs. 
  

  

  Where 
  the 
  continental 
  ice 
  was 
  situated 
  is 
  very 
  easily 
  

   determined 
  ; 
  first, 
  we 
  know 
  that 
  there 
  was 
  a 
  high 
  southern 
  

   land 
  at 
  this 
  time 
  (see 
  fig. 
  9), 
  and 
  secondly, 
  the 
  rock
