  place 
  in 
  the 
  Trondhjem 
  district 
  in 
  central 
  Norway 
  in 
  

   early 
  Cambro-Ordovician 
  time, 
  and 
  these 
  may 
  very 
  well 
  

   be 
  correlated 
  with 
  those 
  of 
  the 
  Raipas. 
  

  

  The 
  land 
  barrier 
  above 
  pointed 
  ont 
  appears 
  to 
  have 
  

   continued 
  into 
  Black 
  River 
  time, 
  as 
  is 
  indicated 
  by 
  the 
  

   fossils 
  of 
  Bear 
  Island, 
  bnt 
  it 
  may 
  have 
  had 
  a 
  somewhat 
  

   different 
  situation. 
  While 
  the 
  Bear 
  Island 
  fauna 
  is 
  of 
  a 
  

   decidedly 
  American 
  character, 
  it 
  is 
  a 
  well 
  known 
  fact 
  that 
  

   the 
  Middle 
  Ordovician 
  faunas 
  of 
  the 
  southern 
  Scandina- 
  

   vian 
  Baltic 
  region 
  (except 
  the 
  graptolites 
  and 
  bryozoans) 
  

   do 
  not 
  show 
  American 
  relations 
  at 
  all. 
  The 
  same 
  may 
  be 
  

   said 
  of 
  a 
  northern 
  fauna 
  of 
  about 
  the 
  same 
  or 
  probably 
  of 
  

   a 
  somewhat 
  younger 
  age 
  than 
  the 
  one 
  from 
  Bear 
  Island, 
  

   found 
  by 
  Nansen 
  at 
  the 
  south 
  side 
  of 
  Yugor 
  Strait 
  (Nova 
  

   Zembla) 
  and 
  described 
  by 
  Kiaer.

  While 
  in 
  my 
  opin- 
  

   ion 
  the 
  stromatolite-bearing 
  dolomite 
  of 
  the 
  Kanin 
  Penin- 
  

   sula 
  is 
  indicative 
  of 
  the 
  earliest 
  American 
  Ordovician 
  

   facies, 
  yet 
  that 
  of 
  Yugor 
  Strait 
  shows 
  that 
  this 
  Arctic 
  

   Russian 
  district 
  belongs 
  to 
  the 
  Scandinavian 
  Baltic 
  

   faunal 
  province 
  of 
  Middle 
  Ordovician 
  time. 
  

  

  Younger, 
  Tillite-bearing 
  Sandstone 
  of 
  Finmarken. 
  

  

  Unconformably 
  above 
  the 
  dolomite-bearing 
  division 
  

   comes 
  a 
  younger 
  series, 
  without 
  dolomites 
  but 
  with 
  

   tillit.es. 
  The 
  unconformity 
  between 
  them 
  is 
  not 
  very 
  

   strongly 
  marked 
  in 
  eastern 
  Finmarken, 
  though 
  in 
  places 
  

   it 
  is 
  readily 
  seen, 
  e. 
  g., 
  at 
  the 
  inner 
  end 
  of 
  the 
  Varanger- 
  

   fjord. 
  In 
  western 
  Finmarken 
  it 
  is 
  much 
  more 
  marked, 
  

   indicating 
  that 
  the 
  Raipas 
  series 
  was 
  folded 
  before 
  the 
  

   tillite-bearing 
  division 
  (the 
  Bossekop 
  series) 
  was 
  depos- 
  

   ited. 
  The 
  presence 
  of 
  this 
  folding 
  was 
  one 
  of 
  the 
  reasons 
  

   why, 
  in 
  my 
  preliminary 
  paper, 
  22 
  written 
  when 
  I 
  had 
  seen 
  

   only 
  this 
  western 
  part 
  of 
  Finmarken, 
  I 
  was 
  led 
  to 
  con- 
  

   clude 
  that 
  the 
  Raipas 
  formation 
  was 
  of 
  young 
  pre-Cam- 
  

   brian 
  age, 
  since 
  such 
  a 
  pre-Caledonian 
  folding 
  was 
  not 
  

   previously 
  known 
  in 
  the 
  Cambro- 
  Silurian 
  of 
  the 
  Scan- 
  

   dinavian 
  peninsula. 
  

  

  Preceding 
  the 
  deposition 
  of 
  the 
  tillite-bearing 
  division, 
  

   we 
  have 
  in 
  eastern 
  Finmarken 
  the 
  origin 
  of 
  a 
  big 
  fault. 
  

   This 
  is 
  especially 
  distinct 
  at 
  the 
  inner 
  end 
  of 
  the 
  Varan- 
  

   gerfjord, 
  and 
  it 
  is 
  without 
  doubt 
  continued 
  along 
  the 
  

   north 
  coast 
  of 
  the 
  Kola 
  Peninsula, 
  where 
  Ramsay 
  long 
  

   ago 
  assumed 
  a 
  fault 
  line, 
  dividing
