  of 
  younger 
  material. 
  If 
  the

  the 
  north 
  coast 
  (in 
  West 
  Spitsbergen

   in 
  Northeast

  previously

  to 
  be 
  

   Archean, 
  are 
  found 
  upon 
  further 
  investigation 
  to 
  contain 
  

   Caledonian 
  igneous 
  masses, 
  the 
  zone 
  containing 
  Caledo- 
  

   nian 
  intrusives 
  here 
  in 
  the 
  far 
  north 
  will 
  be 
  found 
  to 
  be 
  

   exceedingly 
  wide, 
  about 
  350 
  km., 
  in 
  a 
  west-east 
  direction. 
  

   However, 
  the 
  zone 
  containing 
  corresponding 
  igneous 
  

   masses 
  in 
  districts 
  of 
  Norway 
  is 
  also 
  very 
  wide, 
  200 
  km.

  no
