  ON 
  THE 
  PERMIAN 
  BOCKS 
  OP 
  THE 
  LEICESTERSHIRE 
  COAL-EIELD. 
  

  

  anticlinal, 
  the 
  Post-carboniferous 
  movements 
  took 
  place 
  along 
  old 
  lines 
  

   of 
  disturbance. 
  The 
  scarcity 
  of 
  Charnwood 
  rocks 
  he 
  thought 
  due 
  to 
  

   the 
  drift 
  having 
  been 
  from 
  the 
  south, 
  and 
  this 
  would 
  help 
  to 
  account 
  

   for 
  their 
  exceptional 
  abundance 
  at 
  Hartshorn. 
  He 
  had 
  orignally 
  

   been 
  prejudiced 
  in 
  favour 
  of 
  the 
  Permian 
  being 
  the 
  base 
  of 
  the 
  

   Trias, 
  but 
  found 
  the 
  theory 
  untenable. 
  The 
  material 
  was 
  different 
  

   from 
  that 
  of 
  the 
  Eastern 
  Permian 
  and 
  from 
  the 
  material 
  which 
  

   makes 
  up 
  the 
  basement 
  breccia 
  of 
  the 
  Keuper 
  at 
  Castle 
  Don- 
  

   ington. 
  The 
  maximum 
  angularity 
  of 
  the 
  breccia 
  in 
  the 
  southern 
  

   part 
  of 
  the 
  area 
  was 
  another 
  point 
  in 
  favour 
  of 
  its 
  derivation 
  

   from 
  a 
  southern 
  source. 
  As 
  regards 
  evidence 
  of 
  a 
  faulted 
  anti- 
  

   clinal 
  in 
  the 
  subtriassic 
  ridge, 
  the 
  shales 
  were 
  found 
  to 
  be 
  in 
  a 
  

   smashed 
  condition, 
  and 
  instead 
  of 
  coming 
  to 
  quartzites 
  below, 
  some- 
  

   thing 
  altogether 
  different 
  was 
  found 
  — 
  appearances 
  which 
  could 
  only 
  

   be 
  explained 
  on 
  the 
  supposition 
  of 
  faulting.
