﻿BOUNDARIES.

  The 
  position 
  of 
  the 
  boundary 
  here 
  lies 
  more 
  to 
  the 
  south 
  than 
  the 
  

   run 
  of 
  the 
  boundary 
  on 
  the 
  upland, 
  in 
  the 
  region 
  of 
  the 
  Kanhan 
  and 
  

   the 
  Pench 
  ; 
  so 
  that 
  any 
  great 
  fault 
  there 
  would 
  strike 
  into 
  the 
  basin 
  to 
  

   the 
  west. 
  The 
  junction 
  on 
  the 
  upland 
  is 
  much 
  concealed 
  by 
  trap 
  ; 
  but 
  

   when 
  seen, 
  as 
  on 
  the 
  Kanhan 
  south 
  of 
  Nandora, 
  the 
  Talchirs 
  are 
  in 
  force 
  

   along 
  it. 
  Both 
  here 
  and 
  in 
  the 
  Tawa 
  valley 
  there 
  is 
  often 
  much 
  crush- 
  

   ing 
  at 
  the 
  boundary 
  ; 
  and 
  within 
  the 
  basin, 
  near 
  and 
  within 
  some 
  miles 
  

   of 
  the 
  boundary, 
  and 
  parallel 
  to 
  it, 
  there 
  are 
  many 
  small 
  and 
  large 
  ribs 
  

   of 
  pseudomorphic 
  vein-quartz. 
  This 
  is 
  identical 
  with 
  the 
  rock 
  so 
  often 
  

   assumed 
  as 
  ''fault-rock-'; 
  but 
  it 
  is 
  remarkable 
  here 
  that 
  this 
  rock 
  is 
  not 
  

   found 
  at 
  the 
  contact, 
  even 
  where 
  most 
  steep 
  ; 
  nor 
  is 
  there 
  any 
  sign 
  of 
  it 
  

   in 
  the 
  well-exposed 
  fault 
  throwing 
  up 
  the 
  coal 
  in 
  the 
  Pench 
  river 
  near 
  

   Chenda. 
  And 
  at 
  these 
  ribs 
  themselves 
  there 
  is 
  no 
  sign 
  of 
  special 
  contor- 
  

   tion 
  or 
  shifting, 
  although 
  the 
  contiguous 
  rock 
  is 
  often 
  splintered 
  and 
  

   ramified 
  with 
  quartz. 
  

  

  The 
  whole 
  structure 
  of 
  the 
  rock-basin 
  suggests 
  that 
  there 
  was 
  

   a 
  general 
  rise 
  of 
  the 
  ground 
  to 
  the 
  south, 
  probably 
  at 
  the 
  time 
  of 
  the 
  

   general 
  disturbance 
  of 
  the 
  strata; 
  but 
  there 
  is 
  as 
  yet 
  no 
  sufficient 
  

   evidence 
  that 
  this 
  was 
  attended 
  by 
  general 
  faulting 
  at 
  the 
  boundary.
