  BASIN. 
  

  

  These 
  become 
  greatly 
  erushed 
  near 
  the 
  base 
  of 
  the 
  ridge, 
  and 
  are 
  there 
  

   cut 
  by 
  a 
  thin 
  dyke, 
  the 
  end 
  of 
  a 
  very 
  strong 
  dyke 
  to 
  eastward. 
  Here 
  

   again 
  we 
  have 
  an 
  instance 
  of 
  excessive 
  local 
  contortion 
  in 
  thinner 
  and 
  

   softer 
  beds 
  underlying 
  very 
  massive 
  strata 
  of 
  the 
  same 
  series 
  : 
  at 
  half 
  

   a 
  mile 
  to 
  the 
  west 
  of 
  this 
  section, 
  the 
  upper 
  coarser 
  conglomerates 
  lap 
  

   over 
  against 
  the 
  ridge 
  ; 
  and 
  in 
  them 
  the 
  main 
  trap 
  of 
  the 
  section 
  seems 
  

   to 
  die 
  out 
  or 
  to 
  be 
  very 
  thin, 
  coming 
  in 
  again 
  in 
  force 
  in 
  the 
  Talchirs 
  

   of 
  the 
  valley 
  to 
  west. 
  The 
  section 
  in 
  the 
  figure 
  involves 
  the 
  supposition 
  

   of 
  a 
  local 
  fault 
  at 
  the 
  north 
  edge 
  of 
  the 
  main 
  dyke. 
  

  

  No 
  rock 
  of 
  the 
  sedimentary 
  series 
  is 
  exposed 
  along 
  the 
  north 
  base 
  

   _, 
  , 
  , 
  , 
  . 
  . 
  of 
  the 
  Devi 
  ridge, 
  the 
  western 
  end 
  of 
  which 
  ex- 
  

  

  The 
  Anhoni 
  region. 
  

  

  pands 
  into 
  an 
  irregular 
  mass 
  nearly 
  two 
  miles 
  

  

  wide. 
  Talchir 
  clays 
  are 
  well 
  exposed 
  at 
  the 
  southern 
  and 
  eastern 
  base 
  

  

  of 
  this 
  hill. 
  In 
  the 
  former 
  position 
  they 
  are 
  intensely 
  crushed, 
  as 
  always 
  

  

  in 
  such 
  positions, 
  at 
  right 
  angles 
  to 
  the 
  general 
  strike. 
  In 
  the 
  broad 
  

  

  spread 
  of 
  the 
  same 
  beds 
  to 
  the 
  west, 
  on 
  the 
  run 
  of 
  the 
  ridge, 
  the 
  

  

  scrata 
  are 
  flatly 
  undulating 
  ; 
  having 
  near 
  the 
  ridge 
  a 
  low 
  westerly 
  dip 
  from 
  

  

  it. 
  Anhoni 
  is 
  in 
  the 
  centre 
  of 
  this 
  area. 
  It 
  would 
  seem 
  that 
  here 
  the 
  

  

  rocks 
  were 
  protected 
  from 
  compression 
  by 
  the 
  proximity 
  of 
  the 
  hard 
  

  

  supporting 
  rock 
  ; 
  the 
  contortion 
  being 
  concentrated 
  at 
  the 
  two 
  boundaries 
  

  

  of 
  the 
  Talchir 
  outcrop, 
  one 
  on 
  the 
  north, 
  which 
  is 
  the 
  main 
  boundary 
  

  

  of 
  the 
  basin, 
  and 
  one 
  on 
  the 
  south 
  with 
  the 
  Mahadeva 
  rocks 
  (see 
  fig. 
  4) 
  . 
  

  

  Both 
  these 
  junctions 
  deserve 
  separate 
  notice. 
  

  

  All 
  along 
  the 
  junction 
  of 
  the 
  Bagra 
  group 
  with 
  the 
  Talchirs 
  here,, 
  

   for 
  at 
  least 
  eight 
  miles, 
  there 
  is 
  much 
  disturbance, 
  

  

  Inner 
  (southern) 
  bound- 
  

   ary 
  of 
  the 
  Talchirs 
  in 
  with 
  profuse 
  intrusion 
  of 
  trap. 
  The 
  eruptive 
  rock 
  

   the 
  Anhoni 
  region. 
  

  

  seems 
  to 
  have 
  come 
  up 
  along 
  the 
  northern 
  limb 
  

  

  of 
  a 
  broken 
  synclinal, 
  appearing 
  under 
  and 
  between 
  highly 
  tilted 
  beds 
  

  

  of 
  the 
  strong 
  conglomeritic 
  sandstone 
  ; 
  the 
  Talchirs 
  on 
  the 
  north 
  being 
  

  

  greatly 
  crushed. 
  At 
  a 
  bend 
  in 
  the 
  Ghogra, 
  south 
  of 
  Devi 
  hill, 
  there 
  

  

  is 
  a 
  fault 
  well 
  seen 
  at 
  this 
  boundary 
  ; 
  the

  being 
  nearly
