  cal, 
  with 
  the 
  Bagra 
  beds 
  sloping 
  from 
  them 
  at 
  a 
  low 
  undulating 
  dip, 
  

   a 
  thin 
  dyke 
  locally 
  occupying 
  the 
  fault. 
  It 
  is 
  at 
  the 
  edge 
  of 
  one 
  of 
  the 
  

   branches 
  of 
  the 
  complex 
  dyke 
  along 
  this 
  boundary 
  that 
  the 
  hot 
  springs 
  

   occur 
  south 
  of 
  Anhoni 
  (Unhonee) 
  . 
  The 
  feature, 
  on 
  the 
  whole, 
  suggests 
  a 
  

   rapid 
  southernly 
  thickening 
  and 
  settlement 
  of 
  the 
  deposits 
  close 
  to 
  the 
  

   edge 
  of 
  the 
  basin. 
  North 
  of 
  this 
  boundary, 
  the 
  Talchirs 
  quickly 
  

   assume 
  a 
  low 
  dip 
  and 
  are 
  even 
  horizontal 
  for 
  some 
  length. 
  At 
  a 
  mile 
  

   down 
  the 
  Kukurkhodi 
  stream, 
  to 
  west 
  of 
  it 
  at 
  a 
  bend, 
  the 
  clays 
  rest 
  

   against 
  a 
  small 
  low 
  inlier 
  of 
  metamorphies, 
  within 
  half 
  a 
  mile 
  of 
  the 
  main 
  

   boundary. 
  

  

  The 
  main 
  boundary 
  here, 
  in 
  the 
  bay 
  of 
  Anhoni, 
  the 
  Talchirs 
  being

  „ 
  the 
  ffroup 
  at 
  the 
  contact, 
  presents 
  two 
  features 
  that 
  

   Main 
  boundary 
  in 
  the 
  ° 
  r 
  x 
  

  

  Anhdni 
  region. 
  have 
  been 
  already 
  noticed 
  in 
  this 
  position 
  ; 
  namely, 
  

  

  special 
  disturbance, 
  and 
  the 
  occurrence 
  of 
  trap 
  in 
  force 
  as 
  the 
  contact- 
  

   rock 
  ; 
  and 
  both 
  are 
  difficult 
  of 
  interpretation. 
  In 
  the 
  soft 
  Talchfr 
  strata 
  

   the 
  feature 
  of 
  disturbance 
  does 
  not 
  present 
  the 
  constant 
  form 
  of 
  a 
  steep 
  

   normal 
  anticlinal, 
  as 
  seen 
  in 
  the 
  harder 
  rocks 
  of 
  the 
  upper 
  groups. 
  

   Here 
  the 
  high 
  underlie 
  is 
  sometimes 
  from, 
  sometimes 
  towards, 
  the 
  

   boundary. 
  The 
  suppositions 
  suggested 
  in 
  explanation 
  of 
  this 
  special 
  

   disturbance 
  were 
  — 
  the 
  original 
  presence 
  of 
  a 
  mass 
  of 
  metamorphic 
  rocks, 
  

   subsequently 
  removed 
  by 
  denudation, 
  or, 
  a 
  general 
  fault 
  throwing 
  down 
  

   the 
  rocks, 
  whatever 
  they 
  were, 
  on 
  the 
  north. 
  A 
  leading 
  difficulty 
  in 
  

   both 
  cases 
  is, 
  how 
  all 
  subsequent 
  denudation 
  should 
  haye 
  just 
  worked 
  up 
  

   to 
  this 
  ancient 
  line 
  of 
  disturbance, 
  leaving 
  it 
  intact 
  at 
  so 
  many 
  points. 
  

   In 
  the 
  section 
  described 
  in 
  the 
  Anjan 
  the 
  mode 
  of 
  contact 
  of 
  the 
  trap 
  is 
  

   not 
  seen. 
  In 
  the 
  Sitariva, 
  trap 
  does 
  not 
  appear 
  outside 
  the 
  boundary, 
  

   being 
  probably 
  only 
  covered 
  by 
  the 
  superficial 
  deposits. 
  There 
  was 
  

   the 
  further 
  reason 
  for 
  ignoring 
  the 
  trap 
  in 
  the 
  discussion 
  of 
  the 
  

   boundary 
  to 
  the 
  east, 
  in 
  the 
  fact 
  (to 
  be 
  shown 
  presently) 
  that 
  its 
  eruption 
  

   was 
  of 
  later 
  date 
  than 
  the 
  main 
  disturbance, 
  and 
  the 
  main 
  denudation, 
  of 
  

   the 
  sedimentary 
  rocks. 
  But 
  in 
  the 
  Anhoni 
  region 
  it 
  seems 
  impossible 
  to
