  against 
  and 
  upon 
  which, 
  on 
  the 
  south, 
  the 
  Bagra 
  beds 
  rest 
  along 
  an 
  

   irregular 
  line; 
  but 
  from 
  Sali 
  to 
  Lokartalai 
  the 
  sandstone 
  series 
  forms 
  

   the 
  scarp, 
  the 
  crystallines 
  being 
  only 
  obscurely 
  seen 
  at 
  the 
  very 
  base. 
  

   None 
  of 
  this 
  western 
  portion 
  has 
  yet 
  been 
  worked 
  in 
  detail 
  ; 
  but 
  at 
  the 
  

   few 
  points 
  examined 
  there 
  is 
  again 
  found 
  the 
  structure 
  that 
  has 
  been 
  so 
  

   repeatedly 
  noticed 
  at 
  the 
  boundary. 
  In 
  the 
  Sali 
  glen, 
  the 
  strata 
  for 
  

   some 
  distance 
  from 
  the 
  boundary 
  have 
  a 
  low 
  dip 
  towards 
  it, 
  increasing 
  

   to 
  20° 
  near 
  it, 
  terminating 
  in 
  a 
  steep 
  face, 
  not 
  a 
  dip, 
  of 
  70°, 
  very 
  like 
  a 
  

   fault-surface. 
  Close 
  in 
  front 
  of 
  this, 
  ribs 
  of 
  metamorphic 
  limestone 
  

   and 
  hornstone 
  weather 
  out 
  through 
  trap. 
  Whether 
  the 
  trap 
  occurs 
  as 
  

   dykes 
  or 
  as 
  overflow 
  was 
  not 
  determined. 
  

  

  Five 
  miles 
  to 
  the 
  west 
  of 
  Sali, 
  along 
  the 
  base 
  of 
  the 
  scarp 
  of 
  the 
  

  

  ■kt 
  i.x- 
  v

  Moran 
  hills, 
  east 
  and 
  south 
  of 
  Jondal, 
  the 
  sand- 
  

  

  North 
  base 
  of 
  Moran 
  ' 
  

  

  hllls 
  - 
  stone 
  and 
  clay 
  conglomerates 
  have 
  a 
  moderate 
  dip 
  

  

  to 
  southwards 
  ; 
  but 
  immediately 
  at 
  the 
  boundary 
  they 
  have 
  a 
  crushed 
  dip 
  

   of 
  70° 
  to 
  northwards 
  ; 
  and 
  here, 
  too, 
  one 
  finds 
  local 
  outcrops 
  of 
  gneiss 
  where 
  

   the 
  trap 
  has 
  been 
  removed, 
  close 
  to 
  the 
  base 
  of 
  the 
  scarp. 
  Again, 
  near 
  

   Dopalwara, 
  the 
  fine 
  sandstones 
  extensively 
  quarried 
  at 
  the 
  base 
  of 
  the 
  scarp 
  

   have 
  a 
  moderate 
  northerly 
  dip 
  towards 
  the 
  trap 
  in 
  the 
  lower 
  ground. 
  

  

  It 
  would 
  simplify 
  matters 
  very 
  much 
  to 
  attribute 
  the 
  special 
  crush- 
  

   ing 
  along 
  this 
  boundary 
  of 
  the 
  Moran 
  hills 
  to 
  

  

  Indications 
  from 
  the 
  

  

  boundary 
  in 
  the 
  western 
  post-trappean 
  disturbance 
  — 
  at 
  a 
  steep 
  contact 
  of 
  

  

  region. 
  

  

  trap 
  with 
  a 
  denuded 
  edge 
  of 
  the 
  sedimentaries, 
  as 
  

   in 
  the 
  case 
  of 
  the 
  Anhoni 
  area. 
  This 
  would, 
  of 
  course, 
  leave 
  the 
  question 
  

   of 
  the 
  original 
  extension 
  of 
  the 
  sedimentaries 
  quite 
  untouched 
  ; 
  giving 
  

   rather 
  a 
  presumption 
  in 
  favor 
  of 
  their 
  spread 
  over 
  the 
  area 
  of 
  the 
  present 
  

   Narbada 
  valley. 
  Or, 
  if 
  we 
  attribute 
  the 
  present 
  features 
  of 
  the 
  boundary 
  

   to 
  pre-trappean 
  faulting 
  along 
  this 
  line, 
  and 
  take 
  the 
  form 
  of 
  the 
  con- 
  

   tortion 
  as 
  indicating 
  a 
  downthrow 
  on 
  the 
  north, 
  we 
  might 
  also 
  infer 
  the 
  

   former 
  indefinite 
  extension 
  of 
  the 
  deposits 
  and 
  their 
  present 
  existence 
  

   beneath 
  the 
  valley. 
  The 
  remaining 
  supposition 
  — 
  of 
  an 
  original 
  upland
