  geology 
  of 
  the 
  lower 
  narbada 
  valley. 
  

  

  district 
  north 
  and 
  east 
  of 
  that 
  now 
  depopulated 
  town. 
  In 
  the 
  south, 
  

   the 
  cretaceous 
  beds 
  are 
  cut 
  off 
  by 
  an 
  intrusion 
  of 
  basalt, 
  and 
  altered 
  sedi- 
  

   mentary 
  rocks 
  were 
  met 
  with 
  along 
  the 
  boundary 
  in 
  this 
  direction 
  

   and 
  for 
  miles 
  south 
  of 
  it. 
  The 
  beds 
  in 
  the 
  northern 
  and 
  southern 
  por- 
  

   tions 
  of 
  the 
  inlier, 
  dip 
  in 
  opposite 
  directions, 
  best 
  seen 
  in 
  tbe 
  Ankhar 
  

   river 
  at 
  Umrali 
  and 
  at 
  Vegalgaon 
  (B) 
  . 
  It 
  is 
  probable, 
  therefore, 
  that 
  Ali 
  

   stands 
  on 
  an 
  anticlinal 
  axis. 
  The 
  beds 
  here 
  (including 
  the 
  highly 
  fossili- 
  

   ferous 
  nodular-limestone 
  and 
  the 
  Lametas) 
  cannot 
  be 
  less 
  than 
  500 
  feet 
  

   in 
  thickness. 
  The 
  greater 
  portion 
  of 
  this 
  thickness 
  is 
  made 
  up 
  by 
  mas- 
  

   sive 
  conglomerates 
  at 
  the 
  base. 
  Fine-grained 
  beds 
  prevail, 
  as 
  usual, 
  

   towards 
  the 
  top. 
  

  

  The 
  Ali 
  beds 
  are 
  continued 
  westward 
  as 
  a 
  narrow 
  belt, 
  and 
  between 
  

   Utaoli 
  and 
  Phulmal 
  form 
  a 
  fringe 
  to 
  the 
  metamorphics. 
  The 
  dips 
  are 
  

   in 
  the 
  usual 
  south-east 
  direction. 
  They 
  are 
  rather 
  high 
  at 
  places, 
  as 
  at 
  

   Jharkali, 
  where 
  the 
  inclination 
  is 
  25°, 
  to 
  S.-20°-E. 
  But 
  this 
  abnormality 
  

   was 
  clearly 
  seen 
  to 
  be 
  due 
  to 
  an 
  intrusive 
  dyke. 
  The 
  junction 
  beds 
  

   between 
  the 
  igneous 
  and 
  the 
  sedimentary 
  series 
  are 
  altered 
  and 
  tinted 
  

   yellow 
  or 
  brown. 
  

  

  The 
  Kdwant 
  area. 
  — 
  The 
  inliers 
  in 
  this 
  area 
  appear 
  all 
  to 
  have 
  been 
  

   brought 
  up 
  by 
  violent 
  subterraneous 
  movements, 
  and 
  are 
  so 
  interesting 
  

   that 
  they 
  deserve 
  detailed 
  notice. 
  Leaving 
  out 
  an 
  insignificant, 
  un- 
  

   mapable 
  patch 
  covering 
  only 
  a 
  few 
  yards 
  at 
  Raisingpura, 
  there 
  are 
  

   4 
  inliers, 
  which 
  I 
  shall, 
  for 
  convenience 
  of 
  description, 
  term 
  severally 
  

   the 
  northern 
  or 
  Galeser 
  inlier, 
  the 
  middle 
  or 
  Mohan 
  inlier, 
  the 
  southern 
  

   or 
  Mongra 
  inlier, 
  and 
  the 
  western 
  or 
  Tarkachla 
  inlier. 
  

  

  1. 
  The 
  middle 
  inlier. 
  — 
  This 
  is 
  the 
  largest. 
  It 
  rises 
  as 
  a 
  ridge 
  of 
  

   sandstone 
  from 
  the 
  Deccan 
  trap 
  beds, 
  north 
  of 
  Rendi 
  (the 
  eastern 
  ex- 
  

   tremity), 
  and 
  runs 
  in 
  a 
  north-western 
  direction 
  for 
  about 
  2 
  J 
  miles. 
  

   The 
  ridge 
  then 
  curves 
  southward, 
  and 
  pursuing 
  a 
  course 
  roughly 
  parallel 
  

   with 
  the 
  strike 
  for 
  another 
  2 
  J 
  miles, 
  is 
  lost 
  amongst 
  rises 
  of 
  sandstone 
  

   cut 
  through 
  by 
  numerous 
  streamlets, 
  exposing 
  at 
  places 
  intrusive 
  sheets 
  

   and 
  dykes 
  to 
  be 
  noticed 
  hereafter. 
  

  

  The 
  sandstones 
  are 
  thickest 
  about 
  the 
  ruins 
  of 
  Mohan, 
  where 
  they
