  THE

  VALLEY. 
  

  

  a 
  few 
  yards 
  further 
  west 
  several 
  small 
  igneous 
  intrusions 
  are 
  partially- 
  

   exposed 
  ; 
  and 
  in 
  the 
  stream, 
  almost 
  at 
  the 
  western 
  extremity 
  of 
  the 
  

   village, 
  the 
  uppermost 
  beds 
  of 
  the 
  Nimar 
  sandstone 
  (the 
  thinly 
  stratified 
  

   sandy 
  shales) 
  are 
  seen 
  to 
  lose 
  themselves 
  under 
  the 
  trap 
  with 
  an 
  un- 
  

   usually 
  high 
  dip 
  (30°) 
  in 
  the 
  north-western 
  direction.

  The 
  western 
  or 
  TarJcdchla 
  inlier. 
  — 
  This 
  inlier 
  is 
  the 
  smallest. 
  It 
  

   has 
  been 
  brought 
  up 
  by 
  faults 
  roughly 
  parallel 
  to 
  those 
  which 
  bound 
  the 
  

   sister 
  inliers. 
  Along 
  the 
  boundary 
  faults, 
  the 
  non-basic 
  igneous 
  rocks 
  

   described 
  as 
  occurring 
  near 
  Galesar 
  were 
  met 
  with, 
  but 
  in 
  patches 
  too 
  

   fragmentary 
  to 
  be 
  represented 
  with 
  any 
  pretension 
  to 
  accuracy 
  on 
  such 
  a 
  

   small 
  scale 
  map 
  as 
  that 
  which 
  accompanies 
  this 
  memoir. 
  

  

  The 
  faults 
  spoken 
  of 
  above 
  were 
  evidently 
  subsequent 
  to 
  the 
  

   Deccan 
  trap 
  age 
  ; 
  for 
  the 
  rocks 
  belonging 
  to 
  the 
  latter 
  are 
  seen 
  to 
  dip 
  

   at 
  several 
  places, 
  and 
  in 
  the 
  same 
  direction 
  as 
  the 
  subjacent 
  strata, 
  and 
  

   are 
  faulted 
  against 
  the 
  latter. 
  At 
  the 
  same 
  time, 
  however, 
  the 
  move- 
  

   ments 
  which 
  caused 
  faulting 
  could 
  not 
  have 
  taken 
  place 
  long 
  after 
  

   those 
  which 
  preceded 
  or 
  accompanied 
  the 
  eruption 
  during 
  the 
  Deccan 
  

   trap 
  times. 
  The 
  coincidence 
  of 
  the 
  disturbed 
  areas 
  with 
  those 
  of 
  vol- 
  

   canic 
  eruption, 
  as 
  the 
  Kawant 
  and 
  Dei 
  areas 
  will 
  be 
  shown 
  to 
  be 
  in 
  the 
  

   following 
  pages, 
  would 
  naturally 
  lead 
  one 
  to 
  infer 
  some 
  connection 
  between 
  

   the 
  disturbing 
  movements 
  and 
  the 
  phenomena 
  of 
  eruption. 
  Indeed, 
  the 
  

   remarkable 
  parallelism 
  of 
  the 
  fault 
  lines 
  with 
  the 
  dykes, 
  1 
  and 
  the 
  fact 
  

   that 
  in 
  several 
  cases 
  dykes 
  run 
  along 
  the 
  faults, 
  would 
  thus 
  appear 
  

   to 
  favour 
  the 
  conclusion 
  that 
  these 
  were 
  not 
  far 
  removed 
  in 
  age 
  from 
  

   each 
  other.

  Drift-wood. 
  — 
  Fossils 
  are 
  rare. 
  Fragments 
  of 
  drift-wood 
  occur, 
  like 
  

   those 
  obtained 
  from 
  the 
  Gondwana 
  sandstone, 
  about 
  Katkut. 
  Pieces 
  

   of 
  undeterminable 
  bone 
  were 
  also 
  found; 
  and 
  suspicious-looking 
  casts 
  

   (or 
  rather 
  what 
  appear 
  to 
  be 
  casts) 
  abound 
  at 
  places 
  in 
  the 
  shaly 
  and 
  

   marly 
  strata. 
  

  

  At 
  several 
  places, 
  and 
  notably 
  at 
  Raisingpura 
  and 
  Mongra,
