  poraneous 
  flows. 
  The 
  beds 
  in 
  contact, 
  however, 
  both 
  above 
  and 
  below, 
  

   appear 
  to 
  have 
  been 
  altered, 
  though 
  not 
  to 
  any 
  great 
  extent 
  ; 
  and 
  the 
  

   sudden 
  and 
  repeated 
  variations 
  of 
  dip, 
  and 
  the 
  local 
  dislocations 
  just 
  men- 
  

   tioned, 
  are 
  best 
  accounted 
  for 
  by 
  regarding 
  the 
  basalts 
  as 
  intrusive, 
  the 
  

   point 
  of 
  intrusion 
  being 
  that 
  towards 
  which 
  the 
  strata 
  on 
  both 
  sides 
  are 
  

   let 
  down. 
  The 
  thinner 
  sheet 
  to 
  the 
  north 
  of 
  this 
  point 
  is 
  certainly 
  in- 
  

   trusive 
  ; 
  and 
  analogy 
  would 
  lead 
  us 
  to 
  regard 
  the 
  southern 
  apparently 
  

   sister 
  sheet 
  as 
  such 
  also, 
  though 
  somewhat 
  anomalous.

  It 
  will 
  be 
  seen 
  from 
  this 
  case 
  (and 
  several 
  more 
  will 
  be 
  noticed 
  in 
  the 
  

   following 
  pages) 
  that 
  the 
  derangements 
  caused 
  by 
  igneous 
  intrusions 
  

   are 
  only 
  local, 
  though 
  the 
  underground 
  forces 
  of 
  which 
  they 
  are 
  the 
  

   indications 
  or 
  precursors 
  affect, 
  as 
  will 
  be 
  shown, 
  very 
  wide 
  areas. 
  

  

  Passing 
  down 
  the 
  Hatni 
  over 
  a 
  mile 
  of 
  trap, 
  we 
  come 
  upon 
  an 
  inter- 
  

   esting 
  inlier 
  near 
  Behron. 
  Its 
  northern 
  boundary 
  appears 
  like 
  a 
  fault, 
  

   the 
  sandstones 
  dipping 
  away 
  from 
  the 
  trap 
  at 
  8° 
  to 
  10°, 
  to 
  S.- 
  10° 
  to 
  15°-E. 
  

   They 
  thicken 
  westward, 
  and 
  at 
  the 
  junction 
  of 
  the 
  Walpur 
  stream 
  

   with 
  the 
  Hatni 
  they 
  are 
  full 
  200 
  feet 
  in 
  thickness. 
  Intrusive 
  dolerites 
  

   and 
  basalts 
  here 
  intersect 
  and 
  tilt 
  the 
  beds 
  in 
  various 
  directions 
  and 
  at 
  

   various 
  angles. 
  At 
  the 
  eastern 
  extremity 
  the 
  sandstones 
  abut 
  against 
  a 
  

   nearly 
  straight 
  dyke-like 
  ridge 
  of 
  basalts, 
  with 
  huge 
  masses 
  of 
  yellowish, 
  

   altered, 
  calcareo-siliceous 
  rocks 
  along 
  its 
  crest. 
  Southward 
  they 
  ter- 
  

   minate 
  in 
  low 
  basaltic 
  hills 
  scattered 
  all 
  over 
  with 
  blocks 
  of 
  similar 
  rocks, 
  

   which 
  will 
  be 
  noticed 
  hereafter 
  2 
  more 
  in 
  detail. 
  

  

  The 
  inliers 
  of 
  cretaceous 
  rocks 
  which 
  dot 
  the 
  hilly 
  district 
  of 
  Dei 
  

   are 
  most 
  interesting 
  in 
  connection 
  with 
  the 
  Deccan 
  trap, 
  and 
  will 
  

   be 
  taken 
  up 
  in 
  the 
  chapter 
  devoted 
  to 
  the 
  latter. 
  At 
  Ali 
  the 
  sand- 
  

   stones 
  come 
  in 
  with 
  considerable 
  and 
  sudden 
  increase 
  in 
  thickness. 
  The 
  

   faulted 
  character 
  of 
  the 
  eastern 
  boundary 
  has 
  been 
  referred 
  to 
  in 
  a 
  pre- 
  

   vious 
  chapter 
  in 
  connection 
  with 
  the 
  granitoid 
  rocks 
  which 
  occur 
  in 
  the 
  

  

  1 
  Mr. 
  Blanford 
  also 
  considers 
  the 
  basaltic 
  sheet 
  in 
  question 
  as 
  a 
  horizontal 
  dyke. 
  The 
  

   scoriaceous 
  character 
  of 
  the 
  upper 
  basalt 
  (which 
  is 
  the 
  anomaly 
  referred 
  to 
  in 
  the 
  text) 
  

   may 
  be 
  accounted 
  for 
  by 
  the 
  thinness 
  of 
  the 
  super-incumbent 
  strata. 
  This 
  would 
  argue 
  in 
  

   favour 
  of 
  their 
  being 
  regarded 
  as 
  of 
  the 
  Deccan 
  and 
  Malwa 
  trap 
  age, 
  when 
  a 
  great 
  thickness 
  

   of 
  infra-trappean 
  beds 
  would 
  have 
  been 
  denuded 
  away.
