  POOTE

  GEOLOGY 
  OF 
  MADUAS. 
  

  

  section 
  is 
  of 
  very 
  trifling 
  importance 
  except 
  as 
  a 
  proof 
  of 
  the 
  presence 
  

   of 
  the 
  Rajmahal 
  beds 
  below 
  the 
  lateritic 
  gravels 
  on 
  this 
  spot. 
  The 
  

   section 
  is 
  exposed 
  in 
  a 
  small 
  rain 
  gully 
  falling 
  from 
  the 
  south 
  into 
  

   the 
  small 
  oblong 
  tank 
  east 
  of 
  the 
  village. 
  White 
  shales 
  are 
  exposed 
  to 
  a 
  

   depth 
  of 
  about 
  2| 
  feet 
  for 
  a 
  distance 
  of 
  three 
  or 
  four 
  yards 
  below 
  a 
  thin 
  

   capping 
  of 
  lateritic 
  gravel. 
  No 
  traces 
  even 
  of 
  fossils 
  were 
  discovered 
  

   after 
  careful 
  search 
  in 
  these 
  Perumalpett 
  shales, 
  but 
  in 
  their 
  mineral 
  

   character 
  they 
  are 
  extremely 
  like 
  the 
  Sripermatoor 
  shales. 
  

  

  The 
  small 
  outlier 
  of 
  gritty 
  sandstones 
  south 
  of 
  Adigatur, 
  three 
  and 
  a 
  

  

  half 
  miles 
  north-north-east 
  of 
  Settorei 
  section, 
  is 
  

   Adigatur 
  section. 
  . 
  . 
  

  

  so 
  completely 
  isolated 
  from 
  the 
  other 
  outliers 
  both 
  

  

  at 
  Settorei 
  and 
  Coopoor, 
  that 
  it 
  is 
  not 
  easy 
  to 
  know 
  to 
  which 
  series 
  to 
  

  

  assign 
  it. 
  This 
  coarse 
  gritty 
  sandstone, 
  which 
  is 
  apparently 
  unfossilife- 
  

  

  rous, 
  shows 
  locally 
  much 
  false 
  bedding, 
  and 
  in 
  one 
  or 
  two 
  places 
  a 
  

  

  largely 
  concretionary 
  structure. 
  Small 
  portions 
  also 
  are 
  somewhat 
  calci- 
  

  

  ferous. 
  No 
  other 
  formations 
  are 
  here 
  seen 
  but 
  this 
  coarse, 
  friable 
  grit, 
  

  

  which 
  is 
  only 
  exposed 
  on 
  the 
  north 
  side 
  of 
  a 
  low 
  bluff 
  rising 
  over 
  the 
  

  

  alluvium 
  of 
  the 
  f 
  Old 
  Palar' 
  valley. 
  The 
  high 
  ground 
  south 
  of 
  the 
  

  

  bluff 
  is 
  covered 
  with 
  lateritic 
  gravel. 
  

  

  South 
  of 
  Settorei 
  outlier, 
  are 
  some 
  traces 
  of 
  a 
  boulder-bed 
  like 
  

   those 
  in 
  the 
  Pyanoor 
  area, 
  which 
  may 
  be 
  regarded 
  as 
  a 
  connecting 
  link 
  

   between 
  the 
  Sripermatoor 
  area 
  and 
  the 
  outliers 
  in 
  the 
  neighbourhood 
  

   of 
  Conjeveram. 
  On 
  the 
  high 
  ground 
  between 
  

   Boulders 
  a 
  JP 
  Aryapaucum 
  and 
  Kanontangul, 
  'numerous 
  well- 
  

  

  rounded 
  blocks 
  of 
  granite 
  and 
  gneiss 
  occur 
  scattered 
  

   over 
  the 
  surface 
  of 
  the 
  quartzite 
  shingle. 
  This 
  quartzite 
  shingle 
  is 
  

   of 
  questionable 
  age, 
  and 
  belongs 
  to 
  the 
  gravels 
  I 
  have 
  named 
  the 
  

   Conieveram 
  gravels, 
  which 
  were 
  most 
  likely 
  formed 
  of 
  the 
  materials 
  

   of 
  destroyed 
  conglomerate 
  beds 
  of 
  the 
  Rajmahal 
  series. 
  The 
  mineral 
  

   character 
  of 
  the 
  boulders 
  strongly 
  resembles 
  the 
  boulders 
  cropping 
  up 
  

   through 
  the 
  lateritic 
  shingle 
  at 
  Catramatoor 
  and 
  Moshoor, 
  suggesting
