  Several 
  small 
  and 
  barren 
  valleys 
  run 
  iuto 
  the 
  higher 
  ground 
  in 
  an 
  

   easterly 
  and 
  south-easterly 
  direction, 
  but 
  their 
  sides 
  and 
  bottoms 
  are 
  

   too 
  smooth 
  and 
  too 
  much 
  obscured 
  with 
  lateritic 
  gravel 
  debris 
  to 
  afford 
  

   instructive 
  sections. 
  About 
  a 
  mile 
  south 
  of 
  the 
  Roman 
  Catholic 
  

   Church 
  at 
  Keesary, 
  these 
  beds, 
  upon 
  which 
  the 
  village 
  stands, 
  are 
  

   covered 
  up 
  by 
  quartzite 
  gravels 
  and 
  disappear. 
  The 
  beds 
  occurring 
  at 
  the 
  

   second 
  and 
  third 
  outlying 
  sections 
  {i. 
  e., 
  those 
  at 
  Panjur 
  and 
  Coopoor), 
  

   though 
  but 
  little 
  like 
  those 
  at 
  the 
  northern 
  road 
  of 
  the 
  Sripermatoor 
  area, 
  

   have 
  a 
  very 
  considerable 
  resemblance 
  to 
  those 
  seen 
  in 
  the 
  Vautum- 
  

   baucum 
  section 
  in 
  the 
  south 
  Sripermatoor 
  area, 
  and, 
  like, 
  the 
  latter, 
  

   apparently 
  overlie 
  the 
  plant 
  shales. 
  

  

  The 
  strata 
  met 
  with 
  at 
  Panjur* 
  have 
  been 
  cut 
  across 
  the 
  bedding 
  

  

  at 
  right 
  angles 
  to 
  the 
  prevailing 
  dip, 
  which 
  is 
  

   Panjur 
  sections.

  easterly, 
  at 
  an 
  angle 
  of 
  from 
  5° 
  to

  . 
  Extensive 
  

  

  pluvial 
  erosion 
  has 
  helped 
  very 
  greatly 
  to 
  improve 
  the 
  section 
  since 
  its 
  

  

  first 
  being 
  cut.

  The 
  village 
  of 
  Panjur, 
  not 
  marked 
  on 
  the 
  map, 
  lies 
  on 
  the 
  north 
  side 
  of 
  the 
  

   great 
  Chumbrumbaucum 
  tank 
  just 
  west 
  of 
  the 
  large 
  feeding 
  channel 
  which 
  brings 
  down 
  the 
  

   water 
  of 
  the 
  Ciium 
  river. 
  The 
  section 
  was 
  formed 
  by 
  the 
  cutting 
  through 
  a 
  ridge 
  of 
  high 
  

   ground 
  capped 
  with 
  laterite. 
  The 
  cutting 
  extends 
  from 
  the 
  bridge, 
  by 
  which 
  the 
  Madras- 
  

   Arcot 
  road 
  crosses 
  the 
  channel, 
  down 
  to 
  the 
  village.
