﻿JURASSIC 
  ROCKS: 
  PYANOOR 
  AREA. 
  95 
  

  

  The 
  same 
  or 
  an 
  extremely 
  similar 
  conglomerate 
  appears 
  also 
  at 
  

   Attiput 
  (Oxapet 
  of 
  map), 
  one 
  and 
  a 
  half 
  mile 
  east-north-east 
  of 
  Cavit- 
  

   pooram 
  (properly 
  Kavedupooram) 
  , 
  and 
  at 
  Kunjamuttur 
  on 
  the 
  western 
  

   boundary 
  of 
  the 
  Pyanoor 
  area. 
  

  

  From 
  the 
  perfect 
  similarity 
  of 
  mineral 
  character, 
  and 
  especially 
  from 
  

   the 
  presence 
  of 
  pebbles 
  of 
  slate, 
  I 
  incline 
  to 
  consider 
  this 
  Cavitpooram 
  

   conglomerate 
  to 
  be 
  the 
  same 
  as 
  that 
  occurring 
  at 
  the 
  base 
  of 
  the 
  Conjipud- 
  

   dy 
  section. 
  The 
  Cavitpooram 
  conglomerate 
  apparently 
  lies 
  higher 
  in 
  

   the 
  series 
  than 
  the 
  beds 
  exposed 
  in 
  the 
  Chittapuram 
  section, 
  for 
  the 
  

   latter 
  have 
  a 
  southerly 
  dip 
  and 
  the 
  former 
  occupies 
  a 
  very 
  much 
  higher 
  

   level. 
  

  

  Near 
  Pyanoor 
  a 
  very 
  coarse 
  boulder-bed 
  occurs, 
  and 
  is 
  exposed 
  in 
  

  

  . 
  • 
  several 
  wells, 
  and 
  also 
  in 
  the 
  off-flow 
  channel 
  at 
  the 
  

  

  Pyanoor 
  section. 
  

  

  north 
  end 
  of 
  the 
  great 
  tank. 
  The 
  bed 
  is 
  well 
  

   exposed 
  to 
  a 
  depth 
  of 
  12 
  to 
  15 
  feet, 
  and 
  is 
  of 
  varying 
  coarseness 
  ; 
  the 
  in- 
  

   cluded 
  fragments 
  varying 
  in 
  size 
  from 
  ordinary 
  pebbles 
  to 
  rounded 
  

   masses 
  4 
  to 
  5 
  and 
  even 
  9 
  feet 
  in 
  diameter. 
  The 
  larger 
  masses 
  are 
  all 
  

   granitic 
  or 
  syenitic 
  ; 
  the 
  largest 
  noticed 
  consisted 
  of 
  very 
  coarse 
  reddish 
  

   syenite, 
  highly 
  felspathic, 
  and 
  so 
  greatly 
  decomposed 
  as 
  to 
  be 
  easily 
  crum- 
  

   bled 
  with 
  the 
  hammer, 
  other 
  smaller 
  masses 
  so 
  much 
  so 
  as 
  to 
  fall 
  to 
  

   pieces 
  altogether 
  from 
  a 
  slight 
  kick. 
  The 
  quartzite 
  boulders 
  noticed 
  

   in 
  this 
  section 
  were 
  all 
  small. 
  

  

  In 
  a 
  well 
  section 
  between 
  Pyanoor 
  tank 
  and 
  the 
  large 
  Pagoda
