﻿JURASSIC 
  ROCKS

  PYANOOR 
  AREA.

  Two 
  important 
  outliers 
  occur 
  to 
  the 
  west 
  of 
  this 
  area, 
  the 
  

   along 
  the 
  boundary 
  of 
  the 
  Naggery 
  river 
  

   alluvium 
  at 
  its 
  junction 
  with 
  the 
  Trittany 
  

   river 
  alluvium, 
  the 
  other 
  a 
  little 
  further 
  

   south 
  along 
  the 
  boundary 
  of 
  the 
  metamor- 
  

   phic 
  rocks. 
  

  

  The 
  formations 
  occurring 
  in 
  the 
  Pyanoor 
  

   area 
  all 
  belong 
  to 
  the 
  Sripermatoor 
  group, 
  

   and 
  form 
  a 
  series 
  of 
  friable 
  sandstones, 
  sandy 
  

   shales, 
  pebble 
  and 
  boulder-beds. 
  Hardly 
  any 
  

   sections 
  are 
  available 
  but 
  such 
  as 
  are 
  afforded 
  

   by 
  wells, 
  and 
  as 
  these 
  are 
  almost 
  invariably 
  

   lined 
  with 
  walls, 
  the 
  information 
  obtainable 
  

   is 
  very 
  limited, 
  and 
  it 
  is 
  impossible 
  to 
  cor- 
  

   relate 
  the 
  various 
  formations 
  of 
  different 
  

   parts 
  of 
  the 
  area 
  with 
  any 
  degree 
  of 
  cer- 
  

   tainty. 
  

  

  The 
  general 
  dip 
  of 
  the 
  whole 
  series 
  is 
  

   easterly, 
  at 
  varying 
  low 
  angles, 
  but 
  local 
  ex- 
  

   ceptions 
  to 
  this 
  general 
  dip 
  were 
  met 
  with 
  in 
  

   several 
  cases. 
  

  

  one 
  

  

  Chittapuram 
  

   section. 
  

  

  The 
  most 
  important 
  section 
  in 
  this 
  part 
  of 
  

   the 
  country 
  occurs 
  in 
  the 
  small 
  

   outlier 
  at 
  Chittapuram 
  on 
  the 
  

   banks 
  of 
  the 
  Naggery 
  river. 
  The 
  section 
  

   occurs 
  in 
  the 
  south 
  bank 
  of 
  the 
  river, 
  which 
  

   forms 
  a 
  low 
  cliff 
  about 
  14 
  to 
  15 
  feet 
  hio-h 
  

   and 
  about 
  one 
  quarter 
  of 
  a 
  mile 
  long- 
  

   (Fig.
