  GEOLOGY 
  OF 
  KATHIAWAR 
  PENINSULA 
  IN 
  GUZERAT. 
  

  

  The 
  deposition 
  of 
  the 
  conglomeratic 
  rock 
  is 
  very 
  irregular, 
  at 
  times 
  

   presenting 
  a 
  tilted 
  appearance, 
  the 
  effect 
  of 
  false 
  bedding. 
  I 
  may 
  here 
  

   remark 
  that 
  the 
  observations 
  by 
  several 
  writers, 
  of 
  high 
  dip 
  and 
  distur- 
  

   bance 
  of 
  the 
  Piram 
  beds, 
  are 
  a 
  misinterpretation 
  of 
  the 
  oblique 
  and 
  

   irregular 
  nature 
  of 
  their 
  deposition. 
  As 
  already 
  stated, 
  the 
  strata 
  are, 
  

   on 
  the 
  whole, 
  about 
  horizontal. 
  The 
  beds 
  vary 
  in 
  thickness 
  from 
  two 
  

   feet 
  downwards., 
  and 
  occasionally 
  thin 
  out 
  altogether. 
  

  

  Some 
  of 
  the 
  intermediate, 
  or 
  partition, 
  beds 
  of 
  sandstone 
  are 
  but 
  

   slightly 
  coherent, 
  being 
  a 
  grey 
  finely 
  micaceous 
  laminated 
  sand 
  (hence 
  

   Captain 
  Ethersey's 
  term 
  ' 
  recent 
  sandstone 
  ' 
  ) 
  ; 
  others 
  are 
  more 
  impure, 
  

   muddy, 
  and 
  silty, 
  — 
  a 
  sandy 
  mud 
  deposit. 
  A 
  few 
  are 
  shaly. 
  

  

  Nearly 
  all 
  the 
  conglomeratic 
  beds 
  are, 
  more 
  or 
  less, 
  ossiferous; 
  the 
  

  

  higher 
  ones 
  less 
  so 
  : 
  but 
  it 
  is 
  one 
  of 
  the 
  lower, 
  and 
  

   Position 
  of 
  fossil 
  bed. 
  . 
  

  

  perhaps 
  rather 
  more 
  ferruginous, 
  beds 
  that 
  has 
  

  

  proved 
  so 
  prolific 
  in 
  fossil 
  wood 
  and 
  bones. 
  This 
  bed 
  is 
  situated 
  con- 
  

   siderably 
  below 
  the 
  level 
  of 
  high 
  water 
  ; 
  and 
  for 
  more 
  than 
  half 
  the 
  

   year, 
  is 
  obscured 
  by 
  a 
  thick 
  covering 
  of 
  mud. 
  During 
  the 
  months 
  of 
  

   April, 
  May, 
  and 
  June, 
  the 
  fossil 
  ground, 
  or 
  the 
  south-eastern 
  end 
  of 
  the 
  

   reef, 
  becomes 
  scoured 
  and 
  free 
  from 
  mud 
  ; 
  when 
  the 
  village 
  men 
  search 
  

   for 
  specimens 
  at 
  low 
  tide, 
  finding 
  them 
  washed 
  up 
  by 
  the 
  surf. 
  The 
  

   principal 
  fossil 
  bed 
  cannot, 
  therefore, 
  be 
  included 
  in 
  the 
  section 
  of 
  strata 
  

   quoted 
  from 
  Captain 
  Ethersey's 
  paper 
  ; 
  as 
  there 
  he 
  mentions 
  that 
  the 
  

   lowest 
  bed 
  of 
  it 
  is 
  washed 
  by 
  the 
  high-spring 
  tides. 
  A 
  considerable 
  

   amount 
  of 
  uncertainty 
  has 
  hitherto 
  existed 
  regarding 
  the 
  proper 
  position 
  

   of 
  the 
  principal 
  fossil-bearing 
  band, 
  but 
  my 
  observations 
  show 
  that 
  it 
  is 
  

   as 
  above 
  stated. 
  

  

  The 
  bones 
  I 
  saw 
  in 
  situ 
  and 
  otherwise, 
  in 
  my 
  search 
  over 
  the 
  exposed 
  

   part 
  of 
  the 
  reef, 
  were 
  few 
  and 
  far 
  between 
  ; 
  they 
  present 
  all 
  the 
  appear- 
  

   ance 
  of 
  having 
  been 
  broken, 
  and 
  much 
  worn, 
  prior 
  to 
  deposition. 
  Large 
  

  

  sandstone, 
  containing 
  small 
  rounded 
  fragments 
  of 
  agate 
  and 
  quartz, 
  rarely 
  exceeding 
  an 
  

   inch, 
  and 
  generally 
  below 
  £ 
  inch 
  in 
  diameter. 
  

  

  " 
  The 
  second 
  principal 
  variety 
  is 
  the 
  same 
  coarse 
  sandstone 
  with 
  agate 
  pebbles, 
  the 
  latter, 
  

   however, 
  being 
  neither 
  numerous 
  nor 
  conspicuous, 
  without 
  any 
  of 
  the 
  rounded 
  blocks 
  of 
  

   sandstone."
