  GEOLOGY 
  OF 
  PEGU. 
  

  

  Beyond 
  carbonaceous 
  markings, 
  I 
  noticed 
  no 
  fossil 
  whatever 
  j 
  many 
  of 
  

   the 
  beds 
  however 
  are 
  badly 
  seen, 
  and 
  the 
  chief 
  value 
  of 
  the 
  section 
  con- 
  

   sists 
  in 
  showing 
  the 
  astonishing 
  thickness 
  of 
  this 
  early 
  Tertiary 
  group. 
  

   It 
  must, 
  however, 
  be 
  remarked 
  that 
  in 
  the 
  total 
  absence, 
  from 
  this 
  lower 
  

   portion 
  of 
  what 
  I 
  have 
  designated 
  the 
  Nummulitic 
  group, 
  of 
  all 
  fossil 
  

   evidence 
  as 
  to 
  its 
  age, 
  it 
  is 
  possible 
  that 
  some 
  of 
  the 
  beds 
  may 
  be 
  of 
  a 
  

   greater 
  age, 
  though 
  this 
  cannot 
  with 
  certainty 
  be 
  either 
  affirmed 
  or 
  

   denied. 
  

  

  At 
  the 
  point 
  where 
  the 
  above 
  section 
  is 
  taken, 
  the 
  Nummulitic 
  

   group 
  is 
  wider 
  than 
  almost 
  anywhere 
  else, 
  its 
  width 
  being 
  thirteen 
  miles 
  ; 
  

   opposite 
  Myanong 
  the 
  width 
  is 
  only 
  ten 
  miles, 
  and 
  at 
  Henzadah 
  not 
  

   more 
  than 
  two. 
  

  

  South 
  of 
  Henzadah 
  and 
  in 
  the 
  Bassein 
  district 
  the 
  Nummulitic 
  beds 
  

   are 
  much 
  covered 
  up 
  by 
  surface 
  detritus, 
  and 
  their 
  width 
  inconsiderable. 
  

   South 
  of 
  Ngaputau, 
  near 
  Thamandewah, 
  a 
  considerable 
  outcrop 
  of 
  Num- 
  

   mulitic 
  limestone 
  is 
  seen, 
  and 
  Long 
  Island 
  in 
  the 
  Bassein 
  river, 
  and 
  much 
  

   of 
  the 
  o-round 
  to 
  the 
  Eastward 
  consist 
  of 
  unaltered 
  Nummulitic 
  strata. 
  

   At 
  Pyeno'makhyoung, 
  West 
  of 
  Long 
  Island, 
  Nummulitic 
  limestone 
  occurs 
  

   near 
  the 
  bank 
  of 
  the 
  stream 
  ; 
  and 
  Pooriam 
  Point, 
  thirty 
  miles 
  still 
  further 
  

   South, 
  consists 
  of 
  Nummulitic 
  sandstone 
  ; 
  so 
  that 
  from 
  the 
  frontier 
  to 
  the 
  

   gulf 
  of 
  Martaban, 
  the 
  beds 
  of 
  this 
  group 
  constitute 
  a 
  belt 
  of 
  ground 
  

   flanking 
  the 
  Arakan 
  hills 
  on 
  the 
  East 
  for 
  their 
  entire 
  length. 
  West 
  of 
  the 
  

   Arakan 
  range 
  Nummulitic 
  limestone 
  occurs 
  in 
  two 
  spots 
  near 
  Kyeantalee, 
  

   but 
  the 
  question 
  of 
  what 
  rocks 
  the 
  Arakan 
  range 
  is 
  mainly 
  composed 
  of, 
  I 
  

   shall 
  presently 
  discuss 
  under 
  another 
  head. 
  In 
  a 
  manuscript 
  report 
  dated 
  

   1862, 
  Mr. 
  W. 
  Blanford 
  makes 
  the 
  following 
  remarks 
  on 
  the 
  Long 
  Island 
  

   beds 
  : 
  " 
  Extensive 
  areas 
  of 
  low 
  hills 
  composed 
  of 
  rock 
  also 
  occur 
  to 
  the 
  

   East 
  of 
  the 
  river, 
  especially 
  in 
  the 
  neighbourhood 
  of 
  the 
  sea. 
  Pooriam 
  

   Point, 
  for 
  instance, 
  is 
  composed 
  of 
  a 
  peculiar 
  white 
  or 
  whitish 
  green 
  

   argillaceous 
  sandstone 
  which, 
  although 
  containing 
  Nummulites, 
  appears 
  

   to 
  be 
  one 
  of 
  the 
  highest 
  beds 
  of 
  the 
  Nummulitic 
  group 
  in 
  the 
  district.
