﻿MARTABAN 
  GROUP.

  the 
  schistose 
  and 
  crystalline 
  characters 
  of 
  the 
  beds 
  are 
  seen 
  to 
  give 
  place 
  

   insensibly 
  to 
  the 
  granitoid 
  habit, 
  huge 
  masses 
  of 
  the 
  latter 
  type 
  of 
  

   rock 
  being 
  seen 
  weathering 
  out 
  of 
  the 
  softer 
  beds 
  of 
  the 
  former 
  character. 
  

   I 
  am 
  not 
  sufficiently 
  familiar 
  with 
  the 
  area 
  of 
  this 
  granitoid 
  rock 
  to 
  

   pronounce 
  confidently 
  that 
  none 
  of 
  it 
  is 
  true 
  granite, 
  but 
  I 
  am 
  greatly 
  

   inclined 
  to 
  question 
  if 
  any 
  is. 
  True 
  granite 
  undoubtedly 
  occurs 
  in 
  the 
  

   district 
  in 
  the 
  shape 
  of 
  granite 
  dykes 
  which 
  traverse 
  beds 
  referred 
  by 
  

   me 
  to 
  the 
  ' 
  Moulmeur' 
  group, 
  and 
  a 
  fortiori 
  of 
  course 
  the 
  present 
  one 
  like- 
  

   wise 
  ; 
  but 
  no 
  conclusive 
  evidence 
  has 
  yet 
  been 
  produced 
  that 
  the 
  largely 
  

   developed 
  granitoid 
  rock 
  of 
  Kyoukgyee, 
  Kyiktyo, 
  &c, 
  is 
  really 
  intrusive, 
  

   and 
  till 
  this 
  is 
  produced, 
  I 
  do 
  not 
  consider 
  its 
  mere 
  lithological 
  aspect 
  

   as 
  sufficient 
  for 
  the 
  purpose. 
  This 
  view, 
  however, 
  is 
  avowedly 
  put 
  forward 
  

   from 
  an 
  extremely 
  limited 
  acquaintance 
  with 
  the 
  area 
  occupied 
  by 
  the 
  

   rock 
  in 
  question 
  and 
  in 
  view 
  of 
  the 
  extremely 
  deceptive 
  appearance 
  which 
  

   the 
  more 
  massive 
  members 
  of 
  a 
  gneissose 
  group 
  occasionally 
  assume, 
  pre- 
  

   senting 
  the 
  appearance 
  of 
  a 
  true 
  granite, 
  though 
  essentially 
  not 
  so, 
  

   if 
  we 
  correctly 
  restrict 
  that 
  term 
  to 
  a 
  rock 
  of 
  intrusive 
  origin. 
  In 
  the 
  

   ordinary 
  acceptation 
  of 
  the 
  term, 
  however, 
  this 
  rock 
  may 
  be 
  termed 
  

   granite, 
  and 
  the 
  peculiar 
  manner 
  in 
  which 
  it 
  occasionally 
  exfoliates 
  

   gives 
  rise 
  to 
  the 
  picturesque 
  hills 
  so 
  well 
  depicted 
  by 
  Mr. 
  Parish's 
  pencil. 
  

  

  From 
  the 
  little 
  I 
  saw 
  of 
  the 
  relation 
  of 
  the 
  Martaban 
  and 
  Moulmein 
  

   groups, 
  I 
  judged 
  that, 
  in 
  places 
  at 
  least, 
  the 
  former 
  constituted 
  the 
  higher 
  

   hills, 
  whilst 
  the 
  lower 
  country 
  was 
  occupied 
  by 
  the 
  latter 
  ; 
  but 
  my 
  oppor- 
  

   tunities 
  were 
  too 
  limited 
  to 
  allow 
  of 
  safely 
  generalizing 
  from 
  such 
  data, 
  

   neither 
  can 
  I 
  say 
  if 
  the 
  last 
  group 
  rests 
  immediately 
  on 
  • 
  the 
  present 
  one 
  

   in 
  Martaban 
  and 
  the 
  Yunzalin 
  district, 
  or 
  if 
  any 
  representatives 
  of 
  the 
  

   * 
  Mergui' 
  group 
  of 
  the 
  Southern 
  provinces 
  intervene, 
  as 
  is 
  probably 
  the 
  

   case. 
  The 
  denudation, 
  however, 
  has 
  been 
  enormous 
  to 
  which 
  these 
  

   Palaeozoic 
  beds 
  have 
  been 
  subjected, 
  to 
  which 
  is 
  due 
  the 
  curiously 
  

   isolated 
  fashion 
  in 
  which 
  so 
  many 
  of 
  the 
  hills 
  and 
  ranges 
  composed 
  of 
  

   them 
  stand 
  in 
  the 
  vicinity 
  of 
  Moulmein 
  and 
  elsewhere.
