﻿SUB-RECENT 
  AND 
  ALLUVIAL 
  BEDS,

  indifferently 
  cemented, 
  associated 
  with 
  the 
  miliolite, 
  and 
  passing 
  the 
  one 
  

   into 
  the 
  other. 
  At 
  Gopnath, 
  some 
  of 
  the 
  beds 
  in 
  the 
  section 
  are 
  earthy 
  

   and 
  rubbly, 
  being 
  in 
  part 
  largely 
  made 
  up 
  of 
  nodular 
  concretions 
  In 
  

   Land 
  shells 
  in 
  the 
  some 
  of 
  these 
  impure 
  miliolitic 
  beds, 
  a 
  few 
  fresh- 
  

   miliolite. 
  water 
  shells 
  have 
  been 
  found 
  from 
  time 
  to 
  time 
  j 
  

  

  the 
  following 
  five 
  species 
  of 
  existing 
  land 
  shells 
  were 
  noted 
  by 
  Mr. 
  Theo- 
  

   bald 
  in 
  1858, 
  — 
  Bnlimm 
  insularis> 
  B. 
  punctatus, 
  two 
  Helices^ 
  and 
  a 
  

   Cyclotus. 
  

  

  It 
  is 
  not 
  unreasonable 
  to 
  expect 
  that 
  such 
  light 
  shells 
  would 
  be 
  

   floated 
  down 
  by 
  small 
  streams 
  or 
  floods, 
  and 
  become 
  entombed 
  in 
  a 
  

   marine 
  littoral 
  deposit, 
  which 
  this 
  evidently 
  is. 
  

  

  At 
  Mota 
  Kotra, 
  on 
  the 
  coast 
  south 
  of 
  Data, 
  there 
  are 
  overhanging 
  

   Blown 
  sand 
  inter- 
  c 
  ^ 
  ffs 
  in 
  which 
  a 
  mass 
  of 
  grey 
  softish 
  calcareous 
  

   stratified. 
  sandstone 
  is 
  seen 
  resting 
  upon 
  miliolite 
  lime- 
  

  

  stone, 
  and 
  having 
  a 
  similar 
  limestone 
  above 
  it. 
  The 
  grey 
  sandstone, 
  

   though 
  unbedded, 
  is 
  laminated 
  obliquely 
  in 
  various 
  directions, 
  after 
  the 
  

   manner 
  of 
  blown 
  sand 
  ; 
  and 
  it 
  seems 
  probable 
  that 
  much 
  of 
  the 
  grey 
  

   slightly 
  coherent 
  sandstone 
  consisted 
  of 
  blown 
  sand, 
  in 
  the 
  form 
  of 
  

   dunes 
  that 
  became 
  submerged 
  ; 
  and 
  the 
  sand 
  partially 
  cemented 
  by 
  per- 
  

   colation 
  of 
  lime 
  from 
  the 
  miliolite 
  beds. 
  

  

  The 
  subrecent 
  rocks 
  all 
  along 
  this 
  part 
  of 
  the 
  coast, 
  from 
  Gopnath 
  

   downwards, 
  are 
  similarly 
  constituted. 
  The 
  cliffs 
  at 
  Gadhara, 
  south 
  of 
  

   Mowa, 
  which 
  are 
  about 
  70 
  feet 
  in 
  height, 
  well 
  exemplify 
  the 
  irregular 
  

   mode 
  of 
  their 
  accumulation.

  Along 
  the 
  south-west 
  coast 
  in 
  the 
  neighbourhood 
  of 
  Patau 
  Verawal 
  

   Raised 
  beacb. 
  on 
  an(

  Mangrol, 
  the 
  sub-recent 
  sandy 
  beds 
  are 
  

   sontb-west 
  coast. 
  stronger, 
  and 
  represent 
  a 
  littoral 
  accumulation, 
  

  

  or 
  raised 
  beach 
  ; 
  for, 
  at 
  one 
  place, 
  I 
  obtained 
  many 
  well- 
  fossilized 
  shells, 
  

   such 
  as 
  Conus, 
  Cyprcea, 
  and 
  several 
  Pelecypoda. 
  The 
  harder 
  portions 
  

   of 
  this 
  rock, 
  not 
  always 
  on 
  the 
  same 
  horizon, 
  have 
  been 
  largely 
  quarried 
  

   for 
  an 
  inferior 
  building 
  stone, 
  while 
  other 
  portions 
  of 
  it 
  are 
  still 
  inco- 
  

   herent. 
  The 
  upper 
  part, 
  which 
  contains 
  the 
  shells, 
  is 
  coarse-grained 
  

   and 
  softish.
