  GEOLOGY 
  OF 
  KATHIAWAR 
  PENINSULA 
  IN 
  GUZERAT. 
  

  

  organisms, 
  among 
  which 
  any 
  distinct 
  or 
  recognisable 
  fossil 
  can 
  seldom 
  

   be 
  detected. 
  At 
  Khorasa, 
  east 
  of 
  Chorwar, 
  the 
  rock 
  is 
  a 
  hard 
  tough 
  

   marly 
  limestone, 
  buff 
  coloured, 
  with 
  numerous 
  fragmentary 
  fossils 
  of 
  

   bryozoa, 
  corals, 
  &c. 
  A 
  coral 
  mass 
  of 
  dark 
  close 
  limestone 
  was 
  also 
  

   observed 
  in 
  this 
  locality. 
  

  

  The 
  Gaj 
  rocks 
  continue, 
  for 
  some 
  distance 
  north-westerly, 
  as 
  an 
  

   irregular 
  fringe 
  along 
  the 
  margin 
  of 
  the 
  traps, 
  with 
  only 
  a 
  very 
  narrow 
  

   band 
  of 
  the 
  lateritics 
  intervening. 
  They 
  are 
  broken 
  through 
  at 
  the 
  

   mouth 
  of 
  the 
  Ojat 
  river, 
  where 
  the 
  rocks 
  have 
  undergone 
  much 
  

   denudation; 
  and 
  the 
  alluvium 
  overlapping 
  them 
  has 
  invaded 
  the 
  trap 
  

   area 
  for 
  some 
  way 
  up 
  the 
  valley. 
  

  

  The 
  tertiaries 
  are 
  nowhere 
  exposed 
  in 
  the 
  delta 
  of 
  the 
  Bhadar 
  river; 
  

   nor 
  seen 
  again 
  till 
  the 
  latitude 
  of 
  Porbandar 
  is 
  reached 
  ; 
  where 
  a 
  broad 
  

   spread 
  extends 
  for 
  about 
  17 
  miles 
  near 
  the 
  coast, 
  to 
  within 
  a 
  few 
  miles 
  

   of 
  the 
  Miani 
  creek. 
  

  

  The 
  boundary 
  lines 
  within 
  this 
  area 
  are 
  complicated, 
  on 
  the 
  one 
  

   hand, 
  by 
  inliers 
  of 
  lateritic 
  rocks, 
  which 
  protrude 
  as 
  crags 
  and 
  hummocks 
  

   considerably 
  above 
  the 
  present 
  level 
  of 
  the 
  tertiaries 
  ; 
  and, 
  on 
  the 
  other, 
  

   by 
  invading 
  inlets 
  of 
  alluvium, 
  where 
  denudation 
  has 
  permitted 
  it. 
  

   Much 
  of 
  the 
  ground 
  north 
  and 
  north-west 
  of 
  Porbandar 
  is 
  sheeted 
  

   with 
  miliolite 
  and 
  other 
  sub-recent 
  accumulations, 
  which 
  along 
  the 
  

   seaboard 
  form 
  a 
  succession 
  of 
  beds 
  of 
  solid 
  rock, 
  and 
  it 
  is 
  by 
  no 
  

   means 
  an 
  easy 
  matter 
  to 
  lay 
  down 
  a 
  boundary 
  line 
  between 
  these 
  and 
  

   the 
  tertiary 
  beds. 
  

  

  At 
  Bharwara, 
  nine 
  miles 
  north 
  of 
  Porbandar, 
  a 
  yellow 
  marly 
  lime- 
  

   stone 
  contains 
  numerous 
  coral 
  stalks 
  (Stylopkora), 
  a 
  few 
  single 
  corals, 
  

   and, 
  more 
  sparingly, 
  the 
  rotund 
  variety 
  of 
  Venus 
  cancellata 
  ; 
  one 
  spe- 
  

   cimen 
  of 
  Turritella 
  vittata 
  was 
  also 
  obtained. 
  

  

  In 
  the 
  neighbourhood 
  of 
  Visawar, 
  six 
  miles 
  below 
  Miani, 
  and 
  at 
  

   Tiikra, 
  two 
  miles 
  nearer 
  Miani, 
  very 
  rag-like 
  disintegrating 
  Gaj 
  beds 
  

   yielded 
  the 
  following 
  fossils 
  : 
  — 
  

  

  Cephalopoda. 
  

   Sepia, 
  sp. 
  (cuttlebone) 
  .
