  GEOLOGY 
  OF 
  KATHIAWAR 
  PENINSULA 
  IN 
  GUZERAT, 
  

  

  banks 
  of 
  a 
  watercourse, 
  where 
  they 
  are 
  overlaid 
  by 
  the 
  traps 
  of* 
  the 
  sur- 
  

   face. 
  The 
  basal 
  traps 
  are, 
  as 
  usual, 
  much 
  decomposed, 
  friable, 
  and 
  very 
  

   various, 
  and 
  are 
  associated 
  and 
  mingled 
  in 
  a 
  confused 
  manner 
  with 
  the 
  

   sedimentary 
  beds 
  ; 
  some 
  of 
  the 
  latter 
  have 
  even 
  a 
  trappean 
  aspect 
  ; 
  and 
  

   it 
  seems 
  probable 
  they 
  were 
  being" 
  deposited 
  when 
  the 
  trappean 
  epoch 
  

   set 
  in. 
  

  

  East 
  of 
  Morvi 
  town 
  the 
  traps 
  are 
  very 
  thin, 
  and 
  several 
  small 
  inliers 
  

  

  are 
  exposed 
  of 
  varying 
  sandstones 
  that 
  I 
  am 
  

   Inliers 
  east 
  of 
  Morvi. 
  

  

  disposed 
  to 
  regard 
  as 
  members 
  of 
  the 
  present 
  

  

  group. 
  The 
  red 
  unsorted 
  softish 
  sandstone 
  is 
  prevalent, 
  and 
  asso- 
  

   ciated 
  with 
  other 
  light-coloured 
  slightly 
  calcareous 
  sandstones, 
  with 
  

   some 
  argillaceous 
  bands. 
  The 
  inlier 
  south 
  of 
  Ghotu 
  is 
  a 
  tough 
  

   compact, 
  rather 
  calcareous 
  gritty 
  sandstone. 
  It 
  is 
  cross-bedded, 
  and 
  

   appears 
  tilted 
  four 
  or 
  five 
  degrees 
  to 
  east- 
  30°- 
  south. 
  A 
  similar 
  rock 
  

   crops 
  out 
  below 
  the 
  trap 
  scarp 
  near 
  Paneli, 
  and 
  may 
  be 
  traced 
  nearly 
  as 
  

   far 
  as 
  Gidach. 
  Umia 
  sandstones 
  occupy 
  the 
  low 
  ground 
  and 
  plains. 
  

   In 
  the 
  scarps 
  of 
  the 
  two 
  outlying 
  trap-capped 
  hills 
  south 
  of 
  Paneli, 
  red 
  

   sandstones 
  varying 
  to 
  orange 
  or 
  yellow, 
  unsorted 
  in 
  texture 
  and 
  gritty, 
  

   and 
  slightly 
  calcareous 
  in 
  part, 
  form 
  one-third 
  of 
  the 
  hill-sides. 
  At 
  

   the 
  southernmost 
  of 
  the 
  two 
  hills, 
  the 
  unsorted 
  gritty 
  sandstones 
  are 
  

   more 
  massively 
  bedded, 
  and 
  are 
  seen 
  to 
  rest 
  upon 
  the 
  somewhat 
  uneven 
  

   surface 
  of 
  the 
  Umia 
  sandstones 
  of 
  the 
  plain. 
  

  

  Isolated 
  hillocks 
  of 
  similar 
  gritty 
  slightly 
  calcareous 
  sandstones 
  

   Inliers 
  south-west 
  of 
  occur 
  in 
  the 
  Wadhwan 
  district, 
  forming 
  inliers, 
  

   Wadhwan. 
  which 
  protrude, 
  as 
  it 
  were, 
  from 
  under 
  the 
  thin 
  

  

  traps 
  of 
  the 
  plain. 
  The 
  matrix 
  of 
  the 
  sandstone 
  is 
  sometimes 
  

   observed 
  to 
  be 
  porcellaneous. 
  The 
  sandstones 
  in 
  the 
  area 
  between 
  the 
  

   two 
  Bhogawa 
  rivers, 
  are 
  often 
  locally 
  disturbed, 
  being 
  tilted 
  as 
  much 
  

   as 
  60°, 
  or 
  more, 
  from 
  the 
  horizontal 
  : 
  and 
  the 
  rock 
  occasionally 
  

   presents 
  the 
  appearance 
  of 
  induration 
  and 
  crush 
  where 
  slickensides 
  

   have 
  been 
  developed. 
  The 
  displacement, 
  in 
  some 
  instances, 
  appears 
  

   to 
  be 
  merely 
  superficial; 
  as 
  though 
  the 
  surface 
  beds, 
  while 
  yet 
  uncon- 
  

   solidated, 
  had 
  been 
  ploughed 
  up 
  by 
  the 
  flowing 
  lava 
  — 
  erupted 
  through
