  ON 
  THE 
  PER3IIAN 
  

  

  reous 
  matrix. 
  The 
  boring 
  terminated 
  after 
  passing 
  through 
  34 
  feet 
  

   of 
  this 
  rock, 
  which 
  resembles 
  very 
  much 
  in 
  general 
  appearance 
  a 
  

   breccia 
  which 
  occurs 
  at 
  the 
  base 
  of 
  the 
  Hartshill 
  quartzite, 
  at 
  the 
  

   entrance 
  to 
  Boon's 
  Quarry, 
  near 
  Nuneaton. 
  There 
  are 
  several 
  

   reasons 
  for 
  believing 
  that 
  this 
  breccia 
  does 
  not 
  naturally 
  underlie 
  

   the 
  shales 
  of 
  the 
  boring, 
  but 
  that 
  it 
  belongs 
  to 
  a 
  much 
  lower 
  horizon 
  

   than 
  the 
  Stockingford 
  Shales, 
  and 
  owes 
  its 
  present 
  position 
  to 
  fault- 
  

   ing. 
  In 
  the 
  first 
  place, 
  we 
  may 
  be 
  pretty 
  certain 
  that 
  the 
  shales 
  

   passed 
  through 
  in 
  the 
  boring 
  are 
  not 
  the 
  Lower 
  Stockingford, 
  since 
  

   no 
  black 
  shales 
  such 
  as 
  immediately 
  overlie 
  the 
  breccia 
  occur 
  at 
  this 
  

   horizon. 
  Secondly, 
  as 
  pointed 
  out 
  to 
  me 
  by 
  Prof. 
  Lapworth, 
  the 
  

   shales 
  passed 
  through 
  just 
  before 
  the 
  breccia 
  was 
  struck 
  are 
  

   very 
  much 
  " 
  smashed 
  " 
  and 
  slickensided. 
  Then, 
  again, 
  it 
  is 
  op- 
  

   posed 
  to 
  the 
  physics 
  of 
  sedimentation 
  to 
  find 
  deep-water 
  deposits, 
  

   like 
  those 
  of 
  the 
  Lower 
  Silurian 
  Shales, 
  abruptly 
  succeeding 
  breccias 
  

   without 
  any 
  signs 
  of 
  a 
  passage. 
  Taking 
  all 
  these 
  facts 
  into 
  con- 
  

   sideration, 
  I 
  think 
  there 
  can 
  be 
  no 
  doubt 
  that 
  the 
  Bosworth 
  Wharf 
  

   boring, 
  at 
  a 
  depth 
  of 
  1330 
  feet, 
  passed 
  through 
  a 
  fault 
  which 
  throws 
  

   up 
  the 
  basement-beds 
  of 
  the 
  Hartshill 
  quartzite 
  on 
  the 
  east 
  in 
  con- 
  

   tact 
  with 
  the 
  middle 
  portion 
  of 
  the 
  Stockingford 
  Shales 
  on 
  the 
  west. 
  

  

  (3) 
  Boring 
  at 
  Kingshill 
  Spinney. 
  — 
  This 
  boring 
  was 
  carried 
  to 
  a 
  

   total 
  depth 
  of 
  1030 
  feet, 
  and 
  appears 
  to 
  have 
  been 
  in 
  the 
  Trias 
  

   throughout. 
  The 
  lower 
  part 
  is 
  in 
  a 
  coarse 
  sandstone 
  containing 
  

   rounded 
  pebbles, 
  evidently 
  the 
  Bunter 
  Conglomerates, 
  which 
  are 
  

   more 
  fully 
  developed 
  six 
  miles 
  further 
  west, 
  near 
  Poles 
  worth, 
  and 
  

   again 
  eight 
  miles 
  N.N.W., 
  on 
  the 
  margin 
  of 
  the 
  Ashby 
  Coal-field. 
  

   Taken 
  in 
  conjunction 
  with 
  the 
  other 
  borings 
  of 
  the 
  neighbourhood, 
  

   the 
  results 
  are 
  of 
  interest 
  as 
  fixing 
  the 
  easterly 
  limit 
  of 
  the 
  Bunter 
  

   in 
  this 
  part 
  of 
  the 
  country. 
  

  

  These 
  three 
  borings 
  at 
  Market 
  Bosworth 
  are 
  situated 
  approxi- 
  

   mately 
  along 
  a 
  line 
  running 
  N.E. 
  and 
  S.W., 
  and 
  they 
  prove 
  beyond 
  

   doubt 
  the 
  important 
  fact 
  that, 
  in 
  this 
  neighbourhood, 
  just 
  as 
  further 
  

   south, 
  near 
  Elmesthorpe, 
  the 
  older 
  Palaeozoic 
  rocks 
  underlying 
  the 
  

   Trias 
  rise 
  rapidly 
  towards 
  the 
  north-east, 
  and 
  that 
  a 
  line 
  joining 
  

   Market 
  Bosworth 
  and 
  Sapcote 
  Freeholt 
  must 
  mark 
  the 
  axis 
  of 
  a 
  sub- 
  

   Triassic 
  anticlinal 
  ridge 
  of 
  the 
  older 
  rocks. 
  

  

  Now 
  the 
  direction 
  of 
  this 
  line 
  is 
  about 
  N.N.W. 
  and 
  S.S.E., 
  and 
  it 
  

   is, 
  consequently, 
  parallel 
  with 
  the 
  Nuneaton-Hartshill 
  and 
  Charmvood 
  

   axes 
  of 
  elevation, 
  and 
  also 
  with 
  the 
  general 
  direction 
  of 
  the 
  major 
  

   folds 
  and 
  faults 
  of 
  the 
  Leicestershire 
  Coal-field 
  further 
  north. 
  On 
  the 
  

   western 
  side 
  of 
  this 
  ridge 
  the 
  general 
  dip 
  and 
  relative 
  position 
  of 
  

   the 
  Upper 
  Cambrian 
  and 
  the 
  Coal-measures, 
  when 
  these 
  latter 
  are 
  

   present, 
  must 
  be 
  the 
  same 
  as 
  in 
  the 
  neighbourhood 
  of 
  Xuneaton. 
  

   We 
  have 
  shown 
  reason 
  for 
  believing 
  that 
  this 
  is 
  a 
  faulted 
  anticlinal 
  

   with 
  a 
  downthrow 
  to 
  the 
  west 
  ; 
  and 
  if 
  we 
  could 
  sweep 
  away 
  the 
  

   covering 
  of 
  Triassic 
  sediment 
  we 
  should 
  doubtless 
  find 
  the 
  Harts- 
  

   hill 
  quartzites 
  and 
  the 
  equivalents 
  of 
  the 
  Caldecote 
  Series 
  rising 
  from 
  

   under 
  the 
  Stockingford 
  shales 
  a 
  little 
  to 
  the 
  north-east 
  of 
  Market 
  

   Bosworth. 
  Since 
  we 
  know 
  with 
  certainty 
  that 
  the 
  Carboniferous 
  

   strata 
  were 
  denuded 
  from 
  the 
  older 
  rocks 
  in 
  Permian 
  times 
  (for 
  at
