  Linton. 
  — 
  Outside 
  the 
  western 
  edge 
  of 
  the 
  visible 
  coal-field 
  we 
  have 
  

   three 
  localities 
  in 
  which 
  the 
  Permians 
  have 
  been 
  observed. 
  At 
  the 
  

   village 
  of 
  Linton, 
  about 
  one 
  mile 
  south-west 
  of 
  Gresley 
  Station, 
  the 
  

   breccias 
  crop 
  out 
  at 
  the 
  surface 
  as 
  shown 
  in 
  the 
  one-inch 
  map 
  ; 
  and 
  

   a 
  few 
  years 
  ago 
  there 
  was 
  exposed 
  a 
  section 
  which 
  is 
  figured 
  at 
  p. 
  59 
  

   of 
  the 
  Survey 
  Memoir. 
  This 
  section 
  is 
  now 
  obliterated, 
  but 
  traces 
  

   of 
  the 
  breccias 
  of 
  the 
  usual 
  Permian 
  type 
  can 
  still 
  be 
  seen 
  in 
  the 
  

   private 
  road 
  of 
  the 
  Manor 
  House. 
  The 
  late 
  Rev. 
  W. 
  H. 
  Coleman,- 
  

   in 
  his 
  ' 
  Outlines 
  of 
  the 
  Geology 
  of 
  Leicestershire,' 
  p. 
  23, 
  states 
  that 
  

   in 
  a 
  well 
  at 
  Linton 
  -±2 
  ft. 
  6 
  in. 
  of 
  Permian 
  were 
  found 
  overlying 
  the 
  

   Coal-measures. 
  

  

  Ketherseal 
  Colliery. 
  — 
  At 
  the 
  Xetherseal 
  Colliery 
  *, 
  I5 
  mile 
  west 
  of 
  

   Overseal, 
  the 
  Trias 
  was 
  found 
  to 
  be 
  213 
  feet 
  thick 
  (the 
  Lower 
  Keuper 
  

   75 
  ft. 
  and 
  the 
  Bunter 
  138 
  ft.), 
  and 
  between 
  this 
  and 
  the 
  Coal-measures 
  

   the 
  records 
  of 
  the 
  sinking 
  note 
  the 
  existence 
  of 
  a 
  series 
  of 
  grey 
  

   sandstones 
  with 
  soft 
  blue 
  partings, 
  and 
  a 
  bed 
  of 
  red 
  marl 
  at 
  the 
  

   base 
  7 
  ft. 
  10 
  in. 
  in 
  thickness. 
  The 
  total 
  thickness 
  of 
  these 
  beds, 
  

   which 
  from 
  their 
  description 
  I 
  have 
  no 
  hesitation 
  in 
  referring 
  to 
  the 
  

   Permian, 
  is 
  37 
  ft. 
  6 
  in. 
  ; 
  this 
  is 
  in 
  excess 
  of 
  anything 
  I 
  have 
  found 
  

   further 
  to 
  the 
  east. 
  

  

  Coton 
  Park 
  Colliery. 
  — 
  At 
  the 
  Coton 
  Park 
  Colliery, 
  § 
  mile 
  west 
  of 
  

   Gresley 
  Station, 
  about 
  7 
  ft. 
  9 
  in. 
  of 
  reddish 
  breccia 
  were 
  passed 
  

   through. 
  This 
  rested 
  upon 
  about 
  14 
  ft. 
  of 
  purple 
  marls, 
  which, 
  

   from 
  the 
  description 
  given 
  to 
  me 
  by 
  Mr, 
  Gresley, 
  I 
  should 
  class 
  

   as 
  Coal-measures. 
  Mr. 
  Molyneux, 
  at 
  p. 
  157 
  of 
  his 
  ' 
  History 
  of 
  

   Burton- 
  on-Trent,' 
  describes 
  the 
  rocks 
  immediately 
  below 
  the 
  Trias 
  

   at 
  this 
  point 
  as 
  consisting 
  of 
  90 
  ft. 
  of 
  " 
  grits 
  and 
  red 
  and 
  mottled 
  

   clays 
  (containing 
  Stigmaria 
  and 
  other 
  plant-remains), 
  intersected 
  by 
  

   breccias 
  resembling 
  those 
  of 
  the 
  Leather 
  Mill 
  section 
  " 
  (Hartshorn 
  

   Brook). 
  The 
  breccias 
  certainly 
  do 
  not 
  intersect 
  the 
  grits 
  and 
  mottled 
  

   clays, 
  but 
  overlie 
  them 
  f. 
  

  

  measures. 
  This 
  interpretation 
  cannot, 
  however, 
  be 
  the 
  correct 
  one, 
  as 
  I 
  have 
  

   found, 
  on 
  carefully 
  following 
  the 
  line 
  of 
  junction 
  of 
  the 
  Trias 
  and 
  Coal-measures 
  

   with 
  the 
  boring-rod, 
  that 
  it 
  is 
  so 
  sinuous 
  as 
  utterly 
  to 
  forbid 
  the 
  idea 
  of 
  its 
  being 
  

   a 
  line 
  of 
  fault. 
  Moreover, 
  a 
  very 
  thin 
  outcrop 
  of 
  Permian 
  occurs 
  300 
  yds. 
  west 
  

   of 
  Geary 
  House, 
  intercalated 
  between 
  the 
  Lower 
  Keuper 
  and 
  the 
  Coal-measures. 
  

   The 
  underground 
  workings 
  in 
  the 
  adjoining 
  collieries 
  also 
  agree 
  with 
  the 
  surface- 
  

   indications, 
  and 
  prove 
  the 
  unbroken 
  continuity 
  of 
  the 
  Coal-measures 
  between 
  

   the 
  Bretby 
  Collieries 
  and 
  the 
  disused 
  Anglesea 
  Pit, 
  south 
  of 
  Moat 
  Bank. 
  

  

  The 
  absence 
  of 
  the 
  Bunter 
  here 
  is 
  consequently 
  not 
  due 
  to 
  the 
  faulting, 
  but 
  

   to 
  an 
  overlap 
  of 
  Lower 
  Keuper. 
  We 
  have 
  indications, 
  however, 
  both 
  to 
  the 
  

   east 
  and 
  to 
  the 
  west, 
  of 
  the 
  occurrence 
  of 
  Bunter 
  Conglomerate, 
  in 
  the 
  latter 
  case 
  

   in 
  sinkings, 
  and 
  in 
  the 
  former 
  in 
  the 
  small 
  outlier 
  of 
  Conglomerate 
  resting 
  on 
  

   the 
  Coal-measures 
  at 
  Bretby 
  Colliery. 
  Consequently 
  we 
  have 
  a 
  small 
  area 
  

   near 
  Brizlincote 
  Hall 
  which 
  cannot 
  have 
  been 
  submerged 
  in 
  Triassic 
  times 
  until 
  

   a 
  period 
  later 
  than 
  the 
  deposition 
  of 
  the 
  Bunter. 
  This 
  small 
  patch 
  of 
  Car- 
  

   boniferous 
  land 
  must 
  either 
  have 
  been 
  a 
  promontory 
  stretching 
  westward 
  from 
  

   the 
  mainland, 
  or, 
  what 
  is 
  more 
  likely, 
  a 
  small 
  island 
  close 
  to 
  the 
  shore, 
  which 
  

   did 
  not 
  become 
  completely 
  submerged 
  until 
  after 
  the 
  deposition 
  of 
  the 
  greater 
  

   part 
  of 
  the 
  Lower 
  Keuper 
  Sandstones 
  of 
  the 
  neighbourhood.
