  These 
  are 
  prolonged 
  for 
  nearly 
  a 
  mile 
  to 
  the 
  south-west, 
  and 
  are 
  

   much 
  interfered 
  with 
  and 
  hardened 
  by 
  protrusions 
  of 
  gabbro, 
  which 
  

   has 
  been 
  forced 
  through 
  the 
  beds 
  in 
  a 
  complicated 
  plexus 
  of 
  dykes 
  

   and 
  veins. 
  

  

  The 
  Stinchar 
  beds 
  of 
  this 
  locality 
  lie 
  apparently 
  between 
  two 
  

   converging 
  faults, 
  which 
  appear 
  to 
  be 
  the 
  prolongations 
  of 
  those 
  

   which 
  bound 
  the 
  Skalloch-Hill 
  area. 
  These 
  unite 
  to 
  the 
  south-west 
  

   into 
  a 
  single 
  line, 
  which 
  may 
  be 
  most 
  conveniently 
  regarded 
  as 
  part 
  

   of 
  the 
  Craigwells 
  dislocation, 
  which 
  is 
  continued 
  in 
  this 
  direction 
  

   into 
  the 
  metamorphic 
  rocks 
  of 
  the 
  valley 
  of 
  the 
  Lendal.

  Aldons 
  Quarry. 
  — 
  Before 
  entering 
  upon 
  the 
  study 
  of 
  the 
  scat- 
  

   tered 
  exposures 
  of 
  the 
  Stinchar 
  calcareous 
  series 
  to 
  the 
  north 
  and 
  west 
  

   of 
  the 
  Benan-Hill 
  ridge, 
  it 
  will 
  be 
  advisable 
  to 
  turn 
  aside 
  for 
  a 
  while, 
  

   and 
  examine 
  the 
  magnificent 
  exhibition 
  of 
  these 
  rocks 
  in 
  the 
  quarries 
  

   at 
  Aldons 
  and 
  their 
  extension 
  in 
  the 
  south-west. 
  The 
  massive 
  con- 
  

   glomerates 
  of 
  Benan 
  Hill 
  are 
  continued 
  uninterruptedly 
  from 
  the 
  

   highest 
  points 
  of 
  the 
  Benan 
  ridge 
  across 
  the 
  lower 
  valley 
  of 
  the 
  Assel 
  

   Water 
  into 
  the 
  steep 
  slopes 
  of 
  Aldons 
  Hill 
  west 
  of 
  Pinmore. 
  About 
  a 
  

   mile 
  south-west 
  of 
  Pinmore 
  Bridge 
  the 
  great 
  conglomerate 
  is 
  reduced 
  

   almost 
  to 
  a 
  point 
  between 
  two 
  converging 
  faults, 
  which 
  have 
  thrown 
  

   it 
  down 
  in 
  a 
  narrow 
  synclinal 
  among 
  the 
  Ballantrae 
  metamorphic 
  

   and 
  igneous 
  rocks. 
  The 
  limestone 
  is 
  seen 
  coming 
  out 
  from 
  below 
  

   the 
  Benan 
  Conglomerate 
  on 
  both 
  sides 
  of 
  this 
  synclinal 
  ; 
  and 
  its 
  

   relations 
  to 
  the 
  rocks 
  above 
  and 
  below 
  are 
  admirably 
  shown 
  in 
  the 
  

   large 
  quarries 
  which 
  have 
  long 
  been 
  opened 
  at 
  this 
  locality. 
  

  

  In 
  the 
  north-west 
  quarry 
  and 
  in 
  the 
  sides 
  of 
  the 
  roadway 
  leading 
  

   thence 
  towards 
  the 
  valley 
  of 
  the 
  Stinchar 
  we 
  have 
  an 
  excellent 
  

   exhibition 
  of 
  the 
  rocks.
