  represented 
  in 
  the 
  figure, 
  but 
  there 
  is 
  shown 
  at 
  D 
  a 
  small 
  

   wedge 
  of 
  grit 
  which 
  is 
  faulted 
  into 
  the 
  main 
  slate 
  wedge 
  at 
  one 
  

   point. 
  The 
  principal 
  fault 
  plane 
  is 
  along 
  A-B, 
  but 
  there 
  has 
  

   also 
  been 
  considerable 
  movement 
  aloEg 
  A-C 
  and 
  in 
  some 
  of 
  the 
  

   beds 
  above, 
  which 
  have 
  siickensided 
  the 
  surface 
  of 
  the 
  grit. 
  

   The 
  various 
  small 
  cross-faults 
  and 
  minor 
  crumplings 
  are 
  irregu- 
  

   larly 
  intermingled 
  in 
  the 
  displacement, 
  and 
  I 
  did 
  not 
  attempt 
  to 
  

   work 
  them 
  out. 
  The 
  relations 
  below 
  the 
  cement 
  wedge 
  are 
  not 
  

   fully 
  exposed, 
  but 
  there 
  are 
  many 
  scattered 
  outcrops 
  in 
  the 
  

   vicinity 
  which 
  exhibit 
  the 
  beds 
  and 
  their 
  dips. 
  This 
  fault 
  is 
  

   probably 
  the 
  one 
  referred 
  to 
  by 
  Cook 
  in 
  his 
  " 
  Geology 
  of 
  New 
  

   Jersey," 
  *asa 
  local 
  inversion 
  of 
  the 
  fold 
  which 
  has 
  overturned 
  

   the 
  grit 
  on 
  to 
  the 
  cement.. 
  South 
  from 
  this 
  point 
  for 
  some, 
  

   distance 
  the] 
  e 
  are 
  no 
  outcrops 
  exhibiting 
  the 
  relations 
  of 
  this 
  

   fault, 
  owing 
  to 
  the 
  heavy 
  sand 
  cover. 
  It 
  crosses 
  the 
  railroad 
  

   about 
  a 
  mile 
  to 
  the 
  southward, 
  and 
  beyond 
  this 
  point 
  its 
  rela- 
  

   tions 
  are 
  clearly 
  exposed 
  in 
  continuous 
  outcrops 
  of 
  Shawangunk 
  

   grit. 
  It 
  gives 
  rise 
  to 
  a 
  sharp 
  cliff, 
  which 
  is 
  conspicuous 
  for 
  

   about 
  a 
  mile 
  and 
  a 
  half, 
  and 
  finally 
  dies 
  out, 
  apparently 
  with 
  

   the 
  termination 
  of 
  the 
  fault. 
  Its 
  relations 
  in 
  this 
  region 
  are 
  

   shown 
  in 
  the 
  last 
  section 
  on 
  plate 
  T 
  and 
  sections 
  I 
  and 
  II 
  of 
  plate 
  

   12. 
  Oaring 
  to 
  this 
  fault 
  the 
  cement 
  beds 
  cross 
  Kondout 
  creek 
  at 
  

   Kosendale 
  in 
  two 
  narrow 
  belts. 
  They 
  are 
  very 
  near 
  together 
  

   and 
  separated 
  by 
  small 
  tongues 
  of 
  lower 
  Tentaculite 
  beds 
  which 
  

   are 
  not 
  clearly 
  exposed. 
  The 
  easternmost 
  cement 
  belt 
  pitches 
  

   dovrn 
  to 
  the 
  northeast 
  and 
  is 
  cut 
  off 
  by 
  the 
  Tentaculite 
  and 
  Pen- 
  

   tanierus 
  limestones 
  along 
  the 
  west 
  side 
  of 
  the 
  fault. 
  The 
  west- 
  

   ern 
  belt 
  rises 
  gradually 
  to 
  the 
  northward 
  along 
  a 
  northeast 
  dip 
  

   and 
  extends 
  continuously 
  nearly 
  to 
  Whiteport 
  on 
  the 
  east 
  side 
  

   of 
  the 
  valle3 
  r 
  , 
  which 
  is 
  excavated 
  along 
  the 
  arch 
  of 
  the 
  Rosen- 
  

   dale-Whiteport 
  anticlinal. 
  The 
  eastern 
  limb 
  of 
  this 
  anticlinal 
  is 
  

   the 
  western 
  limb 
  of 
  the 
  synclinal 
  described 
  in 
  the 
  preceding 
  

   pages, 
  and 
  its 
  relations 
  are 
  shown 
  in 
  the 
  first, 
  second, 
  third 
  and 
  

   fourth 
  sections 
  on 
  plate 
  7 
  and 
  in 
  figures 
  7 
  and 
  S. 
  

  

  The 
  cement 
  mines 
  at 
  Rosendale 
  extend 
  down 
  the 
  east 
  slope 
  of 
  

   the 
  beds 
  and 
  to 
  the 
  northward 
  along 
  the 
  strike.
