﻿IRON 
  ORES 
  OF 
  THE 
  CLINTON 
  FORMATION 
  27 
  

  

  evidence 
  exists 
  that 
  a 
  part 
  of 
  the 
  upper 
  beds 
  hitherto 
  assigned 
  to 
  

   the 
  formation 
  may 
  belong 
  to 
  the 
  age 
  of 
  the 
  Rochester 
  shale. 
  

  

  The 
  section 
  at 
  this 
  locality, 
  as 
  given 
  by 
  C. 
  H. 
  Smyth 
  jr,

  is 
  as 
  

   follows 
  :

  It 
  is 
  manifest 
  that 
  the 
  formation 
  here 
  assumes 
  a 
  lithic 
  character 
  

   that 
  is 
  quite 
  different 
  from 
  the 
  succession 
  heretofore 
  described. 
  

   Above 
  the 
  upper 
  calcareous 
  sandstone 
  there 
  is 
  a 
  gap 
  of 
  undetermined 
  

   extent 
  before 
  the 
  Lockport 
  is 
  reached. 
  In 
  the 
  sections 
  to 
  the 
  east, 
  

   occurs 
  a 
  heavy 
  gray 
  sandstone, 
  70 
  feet 
  thick 
  as 
  a 
  maximum, 
  form- 
  

   ing 
  what 
  has 
  been 
  considered 
  the 
  uppermost 
  member 
  of 
  the 
  Clinton. 
  

  

  Herkimer 
  county. 
  The 
  eastern 
  end 
  of 
  the 
  Clinton 
  belt 
  crosses 
  

   southern 
  Herkimer 
  county 
  into 
  Otsego 
  county. 
  The 
  relations 
  in 
  

   this 
  region 
  are 
  not 
  well 
  known, 
  and 
  it 
  is 
  impossible 
  as 
  yet 
  to 
  fix 
  

   accurately 
  the 
  bounds 
  of 
  the 
  formation. 
  The 
  following 
  sections 
  

   from 
  Hall 
  2 
  show 
  the 
  details 
  of 
  the 
  succession 
  so 
  far 
  as 
  established. 
  

  

  Near 
  the 
  boundary 
  of 
  the 
  towns 
  of 
  German 
  Flats 
  and 
  Warren 
  

   the 
  strata 
  are 
  exposed 
  along 
  Flat 
  creek. 
  This 
  locality 
  is 
  referred 
  

   to 
  by 
  Hall 
  as 
  Tisdale's 
  mill.

  The 
  Oneida 
  conglomerate 
  below 
  was 
  not 
  observed 
  by 
  Hall, 
  but 
  

   its 
  presence 
  both 
  here 
  and 
  in 
  the 
  vicinity 
  has 
  been 
  determined 
  by 
  

   one 
  of 
  the 
  writers 
  (C. 
  A. 
  H.). 
  The 
  ore 
  can 
  not 
  be 
  seen 
  in 
  place, 
  

   though 
  it 
  occurs 
  as 
  float 
  in 
  the 
  creek 
  bed. 
  It 
  is 
  of 
  oolitic 
  character.
