﻿Report 
  of 
  the 
  State 
  Geologist. 
  245 
  

  

  Fragments 
  of 
  the 
  rock 
  appear 
  to 
  have 
  become 
  detached 
  and 
  sunk 
  

   down 
  into 
  the 
  salt 
  and 
  the 
  spaces 
  left 
  are 
  filled 
  with 
  salt. 
  

  

  The 
  general 
  character 
  of 
  the 
  salt 
  beds 
  is 
  the 
  same 
  at 
  all 
  of 
  the 
  

   mines. 
  

  

  The 
  upper 
  part 
  of 
  the 
  upper 
  bed 
  contains 
  more 
  or 
  less 
  clayey 
  

   shale 
  not 
  in 
  layers, 
  but 
  in 
  fragments 
  and 
  occasionally 
  large 
  

   masses 
  mixed 
  with 
  the 
  salt 
  in 
  such 
  a 
  manner 
  that 
  no 
  lines 
  of 
  

   deposition 
  appear. 
  In 
  s<rne 
  places 
  this 
  "mixed 
  salt' 
  1 
  is 
  very 
  

   clear 
  and 
  entirely 
  free 
  from 
  rock, 
  in 
  others 
  the 
  prOporti 
  n 
  of 
  

   rock 
  is 
  considerable. 
  

  

  The 
  depth 
  to 
  which 
  this 
  condition 
  extends 
  varies 
  greatly 
  

   and 
  abruptly.' 
  In 
  some 
  places 
  it 
  affects 
  but 
  a 
  few 
  feet 
  

   and 
  at 
  others 
  reaches 
  almost 
  to 
  the 
  bottom 
  of 
  the 
  bed. 
  

  

  In 
  the 
  lower 
  part 
  of 
  the 
  upper 
  bed 
  the 
  salt 
  is 
  stratified, 
  and 
  

   the 
  nearly 
  level 
  lines 
  of 
  deposition 
  are 
  ^ery 
  distinct, 
  a* 
  the 
  layers 
  

   vary 
  from 
  transparency 
  or 
  opaque 
  white 
  to 
  gray. 
  The 
  crystals 
  

   are 
  smaller 
  and 
  the 
  whole 
  mass 
  is 
  compact 
  in 
  appearance 
  and 
  

   nearly 
  uniform 
  in 
  character. 
  

  

  This 
  bed 
  of 
  homogeneous 
  salt 
  rv 
  sts 
  conformably 
  on 
  

   a 
  stratum 
  of 
  limestone 
  which 
  appears 
  to 
  be 
  persistent, 
  and 
  

   throughout 
  nearly 
  the 
  whole 
  of 
  the 
  salt 
  field 
  separates 
  the 
  two 
  

   principal 
  beds 
  of 
  salt. 
  This 
  rock 
  shows 
  many 
  fractures 
  and 
  is 
  

   full 
  of 
  thin 
  seams 
  and 
  veins 
  of 
  salt, 
  but 
  has 
  not 
  been 
  very 
  much 
  

   disturbed 
  from 
  its 
  original 
  position 
  and 
  condition. 
  It 
  dips 
  

   toward 
  the 
  west 
  at 
  the 
  rate 
  of 
  eight 
  to 
  twelve 
  inches 
  in 
  100 
  feet 
  

   in 
  the 
  Livonia 
  mine. 
  If 
  the 
  salt 
  beds 
  have 
  the 
  same 
  inclination, 
  

   they 
  would 
  reach 
  the 
  level 
  of 
  the 
  beds 
  in 
  the 
  Genesee 
  valley 
  in 
  

   four 
  or 
  five 
  miles. 
  This 
  interstratified 
  bed 
  of 
  rock 
  is 
  only 
  seven 
  

   and 
  one-half 
  feet 
  thick 
  in 
  the 
  Livonia 
  shaft, 
  while 
  in 
  the 
  Genesee 
  

   valley 
  the 
  records 
  show 
  it 
  to 
  be 
  twenty 
  to 
  thirty 
  feet 
  thick. 
  

  

  At 
  the 
  Lehigh 
  shaft 
  the 
  rock 
  beneath 
  the 
  stratified 
  salt 
  was 
  

   two 
  feet 
  thick. 
  

  

  The 
  records 
  of 
  the 
  wells 
  in 
  the 
  "Warsaw 
  district 
  give 
  very 
  

   little 
  information 
  on 
  this 
  point. 
  

  

  In 
  the 
  Warsaw 
  company's 
  well 
  the 
  two 
  beds 
  of 
  salt 
  were 
  sep- 
  

   arated 
  by 
  ten 
  feet 
  of 
  shale, 
  in 
  the 
  Kerr 
  wells 
  by 
  thirty-one 
  feet, 
  

   in 
  the 
  Duncan 
  well 
  by 
  forty-five 
  feet 
  and 
  in 
  the 
  Gainesville 
  

   well 
  by 
  twenty-eight 
  feet.
