  Trap 
  

  

  Trap 
  is 
  a 
  name 
  commonly 
  applied 
  to 
  a 
  series 
  of 
  igneous 
  rocks, 
  

   distinguished 
  chiefly 
  by 
  their 
  basic 
  composition, 
  their 
  fine 
  grain, 
  

   and, 
  because 
  of 
  their 
  basicity, 
  by 
  a 
  dark 
  color. 
  In 
  mineral 
  com- 
  

   position 
  they 
  differ 
  from 
  granite 
  in 
  the 
  total 
  absence 
  of 
  quartz 
  and 
  

   by 
  the 
  more 
  basic 
  character 
  of 
  their 
  feldspars. 
  They 
  consist 
  

   mainly 
  of 
  plagioclase 
  (soda 
  lime 
  feldspar) 
  and 
  pyroxene. 
  In 
  

   diabase, 
  by 
  far 
  the 
  most 
  common 
  rock 
  type 
  of 
  the 
  series, 
  the 
  feld- 
  

   spars 
  have 
  crystallized 
  out 
  in 
  needle 
  or 
  lathlike 
  forms, 
  forming 
  

   an 
  interlocking 
  network, 
  with 
  the 
  pyroxene 
  filling 
  up 
  the 
  interstices. 
  

  

  Trap 
  appears 
  usually 
  in 
  two 
  forms 
  of 
  occurrence: 
  (i) 
  as 
  dikes 
  

   which 
  are 
  usually 
  vertical, 
  wall-like 
  masses 
  of 
  rock, 
  which 
  have 
  been 
  

   intruded 
  while 
  in 
  semifluid 
  condition 
  into 
  fissures, 
  from 
  some 
  

   molten 
  mass 
  below; 
  (2) 
  as 
  sheets 
  which 
  are 
  intrusions 
  of 
  similar 
  

   character 
  but 
  which 
  have 
  been 
  forced 
  between 
  the 
  bedding 
  planes 
  

   of 
  sedimentary 
  strata 
  and 
  have 
  a 
  horizontal 
  position. 
  

  

  Of 
  the 
  first 
  type, 
  the 
  dikes, 
  there 
  is 
  an 
  abundance 
  around 
  the 
  

   borders 
  of 
  the 
  Adirondacks 
  especially 
  in 
  Clinton 
  and 
  Essex 
  

   counties. 
  However, 
  owing 
  to 
  their 
  small 
  size 
  or 
  their 
  inaccessi- 
  

   bility, 
  they 
  are 
  with 
  the 
  exception 
  of 
  one 
  near 
  Greenfield, 
  Saratoga 
  

   CO. 
  and 
  one 
  at 
  Little 
  Falls, 
  Herkimer 
  co. 
  of 
  no 
  present 
  commercial 
  

   importance.
