  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Zeolite  \Ze"o*lite\,  n.  [Gr.  ?  to  boil  +  -lite:  cf  F. 
  z['e]olithe.]  (Min.) 
  A  term  now  used  to  designate  any  one  of  a  family  of  minerals, 
  hydrous  silicates  of  alumina,  with  lime,  soda,  potash,  or 
  rarely  baryta.  Here  are  included  natrolite,  stilbite, 
  analcime,  chabazite,  thomsonite,  heulandite,  and  others 
  These  species  occur  of  secondary  origin  in  the  cavities  of 
  amygdaloid,  basalt,  and  lava,  also  less  frequently,  in 
  granite  and  gneiss.  So  called  because  many  of  these  species 
  intumesce  before  the  blowpipe. 
 
  {Needle  zeolite},  needlestone;  natrolite.
