  Calcite  \Cal"cite\  (k[a^]l"s[imac]t),  n.  [L.  calx,  calcis, 
  lime.]  (Min.) 
  Calcium  carbonate,  or  carbonate  of  lime.  It  is  rhombohedral 
  in  its  crystallization,  and  thus  distinguished  from 
  aragonite.  It  includes  common  limestone,  chalk,  and  marble. 
  Called  also  {calc-spar}  and  {calcareous  spar}. 
 
  Note:  Argentine  is  a  pearly  lamellar  variety;  aphrite  is 
  foliated  or  chalklike  dogtooth  spar,  a  form  in  acute 
  rhombohedral  or  scalenohedral  crystals;  calc-sinter  and 
  calc-tufa  are  lose  or  porous  varieties  formed  in 
  caverns  or  wet  grounds  from  calcareous  deposits;  agaric 
  mineral  is  a  soft,  white  friable  variety  of  similar 
  origin;  stalaclite  and  stalagmite  are  varieties  formed 
  from  the  drillings  in  caverns.  Iceland  spar  is  a 
  transparent  variety,  exhibiting  the  strong  double 
  refraction  of  the  species,  and  hence  is  called  doubly 
  refracting  spar.
