What is Calcite? A Basic Definition

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}.
   [1913 Webster]

   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.
         [1913 Webster]
