SCOLECITE

This article appears in Volume V24, Page 407 of the Encyclopedia Britannica.

Encyclopedia Britannica - Main :: SAR-SCY
SCOLECITE , a
mineral
  belonging to the zeolite group; a hydrated
calcium
  silicate, CaAl2Si3Oio+3H20. It is a lime-zeolite, and like the soda-zeolite natrolite and the soda-limezeolite mesolite, usually occurs as acicular and fibrous aggregations. Although having nearly the same interfacial angles as the orthorhombic natrolite, it crystallizes in the monoclinic
system
 , and, as shown by the etched figures and the pyroelectric
character
 , in the hemihedral class of this
system
 , there being a plane, but no
axis
 , of symmetry. Scolecite can therefore be distinguished from natrolite by an
optical
  examination, since the acicular crystals do not extinguish parallel to their length between crossed nicols. Twinning on the ortho-pinacoid is usually evident. The
mineral
  is colourless or
white
 , transparent, and vitreous in lustre: the hardness is 52, and the specific gravity 2.2. It is a mineral of secondary origin, and occurs with other
zeolites
  in the amygdaloidal cavities of weathered volcanic rocks of basic composition. Fine divergent groups of prismatic crystals are found in the basalt of Berufjord near Djupivogr in Iceland and in the
Deccan
  traps near
Poona
  in India; hence the synonym poonahlite for this species. The name scolecite is derived from Gr. arcwAnE, a worm, because the crystals sometimes curl up like worms when heated before the blowpipe. (L. J. S.)
