tremolite
n 1: a white or pale green mineral (calcium magnesium silicate)
of the amphibole group used as a form of asbestos

Tremolite \Trem"o*lite\, n. [From Tremola, a valley in the Alps,
where it was discovered.] (Min.)
A white variety of amphibole, or hornblende, occurring in
long, bladelike crystals, and coarsely fibrous masses.
[1913 Webster]


Amphibole \Am"phi*bole\ ([a^]m"f[i^]*b[=o]l), n. [Gr.
'amfi`bolos doubtful, equivocal, fr. 'amfiba`llein to throw
round, to doubt: cf. F. amphibole. Ha["u]y so named the genus
from the great variety of color and composition assumed by
the mineral.] (Min.)
A common mineral embracing many varieties varying in color
and in composition. It occurs in monoclinic crystals; also
massive, generally with fibrous or columnar structure. The
color varies from white to gray, green, brown, and black. It
is a silicate of magnesium and calcium, with usually
aluminium and iron. Some common varieties are {tremolite},
{actinolite}, {asbestus}, {edenite}, {hornblende} (the last
name being also used as a general term for the whole
species). Amphibole is a constituent of many crystalline
rocks, as syenite, diorite, most varieties of trachyte, etc.
See {Hornblende}.
[1913 Webster]
