The mineral occurs in carbonate-talc rocks (Jan, 1968), carbonate-bearing talc
schist (Kazmi, pers. comm.), and in quartz veins found along shear zones that lie
along the contact of greenschists and phyllitic schists (Davies, 1962). Associated

Grains of garnet, epidote, pyribole and tourmaline may also occur. The matrix is
composed of very small grains described above, and of clay, sericite, and calcite
(which also is a cementing material). The cement is calcareous but at places ...
