chabasite

CHABASITE, n. A mineral which has been regarded as a variety of zeolite. It is divisible into very obtuse rhomboids.

This mineral occurs in crystals, whose primitive form is nearly a cube.

Chabasie has a foliated structure; its fracture is somewhat conchoidal or uneven, with a glistening vitreous luster. It is translucent, sometimes transparent. Its color is white or grayish white, sometimes with a rosy tinge. Before the blowpipe, it intumesces a little, and easily melts into a white spongy mass.
