To quickly assess the difficulty of the text, read a short excerpt:
Zoisite has parallel extinction, different color, and smaller optic angle. Clinozoisite has different cleavage (001:100 = 6437'), and usually abnormal interference colors. Staurolite occurs in crystalline schists as a contact or dynamo-metamorphic mineral. In- clusions symmetrically arranged or in subparallel bands are common. The yellow, red, or brown color, the pleochroism, c = red-brown, a and b = yellow, the parallel extinction, the large optic angle, 2V = 89, giving a straight bar in secti...ons at right angles to an optic axis, separate it from other minerals. Andalusite is negative and has different pleochroism, g e d r i t c has smaller optic axial angle (2V = 57-79) and amphibole cleavage, anthophyllite has amphibole cleavage and is rarely pleochroic in thin sections, vesuvianite has a pale yellow color, is negative, and has lower birefringence. Clinochlore, one of the chlorites, occurs in leaves, scales, plates, or leafy aggregates as a min- eral of schists and serpentines, and as a secondary mineral in igneous rocks from the alteration of ferromagnesian silicates.
