Web·Color - Hornblende is generally pleochroic in shades of brown and green, less commonly yellow or red-brown. Concentric or patchy color zonation may be present. Actinolite is similar but colors are restricted to greens. ·Cleavage - Amphiboles have diagnostic 60 o-120 o cleavage angles when viewed in end section.

Hornblende has a hardness of 5–6, a specific gravity of 3.0 to 3.6, and is typically an opaque green, dark green, brown, or black color. It tends to form slender prismatic to bladed crystals, diamond-shaped in cross-section, or is present as irregular grains or fibrous masses. Its planes of cleavage intersect at 56° and 124° angles. Hornblende is most often confused with the pyroxene series and biotite mica, which are also dark minerals found in granite and charnockite. … WebAppearance of crystals in microscope. The optical properties of minerals refer to their behavior in the presence of light and how they interact with light when observed using various optical techniques. These properties include transparency/opacity, color, luster, refractive index (RI), pleochroism, birefringence, dispersion, extinction, and ...
