What physical feature most distinguishes biotite mica from. Problem 1LR Problem 2LR. Pin On Science Geology Three planes not at 90 degrees. . Cubic cleavage occurs when there are three cleavage planes intersecting at 90 degrees. View the full answer. Hard to tell but harder. Muscovite is also called white mica and biotite is sometimes called brown mica or black mica. Mica like muscovite or biotite also has basal cleavage. Graphite has basal cleavage. If there is more than one cleavage direction what is the angle between cleavage planes NA 90 or Not at 90. No Cleavage conchoidal fracture. Fluorite exhibits perfect octahedral cleavage. What type of cleavage does biotite have. Basal or pinacoidal cleavage occurs when there is only one cleavage plane. Non-metallic black Slightly harder than glass. 2 cleavages at about 90. When biotite is separated into thin sheets the sheets a...
