Molybdenite crystal habit
WebHabit: Blocky - Crystal shape tends to be equant (e.g. feldspars). Habit: Earthy - Dull, clay-like texture with no visible crystalline affinities, (e.g. howlite). Habit: Tabular - Form dimensions are thin in one direction. … WebMolybdenite is extremely soft with a metallic luster, and is superficially almost identical to graphite, to the point where it is not possible to positively distinguish between the two minerals without scientific equipment. It usually has a higher luster than graphite. Crystal habit: Thin, platy hexagonal crystals terminated by pinacoidal faces,
