WebBiotite forms in books like muscovite and the other sheet silicates so it'll be thin and platey. Pyroxene in hand samples has a very faint green hue to it, also it has 90° cleavage so it'll form little black-green right angles Amphibole is kinda shiny, pure black and has 60/30 cleavage so it'll form little pointed crystals.
