The term tenacity describes a mineral's resistance to breaking or deforming.
Minerals that are ionically bonded, such as fluorite and halite, tend to be brittle and shatter into small pieces when struck.
Minerals with metallic bonds, such as native copper, are malleable, or easily hammered into different shapes.
Minerals, including gypsum and talc, that can be cut into thin shavings are described as sectile.
Others, such as micas, are elastic and will bend and snap back to their original shape after the stress is released.
Two types of micas:
Muscovite Mica -- light in color
Biotite Mica -- dark in color
