Web15 jul. 2024 · Geologists rely on several simple tests to identify minerals. These tests are based on a mineral’s physical and chemical properties, which are crystal form, luster, hardness, cleavage, fracture, streak, color, texture, density, specific gravity, and special properties.It is usually best to use a combination of tests instead of just one to identify … Web19 jul. 2024 · Cleavage. Cleavage is the tendency of a mineral to break along certain planes to make smooth surfaces. Halite breaks between layers of sodium and chlorine to form cubes with smooth surfaces (figure 6). A mineral that naturally breaks into perfectly flat surfaces is exhibiting cleavage. Not all minerals have cleavage.
