WebGeometric Models. Cleavage means the separation by breakage of a mineral into fragments across planes of weakness in chemical bonds. Because the orientation of ions and molecules in a mineral is geometrical and repetitive, minerals fragment into the same geometric shape - for example, bigger cubes and smaller cubes. WebMinerals within a solid solution group can have very different color characteristics in hand sample (as shown in Figure 2.6.6) and under the microscope. Figure 2.6.4.

WebFracture propagation occurs at an estimated speed between 50% and 60% of the shear wave, therefore between 650 and 1000 m/s, and for this reason we can speak of ultrasonic speed. At these speeds, the fractures tend to fork after just 25–30 μm, and the crack tip transit times are therefore in the order of 30 ÷ 50ns. celery with peanut butter

WebFracture is the property of a mineral breaking in a more or less random pattern with no smooth planar surfaces. Since nearly all minerals have an orderly atomic structure, individual mineral grains have internal axes of length, width, and depth, related to the consistent arrangement of the atoms.
