http://courses.geo.utexas.edu/courses/303/303_lab/mineralsLab303.html Cleavage, in mineralogy and materials science, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the naked eye. If bonds in certain directions are weaker tha…

Web17. avg 2024. · One perfect cleavage (as in mica) develops on the top and bottom of the mineral specimen with many parallel cracks showing on the sides but no angle of intersection. Two cleavage planes intersect at an angle. Common cleavage angles are 60°, 75°, 90°, and 120°. Amphibole has two cleavage planes at 60° and 120°. WebCleavage directions represent planes of weak bonding in the mineral's atomic structure. Because mineral structures are repetitive, a single cleavage often appears as multiple …

WebCleavage is a reproducible property, that is, if you see a smooth surface on a mineral and are able to reproduce that smooth surface by striking the mineral, then that smooth surface is known as a direction of cleavage. Minerals may have 1, 2, 3 or even 4 directions of cleavage (Figure 1). Web20. avg 2009. · you're looking at a cleavage face.
