WebIn quartz, all of the bonds are of the same strength (strong silicate bonds), and the geometry of the mineral is such that you can not find a plane that will cut through all of the bonds, therefore the fractures must "wander" creating the conchoidal structures. In mica, the cleavage planes form between the silicate sheets. WebApr 17, 2024 · Two cleavage directions: may define an elongate prism and are said to have prismatic cleavage. ….
