WebSlaty cleavage is evident from the way the rock has broken and also from lines of weakness that same trend. [SE] The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8). As already noted, slate is formed from the low ... WebCleavage is a type of rock foliation, a fabricelement that describes the way planar features develop in a rock. Foliation is separated into two groups: primary and secondary. Primary deals with igneous and sedimentary rocks while secondary deals with rocks that undergo metamorphism as a result of deformation.
WebRock cleavage is caused by stress or pressure to the rock that causes it to deform. It can also be caused by metamorphism when rocks or minerals grow or change when exposed to intense heat...
