Cleavage is a type of secondary foliation associated with fine grained rocks. For coarser grained rocks, schistosity is used to describe secondary foliation. There are a variety of definitions for cleavage, which may cause confusion and debate. The terminology used in this article is based largely on Passchier and … See more Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism. The degree of deformation and metamorphism along with rock … See more The presence of fabric elements such as preferred orientation of platy or elongate minerals, compositional layering, grain size variations, etc. … See more Cleavages display a measurable geometric relationship with the axial plane of folds developed during deformation and are referred to as axial planar foliations. The foliations are … See more • Cleavage (crystal) • Dynamic quartz recrystallization See more The development of cleavage foliation involves a combination of various mechanisms dependent on the rocks composition, tectonic processes, and metamorphic … See more In geotechnical engineering a cleavage plane forms a discontinuity that may have a large influence on the mechanical behavior (strength, deformation, etc.) of rock masses in, for example, tunnel, foundation, or slope construction. See more WebCleavage. The term cleavage refers to the way a mineral cleaves, or breaks, in prefered directions. Cleavage directions represent planes of weak bonding in the mineral's atomic structure. Because mineral structures are repetitive, a single cleavage often appears as multiple cracks, all parallel. If there is only one direction of atomic weakness ...
