[1] Slaty cleavage often occurs after diagenesis and is the first cleavage feature to form after deformation begins. 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 type … See more The presence of fabric elements such as preferred orientation of platy or elongate minerals, compositional layering, grain size variations, etc. determines what type of cleavage forms. Cleavage is categorized as either continuous or spaced. 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 • Cleavage (crystal) • Dynamic quartz recrystallization See more The development of cleavage foliation involves a combination of various mechanisms dependent on the rocks composition, … 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.
