Cleavage is a type of rock foliation, a fabric element 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 … 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. determines what type of cleavage forms. Cleavage is categorized as either continuous or spaced. 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 symmetrically arranged with respect to the axial plane, depending on the composition … 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, … See more • Cleavage (crystal) • Dynamic quartz recrystallization See more WebMar 2, 2024 · Geologist define rock as aggregates or mass composed of one or more commonly, several of minerals.
