Geology cleavage definition

WebMay 28, 2024 · Disjunctive fracture cleavage with shear movement is not a “true” foliation in terms of finite strain: it is a false cleavage. Solution cleavage. Solution cleavage consists of regularly spaced dissolution surfaces (e. stylolitic joints) that divide the rock into a series of microlithons without internal deformation. WebDefinition; acicular: A mineral consisting of fine needle-like crystals. adamantine: A brilliant luster like that of a diamond. aggregate: a. A mass of rock particles, grains of minerals, or both. b. Irregular mass of crystals. c. Sand, gravel, crushed stone or rock that forms the major part of concrete. alkaline:

WebCleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage. WebSep 18, 2024 · Cleavage.
