Pencil cleavage, the Glossary

Index Pencil cleavage

Pencil cleavage in geology refers to a cleavage in rock such that long, slender, pencil-shaped fragments of rock are created by fracturing during the weathering of a sedimentary rock.[1]

Cleavage (geology)

Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism.

See Pencil cleavage and Cleavage (geology)

Diagenesis

Diagenesis is the process that describes physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition.

See Pencil cleavage and Diagenesis

Fracture (geology)

A fracture is any separation in a geologic formation, such as a ''joint'' or a ''fault'' that divides the rock into two or more pieces.

See Pencil cleavage and Fracture (geology)

Geology

Geology is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

See Pencil cleavage and Geology

Sedimentary rock

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation.

See Pencil cleavage and Sedimentary rock

Tectonics

Tectonics are the processes that result in the structure and properties of the Earth's crust and its evolution through time.

See Pencil cleavage and Tectonics

Weathering

Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms.
