Shrinkage Crack Polygon

Reference work entry
DOI: https://doi.org/10.1007/978-1-4614-3134-3_420

Definitions

Shrinkage crack polygon: structure appearing in sedimentary or volcanic rock layer formed by tension due to shrinkage, structure in soil layer formed by tension due to shrinkage of smectitic clay within layer.

Subaerial: formation of desiccation crack polygon due to pore water loss in drying sediment.

Synaeresis: subaqueous cracking of sediment (Plummer and Gostin 1981; Astin and Rogers 1991; Tanner 1998).

Thermal crack polygon: shrinkage crack polygon formed due to cooling in permafrost or lava.

Dehydration: crack polygon formed as a result of loss of crystallographic water, e.g., hydrated salts (Kargel 2004).

Category

A type of  patterned ground.

Synonyms

Subtypes

Crack Classification (Plummer and Gostin 1981): Cracks are orthogonal (or rectangular) when cracks intersect at 90° angles, and they are not propagated simultaneously, but slowly....
