The Pan Formation of Tessellated Pavement, Lufra, Eaglehawk Neck, Tasmania, Australia Featured 31 Dec 2009 Print

The Pan Formation of Tessellated Pavement, Lufra, Eaglehawk Neck, Tasmania, Australia

Tessellated pavement is a relatively flat rock surface that is subdivided into more or less regular rectangles, blocks approaching rectangles, or irregular or regular polygons by fractures, frequently systematic joints, within the rock. This type of rock pavement bears this name because it is fractured into polygonal blocks that resemble tiles of a mosaic floor, or tessellations. The pan formation is a series of concave depressions in the rock that typically forms beyond the edge of the seashore. This part of the pavement dries out more at low tide than the portion abutting the seashore, allowing salt crystals to develop further; the surface of the 'pans' therefore erodes more quickly than the joints, resulting in increasing concavity
