As a result, they occur as families of joints that form recognizable joint sets. Typically, exposures or outcrops within a given area or region of study contains two or more sets of systematic joints, each with its own distinctive properties such as orientation and spacing, that intersect to form well-defined joint systems.

Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as joints, result in the formation of a regular array of polygonal prisms (basalt prisms), or columns. Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts.
Systems geology emphasizes the nature of geology as a system – that is, as a set of interacting parts that function as a whole. [1] [2] [3] The systems approach involves study of the linkages or interfaces between the component objects and processes at all levels of detail in order to gain a more comprehensive understanding of the solid Earth.
In geology and geomorphology, a tessellated pavement is a relatively flat rock surface that is subdivided into 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 .
In geotechnical engineering, a discontinuity (often referred to as a joint) is a plane or surface that marks a change in physical or chemical characteristics in a soil or rock mass. A discontinuity can be, for example, a bedding , schistosity , foliation , joint , cleavage , fracture , fissure , crack, or fault plane.
Whelp, that sure was a lot of blowouts in the first round of the College Football Playoff. On this week's overreaction pod, Dan Wetzel Ross Dellenger and SI's Pat Forde acknowledge what led to ...
Conjugate Joints occur when the joints intersect each other at angles significantly less than ninety degrees. Systematic Joints are joint systems in which all the joints are parallel or subparallel, and maintain roughly the same spacing from each other. Columnar Joints are joints that cut the formation vertically in (typically) hexagonal ...
