Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets. [1] [2] [3]
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.

Spheroidal weathering of exposed sections of the dykes has focussed on cooling joints present within the body of intrusive rock. Radiometric dating of the dykes has returned ages of around 52 million years for their emplacement though an older age of around 61 million years has also been suggested by measurements.
