What Is Columnar Jointing In Geology. Columnar jointing is a common feature of solidified lavas, sills and dikes, but the factors controlling the characteristic stoutness of columns remain debated, and. Columnar jointing consists of sets of regularly spaced parallel fractures (joints) that intersect in a roughly prismatic pattern. (basalt makes up about 90% of all the lava rock on earth.) Columnar jointing forms in lava flows, sills, dikes, ignimbrites (ashflow tuffs), and shallow intrusions of all compositions. These columns of rock are most likely a volcanic rock called basalt. As volcanic rocks cool after being erupted onto the earth's surface in flows or being formed into intrusive sheets below ground, they usually shrink.
