How do hexagonal basalt columns form

WebThese structures are predominantly hexagonal in cross-section, but polygons with three to twelve or more sides can be observed.The size of the columns depends loosely on the rate of cooling; very rapid cooling may … WebContraction stresses developed because the cool solid form of basalt has a lesser volume than the hot liquid form. Cracks, also called joints by geologists, began to form. Jointing releases internal stress created by the cooling and associated contraction. In some locations, such as at the Devils Postpile, the jointing formed columns.
