Basalt columns seen on Porto Santo Island.

Columnar jointed volcanic rocks exist in many places on Earth. Perhaps the most famous basalt lava flow in the world is the Giant's Causeway in Northern Ireland, in which the vertical joints form polygonal columns and give the impression of having been artificially constructed.

Notable columnar jointed volcanics[edit]

Africa[edit]

Curved columns of rhyolitic tuff at the Hong Kong High Island Reservoir

This may have formed from contractional cooling of basltic lavas.

Several exposures of columnar jointing have been discovered on the planet Mars by the High Resolution Imaging Science Experiment (HiRISE) camera, which is carried by the Mars Reconnaissance Orbiter (MRO).

Uses[edit]

A now-ruined thirteenth-century religious complex called Nan Madol was built using columnar basalt quarried from various locations on the island of Pohnpei.
