List of places with columnar jointed volcanics

From Wikipedia, the free encyclopedia
Basalt columns seen on Porto Santo Island, Portugal

Columnar jointing of volcanic rocks exists 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]



Garni Gorge, Armenia
Curved columns of rhyolitic tuff at the Hong Kong High Island Reservoir
Interlocked basaltic columns at the top of Kavadia mountain at Dewas district in India.
Columnar basalts at Cape Stolbchatiy, Kuril Islands, Russia


China (mainland)[edit]

  • Heiyuhe Columnar Joints (黑鱼河柱状节理) [Xianrenqiao (仙人桥)], Longchuan River (龙川江) & Black Fish River, Tengchong

Hong Kong[edit]

  • Basalt Island area, Hong Kong; including High Island Reservoir area, Hong Kong; although the High Island Reservoir is not basalt but rhyolitic tuff, rich in potash feldspar and quartz phenocrysts.


In India, columnars are found in several places across the volcanic traps such as 6.5 crore or 65 million years ago (Mya) old deccan traps in South India and 14.5 crore or 145 mya old Rajmahal Traps in Eastern India.

Madhya Pradesh
  • Kavadia Pahad columnars: Forest area near Bagli & Pipari village of Dewas District in Madhya Pradesh. The rock formation is at Kavadia Pahad which is a series of seven mountain ranges.[5]
  • Linga columnars: 11 kilometres (6.8 mi) south of Chhindwara city.
  • Narsinghpur columnar joints in Deccan Basalts near Narsinghpur.

Beyond Earth[edit]

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). Notable among them are formations in the Marte Vallis.[37]


A view of Gunung Padang

A likely Hindu-origin ancient site at Gunung Padang in West Java, Indonesia was built by horizontally laying basalt columns to form terraces on the slope of a hill and creating open-roofed chambers by erecting vertical columns. A now-ruined thirteenth-century religious complex called Nan Madol was built using columnar basalt quarried from various locations on the island of Pohnpei in Micronesia.

Hexagonal basalt was used to build retaining walls by early settlers in some places around Dunedin in New Zealand.
