Suppose strange stone pillars along Australia's coast

The southern coast of Tasmania state in Australia impresses with adjacent stone columns rising 300m above the sea.

Geologists call the strange stone column structure on the southern coast of Tasmania, which is dolomite with a long, six-edge shape.

Dolerite forms when molten rock is pushed up from the ground to rapidly crystallize to form crystals in the rock.At proper cold temperatures, the stone shrinks and cracks.

The cracks allow the inside of the rock to be cooled and result in more cracks.Finally, a large rock formed with long fissures and 5 or 6 sides.

Dolerite geological columns are from a few centimeters to a few meters in diameter.

Tasmanian dolerite columns seem to have formed from the Jurassic period, about 185 million years ago.This is the time when volcanoes cover one third of this state.

These strange stone pillars are in fact a wall of continuous structures that span more than 4,000km from Australia to Antarctica.

The cylindrical stone structure is not uncommon and visitors can find similar structures in hundreds of locations around the world such as Giant's Causeway in Ireland, Los Organos in Spain .
