The world's most famous columnar basalt
The dense lava flow is cooled, contracted at a vertical angle, and decomposed in the direction perpendicular to the lava flow direction to form a distinctive geometry, which is the formation of a columnar basalt, which has a regular hexagonal shape, Even close to the artificially manufactured specifications.The world's most famous pillar basaltic structure includes: the Irish coast "Giant's Causeway" (Giant's Causeway), the largest and widely recognized by the United States Wyoming's "Devil Tower" (Devil's Tower).
As early as 60 million years ago in the Pacific era, in the west of Scotland in the west of the inner Hebrew Islands line to the eastern part of northern Ireland volcano is very active, a stock of basalt rock melt flow from the cracks in the crust, the thick lava flow to Vertical angle contraction, and lava flow direction perpendicular to the direction of decomposition will form a different geometric shape, many lava cooling to form a regular hexagonal columnar basalt.
The giant road is the world's most famous columnar basaltic structure, located about 80 kilometers northwest of Belfast, Northern Ireland, on the Atlantic coast, consisting of a total of about 40,000 hexagonal pillars consisting of 8 kilometers of coast. Extending into the sea.
